Reuleaux Table – The Hors d’oeuvre

25/5/2017

You might say, just not another table project that will drag on for three years. That would be very understandable given my most recent project that necessitated 14 posts. You will therefore be happy to hear that this project is currently almost at the halfway mark and this is the first post. The date above was when I loaded the first set of pictures. At this point it is probably also pertinent to warn the suffragettes amongst us that this post might contain sensitive material.

The Marx family needs a kitchen table able (rather like that two-step) to withstand the eternal destructive forces directed towards every wretched object in our household. The destructive forces are also known as our “offspring” or more specifically Didi and Aoife. To be fair, no piece of furniture including my Roubo workbench will last indefinitely under their perpetual onslaught, but I do not want to have to repeat the exercise within 12 months. To add to the complexity of the brief, I wanted to build something that has a (wait for it …) certain je ne sais quoi.

I rather liked the sort of pagan simplicity of a table design advanced in The Anarchist’s Design Book. Herr Schwarz describes a table that has two thick beams (running diagonally with regards to the grain of the top) under the top into which Windsor-style legs are savagely inserted. This, I am sure, will work exceptionally well if you have a top of reasonable thickness as there are no aprons in his design if I remember correctly. Seeing that I wanted something that would appear more diaphanous, I had to develop the design a wee bit. The other challenge with the peasant design (meant as a compliment rather than derogatory) in Herr Schwarz’ book lie in the lack of inherent stability of my preferred feral African hardwood . Some of the boards I work with will make a late luteal phase female look stable (listen, I warned you, OK!)

The panacea for the stated conundrum seemed quite obvious to me. I needed to incorporate two heavy(ish) beams into a torsion box that would support a light top adequately and resist all other forces such as twist, warping, etcetera. The idea is that the brute strength of the torsion box will be almost invisible to the casual observer while being well hidden underneath the top. All that is supposed to meet the eye is a thin floaty top with four understated yet sophisticated legs protruding (at a barely discernible angle) from it’s belly.

In order to test my ideas on shape and size, I built a very basic model. In terms of proportions, the top is 900 x 2100 mm which makes it a 3:7 ratio. This was dictated somewhat by the space the table is destined for. Seeing that the height is around 770 mm it means that the height is about 1/3 of the length, which seemed like a good ratio. I then added very slight curves to all four sides.

I cannot, for the life of me, find a proper name for this shape. It is basically a rectangle with four convexly curved sides and sharp corners. I will therefore call it a reuleaux rectangle’ (simply because of the enticing alliteration of course), although that is certainly not a formally recognized term. Be that as it may, it is one of the most pleasing shapes in the eye of this humble observer. You might recall a chopping board I have built with the same basic shape.

The lines on the top represent my experiments to find the best rake and splay angles for the legs.

I decided to build the table using Witpeer predominantly and Kershout in very limited amounts to add accent to cardinal curves only.

The legs will have a very slightly tampering (from top to bottom) octagonal shape. The shaping was done by hand planing, in the first place with my shop made scrub plane followed by a no. 606 Bedrock Fore plane. The stock for these legs were made up of two laminated strips of Witpeer. In order to hide the lamination, I marked out the octagon in such a way that the lamination lines run exactly on two of the edges.

19/6/2017 (second set of pictures loaded)

At present (5/2018) the top is in two pieces of the below size …

… and three of the legs are roughly shaped.

I used Tasmanian Blackwood (intruding pest as it is in this part of the world) for that part of the torsion box that will be completely unsighted and Witpeer for the rest. It might sound as if I do not like Tasmanian Black (TB after this), but to the contrary I have a lot of respect for it. My African hardwoods are obviously close to my heart, but the TB did grow on this continent so it is very much local.

Come to think of it, it is very much like my distant German relatives from pre-1710 and I. Not that your average populist majority politician in this part of the world has the intellectual capacity to get this.

Anyway although I find the TB rather difficult to work with (the former being another similarity to my ancestors and I) it has a tenacity second to none. It reminds me of an Australian sports team, although it does not tend to tamper with the ball quite as much (sorry just had to through that in there). The only problem is that I do not have the top end stuff, but rather crappy warped light coloured boards for the most past. The top end stuff can be absolutely spectacular, but mine not so much. Hence why I use it for the unsighted structural parts.

In the picture below you can appreciate one such board. Once you liberate appropriately sized chunks it tends to move, twist, warp etcetera all over the place. I then re-saw these, flip one of the two pieces and laminate them back together so that the apposing forces cancel each other out.

Here I used a Witpeer beam from another project to ensure that the two aprons gets glued absolutely straight. I added a thinner strip of TB to the inside of each apron for strength.

21/5/2018

My torsion box will have two heavy beams at it’s ends. These beams will accept the legs as joined in the same fashion as Windsor chair legs. They are clamp together in the pictures below to mark out the joinery.

Torsion box has four components running longitudinally and five (including the two heavy beams) running diagonal to the aforementioned. The longitudinal components are joined to the beams with through tenons, which will be wedged. The shoulders sit in a rabbet (pictured) to prevent twisting.

This is what the longitudinal components look like. The outside pair (left one in the picture below) is slightly heavier and has a Witpeer face side. The inside (right) pair is made up completely of TB.

Here you can see how the tenons extend through the Witpeer beam and how their shoulders are located in the respective rabbets.

In these two pictures you can hopefully appreciate another cardinal aspect of the way I designed the joinery. Seeing that the legs will be joined to the heavy beams by means of a tapering round tenon fitted in a round mortise reamed to the same angle of taper, it is likely to exert force that might split the beam. A leg mortise will be located between the 1st and the 2nd through tenon on the near side and the 3rd and 4th on the far side. The two wedged through tenons on each side of the leg joinery should (to my mind at least) go a long way towards resisting a potential split.

Next up are the diagonal members of the torsion box. They are joined in exactly the same wedged through tenon fashion to the outside (apron) longitudinal components. Where they cross the two inside components I prepared a type of half lap bridal joint aided by two rabbits to resist twisting.

Chopping out the mortises in the apron components.

This is where we are at for now. Two of the three cross members fitted with one more to be done between them. The two in the picture slide in from the top and the one to follow will slide in from the bottom, which creates a nice mechanical lock once the aprons slide in to place.

I hope you enjoyed the entrée that took us half way through the meal.

My second commission – the peroration

24/4/2018

I am sure that every JNSQ reader must be bored mindless by  now with this tedious series of posts. There is good news for the mentioned brethren though. This is the final nail in your metaphorical coffin.

Speaking of coffins, I almost led the way in ‘taking the ferry’ recently. As you might well know, we progressed to a fairly advanced stage in finishing the top. There were only 2 steps left i.e. laying down a couple of layers of varnish followed by some or other protective wax layer. A walk in the park you would think, hey.

Enter the first product bought in Namibia for this particular project. Yes, yes, I should have known better. Please do not judge me for my naïveté in expecting that something as basic as varnish and the snake oil merchants pushing it, can be trusted. Massive mistake non the less!! (and almost became my oneway ferry ticket).

Actually, one of these merchants really tried to be useful, but I guess it is simply beyond what is possible in the Third World. The so called experts recommended a particular type of varnish, that even the uber-expert in Cape Town (who were phoned for cutting edge advice) confirmed to be the bee’s knees on top of shellac. To cut a long story short, it was a kak recommendation.

The picture below reminds of where we were before I indulged the fallacy that a local product will do as it claims.

This is a picture of the product in question. My guess is that it possibly arrived here several centuries prior to the dinosaur. It is probably a well matured (by now) amoeboid excrement of some description.

One coat of the amoeboid excrement and the top looked like this!! The patchy appearance is due to some of my early efforts to remove the scheiße.

The whole top looked like this after one coat. The varnish basically did not set, it simply formed a soft opaque layer.  What to do …, what to do??

E-mail Don Williams. That is what you do. Being from a civilized part of the world though, he could not work out why this happened, but advise me to try and remove the layer with acetone. Thank you Don, you are a legend.

Another 4 hours of elbow grease and I got most of the stuff off. It necessitated some vigorous scrubbing with an acetone drenched piece of 0000 steel wool.

I then ( neologism warning!!) Mr. Miyagi’ed on another 5 coats of shellac and rubbed the surface down with 0000 steel wool afterwards.

I simply did not have enough balls (so to speak) to try another amoeboid excrement, so decided to rather apply a few layers of wax. Unfortunately, it was also a product I bought locally, but it seemed to work okay. The pictures below show the result.

PS – If anyone out there can point me towards a supplier that sell solid carnauba wax (and ship internationally) I would really appreciate it. I would rather make my own concoctions with the help of Don Williams’ recipes.

As I have mentioned some time ago, I wanted to use a novel system (to me anyway as I have not come across it) to attach the under carriage to the top. The objectives of my system are to allow for wood movement (surprise surprise) and to be easily adjustable in terms of avoiding natural defects such as cracks in the top. It is important to have such a system when working in the Nakashima style where aesthetically pleasing imperfections tend to always end up in locations where they are not particularly helpful from a joinery perspective.  Seeing that 99% of the wood in my collection is of a Nakashimian (if you like) persuasion, I pretty much need a longterm solution.  With this in mind I made ten pairs of the blocks pictured below.

I then found suitable strips of Assegaai (Curtisia dendata) to produce shop made dowels with my no. 77 Stanley dowel maker. Assegaai lends itself perfectly to this job given it’s characteristics of being fine grained, flexible, and stable. My son and I took turns to yank (yes that is yank not …) the lever while the other (individual) guided the blank. It is very difficult to do both these tasks at the same time in dense hardwood such as Assegaai.

Here you can see the first dowel, the Assegaai excrement (never thought I would get the opportunity to use the E-word so often in a single post) emanating from the dowel machine, and some of the pairs of Kershout blocks.

While all that was going  on, the other major parts (of the table) received a few coats of shellac. I cannot tell you how much I enjoy working with shellac. It is absolute magic. I will never ever use anything else. Especially not commercial junk (thought of throwing the E-word in there but you might be getting tired of it by now) made by big companies.

The next step was to drill the holes for the dowels in the aprons.

One of my all time favourite tool companies is L. & I.J. White Co (Buffalo, N.Y.), even though I do not own a single tool with that name on it. I do however have an electronic version of their 1909 catalogue (and an imagination) and that is enough (for now). It helps having an imagination (and a tool catalogue) when you do not have certain things you would like to have. You learn this particular skill on the wrong side of town while growing up.

Anyway when I though of what to put on the copper plate in order to identify the artisan who made the table and date it, I came up with “G. & J.G. Marx 2016-2018”. It is the initials of my late father and I. The dates (I realised too late) should have read 2015-2018, but that is not a major drama. Even though my father never worked on this table, I would never have been able to produce anything close to this if it was not for what he taught me.

I prepared the lion’s share of the joinery of this table during the driest season on the ambient humidity calendar and took great care to ensure that the joints fit quite snug. The reason being that all of the cardinal joints will not be glued. Sort of in the Japanese tradition, I guess. Only problem is, on the 20th of April when the undercarriage were to be assembled it was not the driest time of year.

In fact the ambient humidity was sitting at around 50% for two weeks prior to assembly, whereas the joinery was done at around 20%. What to do …, what to do …. It was not an option to refit the joinery as that would lead to a sloppy fit during the dry season, so I applied wax to the mating surfaces of the joints and reached for the heavy dead blow mallet. I have to admit that it caused one hell of a lot of anxiety.

Imagine pounding away at parts of a project that took you 3 years to complete and as luck would have it, the bridal joints at the top of the Windsor leg resisted matrimonial union the most. Beating the proverbial snot out of the joints with a 1kg shop made dead blow mallet on top of those delicate Kershout spindles felt like sparring with Liv Tyler. Actually, I might be more partial to the latter, but that might represent  an unfortunate deviation from the topic at hand. What I realized though, was that those spindles acting in unison are tremendously robust. After all the violence the undercarriage was assembled without any major disasters. I had no intention of dismantling it (which was the original plan) for the move to it’s new home the next day, even if that meant that the new owners had to demolish half their house to get it in there.

This reminds me of Koos Kombuis who once said “After the riot, peace and quiet!” as a Southern  African take on the the well known fag (as in cigarette) slogan “After action, satisfaction”.

The tool models in the pictures below are (in no specific order) the trusty Nafta and (the ever-so-slightly-less trusty) Aoife.

The use of a single screw to secure each bridal joint for centuries to come, probably fall into the overkill department, but I cannot help myself.

By the way you can also appreciate the Peter Galbertian wedges at the top of the spindles in the picture below.

The gaps in the bridal joint you can see here, allow for wood movement.

I listened to ‘Roadie’ as performed by my favourite Kiwi band ‘Fat Freddy’s Drop’ while attaching the undercarriage to the top. I never knew what the word ‘Roadie’ meant so though I should have a look while writing this post. Turns out it was quite an apt anthem for this particular task/project.

Speaking of ‘trusty’ and ‘overkill’, here you can appreciate an activity that would represent an overkill with a tool that can be described as trusty. Cutting the dowels with a Langdon Mitre Box with a makeshift stop to ensure uniformity in length, could possibly represent the early stages of losing one’s mind, but at least it implies some form of insight on behave of the sufferer.

I hope the pictures below will do an efficient job of explaining how my system of attaching the undercarriage to the top allows for wood movement and provides flexibility in term of avoiding imperfections in the top. In the first example we do not need to avoid anything so this is the standard setup. Both the dowels and the holes through the apron are ¼” in diameter. The holes in the block that fit over the dowels are around the 9/16″ mark, which should ensure friction free movement.

I used spacers to ensure consistent and parallel gaps between the blocks and the apron while marking out the exact location of the pilot holes for the screws.

Here we have the standard setup.

The example below illustrates how this system allows some flexibility in positioning of the blocks. As you can see, the dowels were cut slightly longer to reach across the Fish River Canyon (so to speak) to ensure that the screw through the block hits solid wood on the far side.

In order to hold the top down as close to the edge as the design of the undercarriage would allow, I came up with the this idea. The block of wood to the right of the protruding dowel slides over it and gets locked down with two screws.

The transport to the table’s new home went surprisingly smooth. Once there I reattached the top and Bob’s your Uncle. The new owner did enquire why I had such a pronounced tremor on me and despite drinking far too much over many years it was most definitely predominantly due to the anxiety associated with ensuring that this labour of love reach it’s destination safely.

I hope you will allow me the excessive number of photos that follow.

Finally, all that is left to say is, thank you Jan Gerhardus Marx. Thank you.

My Second Commission – Part 13

24/3/2018

Well it has been a long time since publishing the previous post in this series. I do not want to elaborate on the reasons, but cherish the opportunity to be back live with an update.

In the previous post we got as far as preparing the top of the table to the stage of applying tung oil and finishing most of the joinery.

In this edition we will look at the next few stages in the finishing of the top and a little bit more joinery. In the picture below you can appreciate (I hope) what the legs look like in relation to the top, in an upside down universe.

That reminds me, I should probably give you an aide-mémoire of what we are aiming for. Here are a few pictures of the model I’ve built to test the design and dimensions et cetera. It might make the upended universe easier to interpret.

We will start our discussion with some joinery. The über-beam at floor level mates with (please excuse the sexual references, but I am a psychoanalytically inclined Psychiatrist so what do you expect?) the bottom of the Windsor leg by means of a half ass bridal joint (if you like??).  The execution of which should be apparent in the following pictures.

After an extensive search for quality Beeswax in Sub-Sahara Africa I finally received something that resembles what the bees actually produced from the Capital of ludicrously embarrassing Afrikaans music. I am of course referring to Snor City (the City of the Moustache) aka Pretoria.

At this stage I was still hunting for blonde shellac, but went ahead with the next phase of finishing i.e. working beeswax into the extremely fine grain of the Kershout using a polissoir Don Williams sent me. He sent me two of these puppies, one of which I used to burnish the surface and the other to coax the wax into the grain. The latter polissoir were first soaked in heated wax to impregnate (there we go again) the fibers of the business end. (Don, these tools work like a charm, thank you mate!)

Below we have a final look at what the Kershout top looked like after burnishing it’s oiled face side.

Now we get into the ancient process of French polishing as performed by a complete neophyte, so please do not follow any of these steps if you know better or saw a qualified person at work. What I did was to rub beeswax onto the surface like so …

The beeswax was then rubbed into the previously burnished surface using an impregnated (now please stop) polissoir.

The next step involves a hardwood block that is used similar to a scraper blade to remove the excess wax. That is followed by buffing off the last little bit of excess wax with a clean grippy cloth (unfortunately not pictured).

The picture below was taken before the buffing with a cloth.

At this stage I received a mysterious package from the US of A. It contained 6 pounds of premier quality lemon blonde shellac powder from that man called Don “L’ Art Du Menuisier” Williams. It was a present straight from heaven. Here in Deep Dark Africa it is next to impossible to obtain anything that resembles the quality of the shellac I received.

I decided to prepare a 1 pound cut to start out with. The idea was that it should be easier to apply a thin cut if the polisher is inexperienced. Before applying anything though, one needs to fashion a makeshift rubber. Mine consisted of old t-shirt fabric rolled into a bit of a tube-like shape wrapped by some more fabric which was tied with a cable tie to form the object pictured below.

In order to get some idea of what I was supposed to do I read the pertinent passages on French polishing in the 1897 classic “Wood Finishing” edited by Paul N. Hasluck. I found the bit where he explained that no one should even attempt to French polish “articles of value before considerable practice on unimportant articles” particularly encouraging. Luckily a few other sources demystified the process sufficiently for me to roll the dice on a table top that took me the best part of two years to prepare to it’s pre-shellac state.

Do you remember Mr. Miyagi? He was Daniel-san aka the Karate Kids’ master in an epic example of American motion pictures. You know the type, the good guys win, the bad guys lose and everyone is happy ever after (unlike real life in the rest f the world). Well what I did was basically the “wax on, wax off” (actually only “on” I hope) routine to apply the shellac. I wiped it on using very tight circular motion like Daniel-san on those old cars that looked like they escaped from Cuba. I applied three layers in one go, as once you have applied the first layer the shellac is already sufficiently dry at the location where you started to repeat the process.

After each set of tree layers the surface was rubbed down with this contraption. I used a shop made sanding block and replaced the sandpaper with 0000 steel wool.

After a good rub with the my new über-tool, I applied another three layers. Miyagi-san continued in this way until the top sported 18 layers. At that stage I was ready to kick Daniel-san’s arse. Metaphorically speaking of course. The effect of my efforts up to that point can be seen in the picture below.

The top then received another sanding with the 0000 steel wool. Now I need to find a varnish that will add a hard shell. I am still not too sure what that might be, but would take advice from anyone who would like to send me some! Just joking of course.

I decided to mask off the edges to ensure that they stay dull in appearance to create contrast and visual interest.

Let’s get back to the joinery. The heavy beam that runs close to floor level is joined to the trapezoid leg by means of a wedged through tenon. For the mortise I drilled out the waste with an Irvin pattern auger bit and chopped to the knife line with a chisel.

The tenon followed.

The fit seemed quite acceptable.

The mortise for the wedge has a 9° slope. I used the Charlesworthian prop pictured below to ensure accurate chiseling of the slope.

So okay, one of the reasons for my radio silence is that my father passed away after a very short battle with cancer. Seeing that he taught me almost all I know, it has been a bit weird spending time in the shop. I am sure we will discuss this in more detail at some point in future as it must be a fairly common phenomenon for a lot of woodworkers.

For now however, I thought it pertinent to include an impromptu design alteration to dedicate the piece in his memory. The carving was done free hand with a 1/8″ bevel edge chisel after drawing the design free hand on the tenon with a pencil. It was repeated on the opposite side.

The enforced lamination of the beam were disguised  by the same set of beads as was used on the Kershout beams of the Windsor leg.

My son Didi prepared for his entrance exam at Bishops in the shop while I worked. He has his heart set on becoming a Bishops Boy next year when he goes to secondary school.

While Didi got stuck into his books, I softened the look of the Windsor legs. The beam that forms the foot of the leg received a very slight curve (to it’s sole) to ensure that it would sit stable on an uneven floor and the sharp edges were rounded over somewhat.

I like doing this very much in an organic fashion. I mark out the curved sides with an appropriately sized washer and draw the guiding lines across using a finger as a fence. It is then shaped by hand using two rasps and a sanding plane.

I quite like the way the beads disappear in the picture below.

All that remained was to apply a tung oil-turps mixture, which would then have about three weeks to settle during the Easter break before we apply beeswax. I tend to try and keep the surface wet with the oil mixture for an hour or so and then wipe off the excess with a clean cloth.

Here are a few pre-oil pics.

Followed by just-oiled pics.

The book matching of the below aspect is starting to emerge quite nicely.

So there we go. Hopefully back with a vengeance.

My second commission – part 12

19/6/2017

Let’s start with a confession. I did stuff around with some of the photos in this post. It is the first time that any of JNSQ’s photos have been altered, as far as I can remember anyway.

The previous posts in this series can be found here.

In this edition we will take a look at some of the joinery and the first phase of preparation of the top for finishing.

The first bit of joinery I attempted was to fit a small block to the top of each leg construction. It will be the point that fix the centre of the leg to the centre of the top. All the other connection points will allow for wood movement, but these two will not. This means that the top will be able to move freely with changes in humidity, but the centre will remain fix to the centre of the legs. I think this is called a T-bridle joint. One feature of my Langdon mitre box and saw that came in handy here was it’s ability to set the depth of cut. Obviously you can simply do this by hand, which would also be much quicker. Where the mitre box might have an advantage is when you need to do heaps of these joints with the same dimensions. In this case it was an opportunity to work out how to set the mitre box for a job like this. That way it will be easier next time.

A router plane works well for the cheeks of the bridal section. It was a bit of a challenge to hold such a small piece while cutting the cheeks to depth. The solution was two dogs and a Veritas gadget. That could be a good name for a progressive rock band or a retrogressive gin mill (Two dogs and a Veritas gadget), come to think of it.

Next up were the slots in the top of the legs.

The two aprons are also jointed to the legs by means of T-bridal joints. Here I am marking the exact location of the shoulders using the leg.

That was followed by the same sequence involving the mitre box, router plane and careful chisel work to perfect the shoulders.

7/7/2017

So then on a crisp and bright winter’s Friday morning I started to flatten the bottom side of the top. Seeing that it is the first table top of this size in Kershout that I am doing by hand I thought that the bottom side would provide an ideal opportunity to work out which method works best. The major challenges posed by this top are the schizophrenogenic nature of grain and the extreme hardness of the wood. As every self-respecting JNSQ Woodworking reader should know by now, we deal almost exclusively with feral boards from the ancient Knysna forest. Each of the trees that the boards for this top were sawn from would have been over 500 years old.

If you deal with wood like that it is my opinion that one has a real responsibility to do the best possible job of allowing the story of the tree to be told. In my estimation that means a delicate balance between careful surface preparation and leaving certain imperfections that relates to the history of the piece of wood. George Nakashima’s immortal oeuvre of work (which inspired this design) lends itself perfectly to getting the most out of feral hardwood such as what I chose for this top. How much and which imperfections are left to tell the story is of course in the eye of the beholder.

Anyway, I started experimenting with various different tools to see what might work best in flattening such a challenging top. The techniques I tried included a belt sander, a low angle jack plane with a toothed blade, a standard no.3 smoothing plane (45° frog) with a back bevel of 25° creating an effective pitch of 70° and a shop made fore plane with a blade pitched at 50° (aka York pitch).

The belt sander has always been one of my least favourite tools. It makes noise, it is all over the place and seems to be the best possible tool to turn a flat surface into the famous Valley of a Thousand Hills. What I found was that it is less harmful in such hard wood, but still not an option if you are aiming for a superior surface. The low angle Jack plane (12° bedding angle + 38° micro bevel for an effective pitch of 50° and a tight throat) worked diagonally to the grain clearly had the measure of the wonky grain, but would have taken too long for what would suffice for the bottom side of the top. I did not aim for a perfectly flat bottom side.

Next up was the back-bevelled smoothing plane. It worked even better (in terms of finish) than the low angle plane, but was difficult to push due to the high effective pitch and therefore even slower at removing material. It is also important to mention that this strategie seize to be effective in difficult grain when you try to take a fat shaving.

So I rolled the dice and tried the shop made fore plane (50° effective pitch) diagonal across the grain. It wreaked havoc in a semi controlled sort of way. This particular blade has a fairly substantial camber and it took no prisoners in the process of removing the necessary material in a timely fashion. In the pictures below you can see the characteristic scalloped appearance of a surface smarting from such treatment.

This is one of my attempts at manipulating the photos to highlight the pattern left by the plane.

The wooden plane in the picture below enforced the above damage. Of note in the picture is the bottles of water I consumed during this arduous labour of bellicosity.

Here we have an example of a part of the history of the tree that is often neglected to be told. Yes I know some of you will think I have lost the plot. Probably something along the lines of: “The #%$@&* hippy has been smoking too much pot.” The reality for me is however that the wood I in my collection have all sorts of imperfections and it would be impossible to create anything of reasonable size without these imperfections exposing themselves. I have therefore made peace with having to incorporate imperfections and try to design in such a way that the eccentricity of the stock enhance the aesthetics of the piece I am building.

Here are a few more tweaked pics with an array of tools that were used to tidy up the bottom side of the top.

Then finally it became time to employ some of the lessons learnt on the bottom side to the face side of the top. It took me three full days of planing at 45° to the grain with a toothed blade in a low angle jack plane to get the top as flat as I wanted it. The two pictures below were taken after the first day.

The dogs on my assembly table came in quite handy during this brutal process.

The toothed blade created these beautiful patterns in the areas that were approaching flatness.

This was the end of day two.

14/8/2017

Once the entire (well almost) face side were in the same plane I removed the bulk of the rhombi left by the toothed blade using a no. 112 scraping plane. It was the first time I used this particular tool for a huge job like this. I prepared the blade the way that is recommended by my woodworking icon David Charlesworth. In my case a 45° main bevel, 50° polished micro bevel with a 75° burr set up in the plane with the blade leaning forward at 20°. The plane is an absolute joy to use when set up like this. You have to make sure you take very thin shavings of course. Some sanding with my shop made sanding planes took care of the rest of the rhombi.

While grappling with the rhombi I took short breaks to tidy up the cracks in the top. They all had lots of loose splinters of wood and other ancient bits of debris inhabiting their depths. This task was mainly accomplished by using a very old pocket knife that used to belong to my grandparents.

At this stage I shaped the curved ends of the top. As you can see I marked out two lines using my fingers as a fence. These lines guided the removal of waste to create a very gentle yet quite wide bevel. Once the bevel were established, the end grain area were rounded off ever so slightly using the same technique. My no. 9½ Stanley block plane did most of the donkey work and was then followed by a low angle smaller block plane, which was in turn followed by gentle sanding.

When I got a bit tired of the top I continued to chip away at the last bits of joinery.

Once the two aprons were fitted to the legs with very precise bridal joints, I started working on the massive beam that connects the legs at floor level. The Witpeer beam was laminated and squared up more than a year ago. It gave the wood a very generous time frame within which it could settle all possible disputes the fibres might care to raise (so to speak). It turns out that a very dense laminated beam like this stayed pretty much dead straight in all it’s  dimensions, but managed to go out of square by what appeared to be a full mm. That was fixed by hand planing a face side and face edge perfectly square with each other and using those reference surfaces to square up the others with my electric planer.

I transferred the inside measurements of the joinery from the aprons to the beam.

Using the above reference point I took the beam to the Windsor leg to mark out the exact location of the other side of the fairly complex stopped bridal joint (my own name not necessarily correct terminology) which will marry these two structures.

This is how far I got with this joint at present.

It was now time to break in my precious polissior that one of my favourite woodworking personalities and über craftsmen Don Williams (of The Barn on Whiterun fame) sent me earlier this year. That entailed rubbing the heads of the grass/straw on a rough piece of scrap wood and tidying up the appearance on a spindle sander.

I can thoroughly recommend reading Don’s article on this epic tool from the past.

Before.

After.

I used the Polissior to burnish the top after perfecting the finish with gradually increasing grid sander paper on a orbital sander. I went all the way to 600 grid and did two rounds of wiping the surface with a damp cloth to raise the grain before sanding it back down with the 600 grid. You can see the effect of the burnishing in the pictures below.

Aoife helped me to apply a tung oil/turpentine mixture. We kept the surface quite wet for 30 minutes by reapplying the mixture where the wood absorbed it and then wiped it down with a clean and dry cloth.

As you can see it was one of those unbelievably satisfying moments in woodworking where the wood rewards you for months of painstaking elbow grease. Kershout is simply one of the most beautiful species of wood on the planet. I want to reiterate that there were no pigment added what so ever. This is what it looks like after tung oil mixed with turps were applied!!

The top will now rest for two weeks before we will apply beeswax with the polissior. Stay tuned my brethren!!

My second commission – part 11

15/3/2017

As promised we will look into the process of jointing, gluing, and inserting dovetail keys into the top of the table in part eleven of our journey.

The rest of this particular chronicle can be found here.

The Kershout boards in the picture below were prepared up to this point towards the end of last year and has since been kicking it with my 1969 MGB in a separate garage.

The first task is to arrange the boards as best as you can with regards to colour matching and balancing out defects. This is where you whip out your artistic licence. This is after all a tribute to the legendary George Nakashima.

I took the opportunity to see what the trapezoid leg would add to the overall look. The top looks very light in colour (in this picture), but I can assure you that it will be transformed to a very dark reddish brown once the finish is applied. The Kershout dovetail keys contrasts exquisitely with the lighter Witpeer boards that makes up the trapezoid leg. I also like the darker lines created by the defects on the leg. It was strategically place to balance out from an aesthetic point of view. We will see later in this post how the reverse of the mentioned timber combination has a similar effect with regards to the top.

As you can see here my bench really came into it’s own working on the edges of these boards during the jointing process. I first prepared the edges so that they were close to the desired configuration, which is a very slight bow in the length.

Then the boards are clamped together with the two edges that will mate (so to speak) flush with each other and folded much like book-matched pieces before opening the “book”. This nifty trick leads to a cancelling out of the minute error that might arise in squareness of these edges with regards to each other. This technique is sometimes referred to as match planing.

Didi gave me a few pointers.

The Kershout is so ridiculously hard that I had to resort to using an alternating attack with my Lie-Nielsen low angle Jack plane armed with a toothed blade and a Shaw’s Patent Sargent no. 14C armed with an aggressively cambered blade.

Once the artillery softened up the enemy, I moved on to this shop made jointer plane to finish off the job.

I find my Festool Domino to be a very useful tool to keep the edges flush during glue-up.

It has become my custom to do only one of these edge joints at any one time given the short window to get the job done in our dry climate. Each joint is then left in the clamps for at least 16 hours. In other words, I tend to leave the glue-up for my final task each day. It is usually done at around 17h00 and left over night until around 09h00 the next morning.

Repeat.

Ditto.

Ready for the final glue-up.

I had to buy a set of 1.3m long 1″ pipes for my pipe clamps in order to do this final glue-up. Of course, as you would expect, my 1.2 meter wide assembly table was too narrow to accommodated the clamps for this glue-up. The situation therefore necessitated some problem solving on my behalf.

As you can see here a piece of wood (for each of the bottom clamps) was cantilevered off the edge of the table held in place by a clamp through a dog hole. Oh! … and yes, in case you wondered, it is my daughter’s “Biscuit finds a friend”. My English is not advanced enough to indulge in such haute literate.

As I have mentioned before, a mere mortal tends to sweat like a Gypsy with a mortgage during our sweltering rainy season. Didi is the master of African Climate Control (aka toplessness).

… and Bob’s your Uncle.

I modified the strip of wood that links my trammel points to draw a curve to soften the appearance of both ends of the top.

Marking the location of the dominos like this helps to remember where they are when further shaping is done.

The waste was removed with an electric jigsaw. It is a crappy old Black & Decker that I bought many moons ago while still living in New Zealand. I do not use it very often to start with and do not recall ever calling upon it to munch through Kershout. As most things you do for the first time there were a few lesson to be learnt. These things (for lack of a better insult) cut on the pull stroke, which translates into a messy splitting out of fibres at the top edge. Therefore (in hind sight) it is desirable to have the bottom of the top facing the jigsaw when doing this job. Secondly, I realised that I used a blade that was too aggressive, which did not help either.

On the flip side, this indiscretion coerced me into a design tweak that might (or might not) add an interesting twist. You will have to wait and see just like me.

Another reason I chose this shape for the ends of the top, is to enhance the appearance of it being sliced from a massive tree trunk. The idea is that this shape resembles the end of a trunk that was chopped off by axe. If you imagine a board cut from a trunk like the one in the first photo below, it would probably resemble the top of my table as seen in the picture below. That is in my mind anyway, you might feel different.

Then it became time to fashion a few dovetail keys to stabilise the obvious cracks in the top.

I worked out how many is needed of each size.

Here I tried to work out where to place the keys with regards to my sense of (randomly planned) artistic balance. The picture below was not the final version that was decided on, but somewhere towards getting there.

For the design of the keys I chose an angle of 9º, which repeats all through the design of the table. This is an idea you might want to consider. You draw only one key, chopped off at different lengths, and write on the template the number of keys needed of each length. It is then cut out, traced onto the wood as many times as the key tells you and then you chop off the ends and repeat on the next sized key. This way they all have the same shape, but of different lengths in an attempt to add visual interest.

As so.

The keys were liberated from the above Witpeer board by means of a bandsaw.

19/6/2017

Another useful trick is illustrated below. Clamping a piece of scrap wood across the top to hold the dovetail key firmly in place while it’s exact configuration gets marked out on the top.

Drilling out the waste by hand in such hard wood is no joke. “Trust you me”, as they say around these parts.

Enter: Lie-Nielsen merchandise in tandem with my trusty shop made Assegaai mallet. I chose the mallet as I needed a bit more heft than what the so-called Je ne sais quoi Persuader can deliver. When working “stone”, the extra heft is a must.

The lazy winter sun give us a better idea of the warm colours of the Kershout as it infiltrates my shop during the late afternoon.

It seems as if this post is riddled with tips, so here is another one. In order to see the scribe line better, one can have a small torch lying on the top to cast a shadow into the line. On my bench this is usually accomplished by positioning the bench light in a similar fashion, but clearly this top is too big to take to the bench.

Once the key enter it’s mortise like this I stop refining the fit. The key is then clobbered home after a frugal application of Epoxy, which acts as lubricant as well as an adhesive. The clobbering is done with a heavy mallet furnished with a thick sealskin face (not pictured).

As you can see here (minus the heavy mallet).

One week later the keys were planed flush using the two planes pictured.

As you can see the Witpeer keys contrasts nicely with the Kershout, much in the same way as the opposite combination works splendidly in the trapeziod leg.

We will get into the preparation of the top for finishing and the key bits of joinery in our next riveting edition of this series.

A Table for a shebeen – part 3

16/11/2016

The year is hurrying towards it’s inevitable end and the temperatures in my tropical haven are racing upwards at the same rate. The massive shift in ambient humidity that a good rainy season can induce always wind me up to get joinery that is supposed to last a really long time assembled during the driest part of the year. In my case that means before the end-of-year holidays, as the proper electric storm driven downpours tend to ignite a sudden hike in humidity around mid January. That is of course if we are lucky, because water has been in short supply in this sweltering savanna of ours.

For the purpose of this project I wanted to get the two leg-assemblies done before we leave for a hitherto tranquil spot on the Azanian south coast. Unfortunately the Zuptopian conglomerate has since done it’s utmost to “poison and destroy my brothers”, but let’s not dwell on the bane of my life while we could be discussing woodwork.

As discussed before, I prefer using Assegaai for my custom made drawbore pegs. I usually try and find a perfectly straight-grained piece before ripping strips on the table saw that are then fed to my Stanley no. 77 dowel making machine (not pictured). Unfortunately it is pretty much impossible to split (as apposed to rip) stock along the grain then using the no. 77 as you need perfectly square strips, but if you use fairly straight stuff it still turns out dowels that are far superior to the rubbish bought in local stores. I wrote in more detail on this process in previous posts.

img_7709img_7712

For the sake of trying something new I decided not to go with wedged through tenons as I did with the two workbenches that was built with similar sized stock. I am however partial to the idea of using wedges to ensure maximum strength. Therefore it was decided to experiment with wedges in a closed mortise. You will notice the kerf prepared for the wedge in the monstrous tenons. The sides of the mortise that needs to allow for the wedge to expand the tenon were adjusted. Then it is simply a matter of positioning the wedge in such a way that it sits in the entrance to the mentioned kerf while using pipe clamps to coerce the tendon into it’s mortise. That is of course followed by tapping the drawbore pegs home while the clamps are still in situ. The pictures below also show how I used my Festool Domino to cut the slots for the bits of wood that will fix the aprons to the top.

This was how the two leg-assemblies spent their festive season.

img_7713img_7714

16/1/2017

The drawbore pegs were then worked flush by sawing and hand planing.

IMG_7787IMG_7788IMG_7789IMG_7790

In order to mark out the exact location of the tenons of the two beams that link the two beams between the leg-assemblies (at an angle), I had to assemble the undercarriage.

IMG_7797IMG_7798IMG_7799

By clamping the linking beams at exactly the right angle, I was able to mark out the shoulders of the tenons.

IMG_7800IMG_7805IMG_7804

For some reason I found it very difficult to keep to the marked out lines while sawing away the waste by hand. It was the first time that I encountered this problem and still do not know exactly what was going on as I have done many similarly sized tenons in the same wood with the same saw?? Therefore I switched to the bandsaw for the rest of the work.

IMG_7806IMG_7807IMG_7808IMG_7809IMG_7810

I usually like to saw close to the line and hone in on it by planing the cheeks to a perfect fit.

IMG_7815IMG_7816

Marking out the location of the mortises.

IMG_7817

15/3/2017

Drilling out waste.

Removed the rest of the waste by vertical chopping.

Then it was time for the final glue-up of the undercarriage. I was very happy with how it came together and it sure is a robust construction.

The undercarriage received a few layers of Woodoc.

Before installing the undercarriage, the bottom of the top received a few layers of boiled linseed oil.

The pictures should do a better job than words to explain how the top was fix to the undercarriage.

Once that was done it became time to bring in some strength to get this baby to it’s feet.

Now I have to flatten the top by hand and trust me it looks a lot flatter than it is in the pictures below. I hope to complete this task before the end of the year.

My second commission – part 10

15/3/2017

My dear reader, I would like to apologise for my extended absence from the wonder world of virtual woodworking via the internet. You would find the reasons quite boring so let’s not waste any time nor effort ruminating on such drivel. This instalment of an apparently mammoth series will concern itself with the addition of the third and final layer of the so-called trapezoid leg. You can find earlier posts in this series here.

Seeing that the third layer would ultimately close up the internal workings of the whole construction, I took the opportunity to unscrew the second layer’s three ‘cross members’ (for lack of a better term). As you should be able to observe in the photos below, the old school mild steel wood screws received a coat of beeswax. This was accomplished by melting a block of wax in a small tin containing these traditional fasteners. The idea with this is that the wax should reduce the effort required to seat the screws and at the same time providing a layer that would resist future corrosion.

The screws were then seated after the surfaces that is supposed to be able to slide ever so slightly with the changes in ambient humidity over the years, were rubbed with beeswax. Whether this is useful (or possibly the opposite) I do not know, but I tried it anyway. Therefore I would urge you to ask someone who knows before following suite. Maybe some of our more experienced and properly trained cadres could assist in the matter.

Seeing that the plan was to fix the third and final layer using panel pins I had to fashion a custom punch to seat the nails below the surface of the wood. A short section of a round file which I picked up somewhere served perfectly well for this purpose. It was shaped carefully (not to take the temper out of the hardened steel) on a bench grinder to fit the head of the panel pin to a T. There are some picks further down to show the business end of my new redneck punch.

As is so common here in Africa, I also had to modify the panel pins somewhat to serve my purpose. In order to allow layer one and two to be able to move relative to each other, these panel pins had to stop short of layer one. In other words they should only fix layer three to the cross members of layer two. That was accomplished by snipping off the required amount, followed by resharpening on the bench grinder.

The two Kershout strips were fitted first, as they needed to be absolutely spot on given the fact that they mirror the spindles of the so-called Windsor leg. Kershout seems to enjoy spending time off  the Janka hardness charts (literally and figuratively) so it hard to say where it rates in comparison to better known species, but let’s just say it tends to take exception when a nail wants to upset it’s feng shui. For that reason I had to drill shank holes for each panel pin, which allowed the shank through and only caught the slightly wider head. This way the panel pins were more inclined to retain it’s linear configuration and the Kershout refrained from flexing it’s muscles.

As discussed in earlier posts, the third layer only needs to add another 8 mm for the trapezoid leg to reach it’s intended thickness of 44 mm. Therefore I decided to challenge my new bandsaw with fairly wide re-sawing in very hard Witpeer. Of course that also allowed me to introduce visual interest by means of a book-matched arrangement of the various pieces.

In order to do that I needed one flat, square and twist-free face side and face edge.

The resultant 8 mm stock were then fitted from the centre of the leg towards the outside. I again used the hitherto unproven technique of rubbing beeswax on the surfaces that is supposed to be able to slide.

I used a no. 78 and a no. 10 Stanley rabbet plane to cut the rabbets that hides the space allowed for movement.

The book-matched pattern is already vaguely apparent.

All the sides were then worked flush.

By hand plane along the grain …

… and by track saw followed by hand plane across the grain.

The small cavities created by seating the panel pins below the surface of the wood were filled with a concoction conjured up by mixing very fine wood dust (of the same wood of course) and epoxy.

Once the elixir had time to set I did a preliminary round of surface preparation.

As you can see the book-matched pattern is starting to emerge nicely. Once it receives oil it should be positively stunning.

Even the opposite side is starting to display a certain je ne sais quoi.

The edges were then treated to some hand beading to hide the laminations.

As you can see it worked a charm.

In our next instalment we will move on to laminating the various boards that was chosen (many moons ago) for the top.

My second commission – part 9

9/3/2017

This post disappeared from my site while it went into hiding. Here it is again for those of you who missed it.

Welcome back to JNSQ woodworking. Here is hoping that we will continue to share woodworking banter and ideas in 2017. This past weekend was my first back in the shop and it was a real joy. Much like 2016, my two main projects to focus on will be this so called “second commission” and the table for the shebeen.

7/11/2016

I will now report on the work done since our previous update in October of 2016. As usual just a quick reminder of what we are aiming for. A few shots of the model I built while developing the design.

IMG_6281IMG_6279IMG_6280

Something that I omitted to illustrate in the previous post is the techniques that were employed to ensure that the spindles end up with zero splay. The first method makes use of a device that we shall call the Tambotie gauge (as I used a small Tambotie off-cut to create this fantastic piece of equipment).

img_7628
The Tamboti gauge consists of an appropriately sized off-cut clamped to a square.

While reaming the mortises for the spindles you might remember how I made use of a stick with an appropriately sized tenon to check the rake angle.

img_7615img_7617

The Tambotie gauge is used to check that there is zero splay by comparing the gap between the Tambotie off-cut and the spindle on both sides, as referenced off the side of the beam with the square. In this case the spindle is leaning ever so slightly towards the right.

img_7630img_7631img_7632

Second of the two strategies again involves a highly complex jig that takes hours to build and set up. I clamped a winding stick to the side of the beam to check wether the spindle (positioned in it’s mortise) runs parallel to it, i.e. zero splay.

img_7638img_7639

Once all eight mortises received this treatment it was time to test how the assembly would fit together. As you can see it came together nicely.

img_7640img_7642img_7643img_7644

It is probably important to report on the stuff-up I made while drilling the pilot holes for the mentioned mortises. You might remember that I drilled one of these holes in the wrong direction and suffered from a Panic Attack subsequently. The solution I came up with was to turn a dowel of the same wood that fitted the hole perfectly and glued it into place. The hole was then drilled in the correct direction and the picture below show the result. There was only a small strip of the plug visible after drilling the new hole.

img_7641

After reaming out the mortise there was no evidence left of the blunder on the surface that would be exposed to critical eyes once the tenon gets glued into position. In the pictures below you can however see the edge of the plug inside the hole. Eish, that was a close call. Woodwork has a way of keeping you grounded, isn’t it.

img_7691img_7692img_7679

As these tenons run all the way through the beams, I decided to also wedge them. Here I am widening the mortise on the exit side to accommodate the wedges. I recommend reading Peter Galbert’s seminal work “Chairmaker’s Notebook” on how to orientate these spindles and wedges.

img_7681img_7680

Next up I had to  camouflage the laminations with a few carefully placed beads before glueing up the leg.

img_7683img_7684

I used my pre-1900 no. 66 Stanley beadingtool, which I restored quite some time ago. It takes elbow grease beading such incredibly hard wood, but it is very satisfying nonetheless.

img_7685img_7686img_7689img_7688img_7693img_7694img_7707

I think it accomplished what I intended as the beam now looks like a solid piece of timber.

img_7708

The tenons were then prepared to receive the wedges.

img_7727

Made some wedges …

img_7728img_7730img_7731

… and prepared for glue-up.

img_7732

I used a combination of mallet blows and clamps to coax the spindles into position.

img_7734img_7735

Once they were seated to my liking the wedges locked them down for ever (I hope).

img_7736img_7738

This is how the Windsor leg spent it’s December holidays, resting on the assembly table.

img_7739

16/1/2017

This past weekend I continued my assault on the so called Windsor leg. I clamped it to the trapezoid leg and used the latter to mark out the final shape of the former. This way they are exact copies of each other in terms of measurements.

IMG_7791IMG_7792

My daughter Aoife helped me to make the necessary cuts using my Miller’s Falls Langdon Mitre Box no. 75. It was quite a tricky operation given the awkward shape and size of the leg , but the Langdon made cutting the 9º angles straight forward.

IMG_7793IMG_7794

One day the student will become the master.

IMG_7796

The next big drama will be the third layer of wood that needs to be added to the trapezoid leg. I selected a good Witpeer (Apodytes dimidiata) board that ran pretty much through the centre of the tree and made a cut lengthwise along the pith. This gave me two quarter-sawn pieces. From these boards I then selected appropriate 800 mm chunks for re-sawing.  The idea with re-sawing is to created a book-matched pattern to the inside of this leg. This layer only needs to be about 8 mm thick to get the total thickness of the leg up to 44 mm, which fits perfectly into my  ratio of 22:44:66:88 mm (thickness) for the various parts of the table.

IMG_7811IMG_7812

You will notice the two strips of Kershout (Pterocelastrus tricuspidatus) on top of one of the piles of re-sawn and planed stock. We will use those to create a type of depth confusion for an observer viewing the table from the Windsor leg’s end. This will hopefully enhance the effect of an construction that defies gravity, but you (and unfortunately I) will have to wait until the next post to see how this works or possibly not?? Here’s hoping (that it works, that is)!

IMG_7813IMG_7814

A Table for a shebeen – part 2

20/10/2016

The title picture of this post is meant to remind you of what my shebeen looks like. The beautiful ensemble of chicks in the picture demonstrate how happy they can be around a stove. For fear of mass feminist hysteria, I will leave it at that.

It is a case of onwards and upwards with this project, which reminds me of something I have noticed in terms of my woodworking journey. Since about July this year I seem to have entered the next phase in my woodworking. It took the best part of 5 years to set up my shop in such a way that I can build furniture using a set of tools that suites me. That entailed lots of fairly small projects such as building various hand tools and jigs. There were of course also a smattering of mammoth projects such as building the two Roubo-esque workbenches, but it the predominance of small projects made it easy to blog regularly.

More recently however I have started working on projects that is destined to spread it’s wings and leave the shop for good (once finished of course). These projects seems to be more of a war of attrition than blitzkriegs, which makes it harder to find ways to blog regularly. As my friend Jonathan White (from The Bench Blog) usually say (and I am paraphrasing here),  posts should rather be infrequent than of substandard quality.

OK enough of my introspective reverie and on with our topic at hand. Didi and I managed to finish the stage of inserting the monstrous Kershout Dutchmen along the crack in the top. They were worked roughly flush with my shop made scrub plane. The top was then moved to the shebeen to keep it from getting wet when the rainy season arrive. I took great care to set up the sawhorses in such a way that the top would stay wind free.

img_7479img_7480img_7482img_7539img_7540

Luckily I checked with my winding sticks whether the aprons and stretchers were still wind free before continuing with the joinery. I found that they twisted slightly since being planed to perfection a few weeks prior. So back to the bench they went for some more remedial action. I find that my Lie-Nielsen low angle Jack plane with it’s toothed blade works well where you encounter significant knots like in this case.

img_7542img_7552img_7554img_7555img_7557

The mortises were then marked out and the waste removed with a spade bit driven by an electrivore.

img_7560

In this case the eletrivore was assisted by a carnivore, which is inevitable being resident in Namibia for several years. Vegetarianism (vegans are already extinct here) appears to be illegal (and omnivorous creatures should not get too cosy either) in this fair land and ‘vegetables‘ is certainly a most deplorable swear word.

img_7563img_7564

25/10/2016

The rest of the waste were chopped out using chisels and a hammer.

img_7572img_7578img_7579img_7580img_7566img_7567img_7568img_7569img_7570img_7571

Next up were the two beams that connect the two leg assemblies.

img_7598
This is what the shop floor looks like after serious hand planing (in 35 degrees celsius weather I might add).

img_7591img_7592img_7601img_7602img_7603img_7605img_7606img_7607img_7608

Aoife came for a visit to the shop and took some photos. Her right hand is not nearly back to normal (after the drama we had in February), but managed to get a few in focus.

img_7646img_7653img_7656img_7659

These long beams slot into each apron/stretcher with a type of cross lap joint. In the pictures below I am marking out the exact location of the slot in the stretcher/apron.

img_7660img_7662img_7663img_7664

Followed by cutting the slot, …

img_7669img_7672img_7674img_7675img_7671img_7676

… which allows the two parts to lock together.

img_7678

I then drilled the holes for the drawbore pegs. As you might remember I like producing my own custom dowels for this purposed. I prefer using Assegaai (Curtisia dentata) for this as it has all the ideal properties. I use a Stanley no. 77 dowel machine with a ½” cutter head. In the pictures below I am using a ½” brad point drill bit to mark the exact location of the holes in the leg on the tenons of the stretcher/aprons. This mark can then be used to offset the hole through the tenon. Basically you move the hole through the tenon a smidgen closer to the shoulder, which allows the peg to draw the tenon into the mortise when it is driven home.

img_7696img_7697img_7699

In these pictures I am busy chamfering the edges of the legs using two block planes. The one is tune to take heavy shavings and the other for very light shavings. The bulk of the timber is removed with the heavy cuts followed by a few fine cuts to leave a perfect surface. I simply run two lines parallel to the edge and plane to the line. Doing this task by hand is one of the most therapeutic in my experience.

img_7700img_7702img_7706img_7703img_7704

My second commission – part 8

20/10/2016

We finally arrive at the stage of this project that has generated the most anxiety for me. It will be my first attempt at using Windsor technology in any piece of furniture. As you know from the previous posts in this series I have completed the bulk of the so called trapezoid leg, so now we need to grapple with the so called Windsor leg. The rest of the table was inspired by (and leans heavily on) the work of George Nakashima, but this leg is entirely my creation. Having said that I am quite sure there would be similar designs out there, but it was not something I can remember seeing on the net during my research phase.

The idea with this design in general is that it suites the feral nature of the wood I have available. As most of you probably know, Nakashima was a master in the art of allowing the wood to speak for itself. The idea behind this particular leg is to create an elegant counterpoint to the otherwise rugged robustness of the design. It is meant to establish a sense of the top deceiving gravity. In other words, I wanted it to appear as if the top is floating in mid air. There will be a few more details added to the inside of the trapezoid leg to further enhance the mentioned effect, but for that you will have wait.

IMG_6279
A quick reminder of what we are aiming for, a few pics of the prototype.

IMG_6282IMG_6283

As you might remember the Kershout beams that will form the top and the bottom of the Windsor leg were laminated previously. My first step thus, was to square up a face and an edge by hand planing. I included the monstrous beam that runs between the two legs (at floor level) in this process as it has exactly the same dimensions i.e. 66 mm x 88 mm.

img_7445img_7446

The electric planer then leached off my elbow grease to flatten the opposite sides of the beams.

The spindles presented the first major challenge. I did not want to laminate stock for the spindles as it would be very obvious in the final product. As I discussed earlier in this post these spindles also need to be elegant, which are the two main reasons why I prepared Kershout stock in the order of 1″ (25 mm) x 1″. As you can see the square stock was first planed into an octagon-shaped spindle, before it was introduced to the lathe.

The major challenge of turning these spindles was that I purposefully kept them ever so slightly bowed (lengthwise) as it would aid in turning more natural looking bamboos. Yes Bamboos. I want these spindles to look like bamboos to fit in with the Japanese theme of the table’s design, as well as the feral nature of the timber that was chosen.

That of course is no drama at all, but as anyone knows who’s tried to turn off centre work it is not a joke. You add to that the Kershout characteristic of being ridiculously hard and you have yourself a full-blown drama.

In the end I was forced to use 60 grid sandpaper to do the rounding as every other more conventional technique wanted to rip big chunks of timber out at the fat end of the bow (if you see what I am saying).

As you would expect, while rounding off the last of the four spindles I found that this particular one had an area where the grain developed a brief psychotic episode, which would have compromised the strength of it. Given the delicate nature of the design I could not risk any weakness to one of these four spindles, which meant that I had to start from scratch with fresh stock.

Once all the spindles were round and passed the grain-reading/strength test I marked out the location of the tenons and Bamboo’s nodes. As you can see I used the trapezoid leg as a guide seeing that the Windsor leg will mirror it’s shape. The angle of the spindles is exactly the same as the sides of the trapezoid leg i.e. 9º. The nodes were placed in such a way that the different sets of nodes (across the 4 spindles)  will form (partly invisible) chevrons pointing upwards. The chevrons are at 9º in relation to a line that run perpendicular to the spindle. Now that sounds very confusing, but it is the best my grasp of the English language will allow for.

Once all that was done I had to take the plunge and try to shape natural looking bamboos from spindles that is neither completely round nor completely straight. First, I very carefully placed the nodes using a skew lathe tool. After that I used 60 grid sandpaper to hollow out the internode segments ever so slightly. I purposefully made no attempt to shape them exactly the same. This was a deliberate ploy to have it looking more natural. Unfortunately attempts at making stuff look natural often ends up with it looking tacky, which was one of my main concerns. Luckily it came out looking reasonably good.

In this picture you can see how the slight bow in the length of the spindle made the nodes asymmetrical (for lack of a better term). The node is clearly much deeper on the left hand side than the right. This together with the slight inconsistency in shape and thickness of the internodal segments contributed to the natural look of the bamboos. Oh yes, that and the fact that the spindles are not completely round all over.

Once all four of the spindles were roughly shaped, they went back to the lathe for finishing (sanding with progressively higher grid sandpaper) and the shaping of the tendons.

At last it was time to use a set of hand tools I made back in January. I am of course referring to my shop made Reamer and tenon cutter.

As you can see here I again used the trapezoid leg to position the two beams of the Windsor leg before marking out the location and angle of the mortises.

It all went swimmingly as I first drilled pilot holes on the drill press to keep the spade bit that followed honest. Unfortunately I decided to drill these pilot holes out (with the spade bit) at the end of a very long Saturday. The concentration was going south and it ended up with me drilling one of the holes in the wrong direction!!!!

Enter: Panic Attack! #@!$^%*(&^&*%#@%^!!!!!

Seeing that this is not the first stuff-up I have made in the shop, I know that it is better to just stop working and try to calm down. In this case I added an ice cold G&T to treat the acute exacerbation of my Anxiety Disorder. After my rational mind retuned, it became quite clear how to fix the indiscretion. I had to turn a piece of Kershout to the exact diameter of the hole and glue it into place.

Let this be a lesson to all of us, stop working when you get tired (or gatvol as we would say in this part of the world).

The next day I was able to plane the fix flat and drill a new hole, this time in the correct direction. After that I got to play with the second of my two shop made tools, the reamer.

I drew a square around the hole before I started reaming. This helps to give a visual guide of the progress and alignment.
