Petite Wooden Smoothing Plane

 

I have been reading about and planing to make my own wooden planes for about a year now. I first thought of the idea when I realised how expensive it is to order good quality planes from the USA. For every two Lie-Nielsen planes I pay for an extra one in shipment fees. Make no mistake, the people at Lie-Nielsen have the best customer service I have ever come across and as everyone knows their planes are superb. Yet, sending it half way around the globe costs money.

The more I read about the wooden versions, the more it sounded like they might almost be better than their heftier cousins. Being a bit of a traditionalist, the idea of building my own wooden planes started to gain some momentum. I then had discussions with Deneb Puchalski of Lie-Nielsen around which blades might be best for the types of planes I wanted to build. He was very helpful and in the end I decided on:

1) Three x 2″ wide standard blades with chipbreakers (25 degree primary bevel)

 

2) One 1¾” wide standard blade with chipbreakers (25 degree primary bevel)

 

3) One Scrub plane replacement blade 1½” x 3/16 (thick)

 

4) One large shoulder plane replacement blade 1¼” x 8¼” x 0.140″ (thick)
The blades arrived on the 11th of June 2013 at which time I started to hunt down beech. Surprisingly, I found some in the Land of the Brave. I decided to first build a smoother and a scrub plane to warmup.
In the pictures below you can see the first chunk of beech after it received attention from the planer.

At this point in time I still did not rehabilitate my bandsaw (thus not able to re-saw at all and definitely not ysterhout in any dimension approaching what was needed), so I had to plane a fairly small piece of ysterhout down to about 8 mm thickness (from about 24 mm). I wanted to use this incredibly hard wood for the soles of my planes. In the pictures below you can see how I used the bandsaw to cut the sole of the smoother.

IMG_6932IMG_6933

After studying the grain of the beech I decided to laminate it as you can see in the pictures below. It is impossible to find beech in bigger dimensions (around these parts) so lamination was my only option. Speeaking of which, I can really recommend the documents on building wooden planes written by Larry Williams and his partner at Old Street Tools. You will find the link on the library page of this site. There are articles on grain orientation, best woods to use etc etc.

Here you can see how I laminated the parts.

IMG_6937IMG_6938IMG_6939IMG_6940

For some or other reason I decided to stick it in the face vise, which is not the best as the two jaws are not completely parallel, and I have made this mistake before. Anyway, it came out OK, but I really need to stop doing this.

IMG_6943IMG_6944

Next step was to hand plane the sides dead flat and square to the sole. You can appreciate the beautiful soft shavings generated by my newly rehabilitated Stanley no.5 Jack Plane. I wrote a complete post on this project which you can find in the category by the name of “Rehabilitation of old tools”.

IMG_7010IMG_7007IMG_7012

In order to make the next cut I was forced to spend most of the next week trying to fix and tuneup my old crappy bandsaw. The results however made it well worth my while. After the tune-up it sliced such perfect strips off the side that it only took a few strokes with the plane to get them as smooth as a baby’s bottom …

IMG_7031IMG_7024IMG_7032

… as you can see here.

IMG_7133IMG_7134IMG_7135IMG_7136

I then used the planer/thicknesser to get the inside close to the correct width. Maybe a bit less than 3 mm wider than the width of the blade. For this Petite Smoother I chose the 1¾” blade.

IMG_7142

 

Here you can see how I marked out the bedding angle at 51º (just to be different of course).

IMG_7144IMG_7145

In order to make this next cut I had to build a jig for my bandsaw. I call it a “Bandsaw Mitre-sled”. You can find and read an entire post on this project under the above name …

IMG_7146IMG_7147IMG_7148IMG_7149

… here you can see the actual cut.

IMG_7150IMG_7151IMG_7152IMG_7153

In the first picture you can see the toe and heel section after the first cut. In the next pictures you can appreciate the curve that was cut in the toe section.

IMG_7154IMG_7156IMG_7157

I used the Green Monster to smooth the curved surface of the toe section.

IMG_7158IMG_7159

In order to prevent blowout of the Ysterhout sole while planing the so called ramp, I used the wedge (off-cut) that was created by the two cuts made earlier. You can see how I clamped it in the legvise to support the fibers on the delicate edge of the sole.

IMG_7167IMG_7168IMG_7169IMG_7170IMG_7169IMG_7171

 

After getting rid of the saw marks left by the bandsaw by means of the old Stanley Jack Plane I used the 3M Adhesive-backed sandpaper on a sheet of float glass to get it 100% flat. You will note the technique I use frequently in scribbling on the area with a 2B pencil before sanding to identify the areas that needs more attention. Once all the pencil marks disappear you know the job is done.

IMG_7172IMG_7173IMG_7174IMG_7175IMG_7177

 

The next step is to start marking out the position of the toe and heel sections relative to each other. I started by marking out the position of the toe piece and clamping it into this position.

IMG_7181IMG_7182

 

For the next step it is useful to have the blade in it’s position on the heel section, also known as the ramp. In the second picture you might just be able to see the line I marked at 1.5 mm parallel to the sole on the toe section. The idea is to line the cutting edge of the blade up with this line as demonstrated in the second picture. This tells you were the heel section should be relative to the toe section. You then remove the blade and mark the position with a pencil.

IMG_7183IMG_7184

 

In the first two pictures below you can see where I marked out the perimeters of the cap-screw slot. The off-cut wedge is again priceless to create a big enough surface in order to cut the slot with a router as shown. Please note the makeshift stop I’ve setup on the left hand side.

IMG_7185IMG_7186IMG_7187IMG_7188IMG_7189IMG_7190IMG_7191IMG_7192IMG_7193

 

Just a quick test to see whether the slot functions as planed.

IMG_7196IMG_7197IMG_7198

 

In order to drill the second of the cross-pin holes you need to clamp the whole shebang together after drilling the one side in the correct spot. You will find a host of different ways to identify this point on the internet. I used the measurements provided in an article titled “Wood Planes made easy” by David Finck in Fine Woodworking Magazine. Once I clamped it all into position I tapped some minute panel pins into each corner to ensure that I could put it all back together exactly in the same way during the glueing phase.

IMG_7199IMG_7200IMG_7207IMG_7210IMG_7208IMG_7212IMG_7215

 

The idea is then to stick the drill bit through the existing hole to drill the opposing hole exactly in the correct place using a perfectly square drill press setup as shown.

IMG_7204IMG_7206

 

The cross-pin was created by milling a scrap piece of Assegaai down to a ½” square strip that was much longer than needed. In the pictures you can see how I removed some stock by means of the table saw to start shaping the pins on either side. In future I would rather do this with my Lie-Nielsen carcass saw. In the next few picture you can see how I shaped the pins with a file.

IMG_7202IMG_7203IMG_7216IMG_7217IMG_7220IMG_7221IMG_7222IMG_7223

 

To make sure that everything fitted perfectly I did a dry fit as shown.

IMG_7224IMG_7225IMG_7226IMG_7228

Then I shaped the cross-pin further by using this setup.

IMG_7230

The glue-up is fairly straightforward due to the panel pins that ensures that it all comes together precisely how it was previously decided. Please note the caul clamped to the sole area to ensure that it ends up perfectly aligned.

IMG_7231IMG_7232IMG_7234IMG_7236

The cross-pins were then trimmed flush.

IMG_7273IMG_7274

Next step was to shape the plane and I started by cutting the ends containing the panel pins away.

IMG_7275IMG_7277

Then I marked out this funky curvy configuration on the ysterhout sole. The reason for doing this on the sole was that I wanted to have the sole at the top while cutting the curves on the bandsaw to prevent blowout of the rocklike yet brittle ysterhout. In the second picture you can see the result of the bandsaw’s caress.

IMG_7278IMG_7279

The bandsaw marks were removed by a series of steps including the use of a float, a smoothing plane and finally various grids of sandpaper on float glass. The result was staggeringly beautiful to say the least.

IMG_7280IMG_7282IMG_7284IMG_7285

The piece of Tamboti you see in the pictures below is the only one I have left and a board I know as long as I can remember. I thought that this was the ideal place to use such a priceless piece of timber. I decided to produce the wedge of this sexy petite plane using Tamboti.

IMG_7316IMG_7317

Here you can see the wedge in it’s early stages.

IMG_7318IMG_7319

The next step was to decorate the plane further with some sexy stopped chamfers. I marked it out by hand using a pencil and my finger as a fence. You can probably see that I deliberately did not do a 45º chamfer, but rather one that further complements the elegant elongated shape of the plane.

IMG_7320IMG_7321IMG_7322IMG_7323

Using the pencil lines as guides I used a small Lie-Nielsen block plane, a file and my Proletarian Sanding Contrivance to create the chamfers.

IMG_7324IMG_7325IMG_7326

Then I moved on to flattening the sole. It is important to tap the wedge into position at about the same tension as it would be while being used, before attempting to flatten the sole. The pressure from the wedge deforms the sole ever so slightly so the idea is to flatten it in the shape it will assume while the wedge is tapped into place. You can see that I once again scribbled on the sole prior to flattening in order to identify when it is completely flat.

IMG_7329IMG_7330IMG_7331IMG_7332IMG_7336

In order to custom-fit the wedge I dialed in the width by planing down the sides with my rehabilitated old Stanley no.4 Smoother. Apparently one should be careful not to make the wedge too tight-fitting as far as the wedge goes as it can damage the plane if it expands during humid months. I therefore made it about 3 mm narrower than the ramp. In the last of these three pictures you can see the plane hammer I built to set the plane. You will find an entire post devoted to this project under the category “Handtools”.

IMG_7333IMG_7334IMG_7335

I sharpened the Lie-Nielsen blade to have a cambered edge.

IMG_7337

I took to a small piece of swarthout to test the little beauty and the results were incredible. It gave the best finish I have ever seen and the shavings were extremely thin and soft. There were not even a hint of chatter. What also surprised me was how easy it is to set the blade with the small plane hammer. It almost felt easier than setting a cast iron plane.

IMG_7338IMG_7339IMG_7340IMG_7341IMG_7353IMG_7351IMG_7349

Here are two photos to show off the beautiful Lie-Nielsen iron-chipbreaker set.

IMG_7344IMG_7343

Part of the success of this little plane must be the tight mouth. In these pictures you can also appreciate the je ne sais quoi of the ysterhout sole.

IMG_7345IMG_7346IMG_7347

Finally a few pictures of the plane in the late afternoon sun after a light coat of Ballistol. I plan to treat the sole with wax once I find a suitable product.

IMG_7465IMG_7469IMG_7466IMG_7467IMG_7468

 

4/9/2013 – I finally got round to treating this little beauty after using it for a few weeks. You can see how it joined it’s bigger cousin at the Finishing Spa.

IMG_7916IMG_7917IMG_7920

 

Here are a few final photos of a little plane that has already become a go-to tool in my shop within the space a month.

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.

IMG_5814IMG_5815

 

Tamboti-red_MAR5443_IJFR A beautiful Tamboti tree in the wild.

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.
