My 18th Century Workbench in progress 28

16/2/2015

This was one of those weekends in the shop were I did not feel I got much done despite working almost 2½ days. I am still busy with the two sliding deadmen for my bench. One of them will double up as a sliding leg vise, a la plate 279 of “L’Art du Menuisier” (pictured below). Mine however, will be on a smaller scale and retains it’s deadman anatomy too. The point being, this is slow and fiddly type work.

Cutting the thread for the wooden screw.

One Assegaai wooden screw being cut. This antique German screw box is frighteningly sharp. It felt like I was cutting custard.

Here I started working on the leg vise’s jaw.

IMG_3242IMG_3243IMG_3244IMG_3245IMG_3246

Each deadman has a base which slides on top of the bench’s long stretchers. The joinery is a complete overkill (as per usual). It includes, through mortises that were wedged and draw bored. As you might gather from the pictures, I experimented with slow setting epoxy and normal PVA wood glue for the draw pins. The epoxy, which has a consistency similar to vaseline, certainly improves the ease of clobbering them home. I think it has to do with the fact that it acts as a lubricant and also does now lead to immediate swelling of the dowel, which is the case with the water based glue.

The protruding tenons and wedges were worked flush by passing it over the table saw several times followed by paring. The surfaces which will be in contact with the top of the stretcher were then covered with sealskin.

I simply do not have the technical vocabulary to describe what I did here. The pictures will have to tell the story.

IMG_3280IMG_3270IMG_3271IMG_3275IMG_3276

Just to be different, I decided to use an eggbeater drill as inspiration for an alternative looking sliding-deaman-leg-vise. With a bit of imagination, you will probably be able to deduct where this is heading.

IMG_3272IMG_3273IMG_3274IMG_3277IMG_3278IMG_3279

This is a very handy idea if one wants to shape and sand small round parts. This piece is destined for the eggbeater-leg-vise-deadman.

OK, one more clue dressed in sealskin.

Epoxy tip

I find that 99% of the time I need minute amounts of Epoxy at any one time. Seeing that Epoxy is not as easy to cleanup as PVA glue I came up with the idea to mix these smatterings of adhesive in  soft drink bottle caps. In the pictures below you can see how I collect some in an empty water bottle for this purpose.

IMG_7088IMG_7089

In the example below I used a beer bottle cap. I throw the caps away after use, which eliminates the needs to clean up.

Old Stanley Bailey handplane rehabilitation

My father gave me most of his tools some years ago when he decided to downscale and pursue other interests. He was very much a powertool woodworker as apposed to a hybrid woodworker (someone who uses both hand tools and power tools) or a handtool woodworker. I never even knew that he was as his way was the only way I knew, until I started reading American woodworking magazines and listening to podcasts such as the one by the Modern Woodworkers Association (my favourite) and Wood Talk (highly recommended). Now I realise that there are other ways to approach woodworking conundrums.

It is not as if I am not grateful for everything I learnt from my Dad, as it certainly got me hooked to woodworking in a big way, but I am finding myself gravitating towards quality handtools with a vengeance. I guess that would make me a hybrid woodworker with fairly basic handtool skills at present.

This is really a roundabout way to get onto the primary purpose of this post, which is the rehabilitation of the two old Bailey handplanes my Dad handed down to me. It is a no. 4 Smoothing Plane and no.5 Jack Plane that really needed serious attention. I never even knew that one should sharpen the plane irons as my father and I never did. Probably, in hind sight, because we never used them. For this reason they never seem to work very well, which did not encourage any further scrutiny.

That was until I watched the DVD on Plane Sharpening by David Charlesworth and using a sharp Lie-Nielsen No.4½ Smoother. It would not be too much of an exaggeration to say that it was an epiphany. A sharp handplane is poetry in motion. It is psychotherapy for a shrink … literally in my case. David also explains very clearly in his DVD what comprises a functional and well tuned (apart from a sharp iron) handplane, which is all very useful to any woodworker, but especially to plane rehabilitators.

Armed with this new knowledge I set about to rehabilitate these family heirlooms. In the first few pictures you can get an idea of the state they were in. It used to be toilsome to slice Parmesan cheese with these planes, to be honest.

100_1202100_1203100_1204IMG_6814

First step was to flatten the soles of these planes and it turned out that they were in some serious need of this particular ministration. An added bonus of doing this is that it makes the shiny parts of the plane body smile with a rewarding gleam. I have to warn you that this is hard work that can take time and perseverance from a woodworker. You do not have to get it 100%, but the toe, the area behind the mouth and a reasonably large area towards or at the heel all needs to be in the same plane.

A Magic Marker is very useful to demonstrate the areas that needs attention. Drawing a grid (as shown) before taking a few swipes over wet-and-dry-sandpaper fixed to 10 mm thick float glass, would reveal the troublesome spots in no time. Please note that I left the plane irons clamped in their usual position, only making sure that they are retracted well into the plane body in order not to get damaged by the flattening activity. The reason behind this is that the clamping action of the lever cap deforms the sole ever so slightly which means that you want to flatten it while under tension.

IMG_6812IMG_6813

The remnants of gridlines clearly indicate the low lying areas as seen below.

IMG_6815IMG_6816IMG_6817

Then it becomes a question of elbow grease, burning some midnight oil or whatever it might be called. Here you can see how I used my sharpening jig to do the flattening. If you want to read the post on how I made this jig find the post called “My version of Deneb’s sharpening jig” under the category “Jigs”. This jig clamps wet-and-dry sandpaper on a piece of float glass by means of two cauls.

IMG_6818IMG_6819IMG_6820IMG_6821IMG_6822

The final product is well worth the effort I thought.

IMG_6823

Next I took the planes apart completely, including removing the plane irons with their chipbreakers, the frogs, the totes and knobs.

IMG_6824IMG_6825IMG_6826IMG_6827IMG_6829

Here you can see how I sharpened the new replacement blades I bought from Lie-Nielsen. If you are interested in purchasing replacement blades for old Stanleys, check out Lie-Nielsen’s website, they have the whole range. Their blades are definitely the business. Their blades are prepared at a primary bevel angle of 25º and ground flat as … oh no just remembered this is a family website … but you really do not have to do too much work on the back at all.

I honed a 33° honing angle on my 1000 grid Ohishi waterstone and polished a 35º final cutting angle on a 10 000 grid Ohishi stone. Both blades were sharpened with a cambered edge.

In the picture below you can see the Nagura stone I use with the 10 000 grid stone.

IMG_6835

Here you can see how the totes and knobs looked like prior to rehabilitation. Clearly some type of varnish left that was starting to look seriously weathered. I removed the the varnish with a card scraper before tidying it up with sandpaper.

IMG_6836IMG_6837IMG_6838IMG_6840

A last picture before the frogs came off.

IMG_6841

The two screws that fix the frog to the body of the plane is evident in the first picture. In the third picture you can see the screw that helps you position the frog during reassembly depending on how tight you want the throat.

IMG_6842IMG_6843IMG_6845

Next step was to carefully remove the worst of the rust from the frog’s surface that supports the blade with a fine flat file.

IMG_6846IMG_6848IMG_6849IMG_6850

In the first picture below you can see how I then used a magic marker to blacken all the surfaces that is in contact with the back of the blade. In the next picture you can see the setup I used with 150 grid wet-and-dry sandpaper on a piece of float glass on the edge of the table in order to easily hone the most important front section of the frog. In the third picture you can see how the leftover magic marker indicates the areas that needs more attention after just a few strokes on the sandpaper. The last picture show how it is all cleaned up and flat as … yes you know what I mean.

IMG_6851IMG_6852IMG_6853IMG_6855

Here you can see how I cleaned up and flattened the areas of the frog that is in contact with the plane body.

IMG_6856

Speaking of plane bodies, here you can see how they look prior to a Ballistol treatment.

IMG_6857

One of the most important parts of this rehabilitation operation is the work done on the chipbreakers. You want to flatten the area in contact with the blade at an angle that will ensure that the absolute tip of the chipbreaker sits flat on the back of the blade. This is accomplished by the setup as shown. You can see how the angle created will ensure that only the tip ends up flat on the blade.

IMG_6861IMG_6858IMG_6859

Here you can see how I decreased the angle slightly for honing and polishing. In the last picture you might be able to appreciate the perfectly polished and flat area that will ultimately sit on the back of the blade.

IMG_6863IMG_6864IMG_6862

The lever cap being made of cast iron is much easier to flatten, but again remember to set it up so that you only flatten the area that matters at the very tip that will be in contact with the chipbreaker. These lever caps were not even close to flat in the mentioned area.

IMG_6865IMG_6866

Here you can see the totes and knobs before and after a Ballistol treatment.

IMG_6867

Both totes were very wobbly due to very slack tolerance around the two raised cast iron areas on the base. I decided to remedy this by inserting some Epoxy putty and squeeze the tote into position, in order to create a perfect fit.

IMG_6871IMG_6872IMG_6873IMG_6874IMG_6875IMG_6877

Finally all the parts were reassembled with the frogs set up to create a very tight throat on both planes. I can really recommend doing this for those of you who do not mind some elbow grease in return for a pleasing precision tool. There can be no comparison between how these planes cut post rehabilitation compared with prior to it. It is an absolute pleasure.

IMG_6878IMG_6879IMG_6880IMG_6881IMG_6882IMG_6883

 

As per usual, the proof is in the pudding. Here are some of the first shavings I took. It is poetry, I tell you!

IMG_7096

I think they are ready for another few hundred years of work.

Tamboti and Witels marking knives

Marking knives are one of those multifarious paraphernalia that have not made it’s merry way to the distant shores of Namibia. Seeing that it is a fairly vital tool in a proper woodworking workshop, I had to make a plan.

First, I set off to find some reasonable steel for the project. I decided to use the blade of an old Bailey no.4 hand plane of my Dad that I am busy revitalizing. There are some Lie-Nielsen custom replacement blades on it’s way to me as we speak to replace this particular blade. Anyway, so the steel was sorted. Then I had a good ferret around for suitable off-cuts of wood for the handles.

Finally, I decided on some Tamboti (Spirostachys africana) and Witels (Playlophus trifoliatus). I only have two very small pieces of Tamboti that have probably traveled more than 2000 km over 15 odd years with my father and already 1800 km over 13 years with me. Maybe it is time to do something with it. The first two pictures below show the old plane blade on the Witels wood. The copper ring you spot is one of those the plumbers use to join copper pipes. Clearly I need to improvise and use what is available.

You will usually find these gargantuan Witels trees in the wettest parts of the forest.

In the next few pictures you can see the small piece of Tamboti. I deliberately chose to cut a blank that contains a bit of sapwood to show off the beautiful colour contrast. These blanks were so small that I had to improvise again in order to fit it on my antediluvian lathe. You can see the plywood wheel with a recessed area accepting the blank that is screwed to a bigger piece of hardwood. Yes it is fiddly to say the least.

IMG_5816IMG_5817IMG_5818IMG_5819

Here you can see the turned Tamboti handle. The sapwood really adds some je ne sais quoi, don’t you think? You can also see the part of the blade allocated to this particular knife. The front part of the handle is turn to be a fraction bigger than the hole through the copper ring, but with absolute end slightly smaller to get it going when tapping it over with the blade in place. A take-home message from turning this blank, is to look for wood that has fairly straight gain throughout. The haphazard gain pattern on the front of this blank looks nice but does compromise it’s strength somewhat.

IMG_5821IMG_5822IMG_5823

Below you can see the Witels blank being shaped on the lathe. This was the first time I have turned Witels and only the second time I have worked with it at all. In hindsight it is probably not the best wood for this application as it is very porous and softer than what I am used to if compare to Assegaai (my go-to wood for tool making). Nonetheless I do not think there are too many people with Tamboti and Witels marking knifes.

IMG_5834IMG_5835

Unfortunately I did not take pictures of how I shaped the the blade or the internal design of how it was fitted to the handle. Therefore I made some crude Sketchup drawings to give you an idea.

You can clearly see the shape of the blade. It has a thin shaft that was inserted into the hole drilled down the middle of the handle. That part of the shaping was done by cutting it roughly to size with a grinder and finished off with hand files. The front of the blade however took ages as I did not want to overheat the steel and lose the temper. Therefore it was done slowly over hours with water stones and wet-and-dry sanding paper. Part of the blade was seated inside a slot cut into the front part of the handle, which clamped down on it when the copper ring was tapped over that section of wood. I also use epoxy to help fix the blade to the hilt (if you pardon the pun). It was inserted down the shaft’s hole, as well as inside the slot. Something that worked very well was the epoxy on the wood that came into contact with the inside of the copper ring reduced the friction significantly while tapping it over.

Here you can see the final product. The Tamboti knife has a fairly short blade for all the run-of-the-mill work. The Witels knife has a blade almost double the length of the first and also sports a slightly more Brobdingnagian handle.
