I’m working on a few things at once; including another wainscot chair. Making the “rake” to the rear legs is the largest output of labor for a single piece of wood in my repertoire. And, the most conspicuous waste of material. But, it has to be done. I rived this white oak billet about 3 1/2″-4″ square, maybe 45″ long or so. I start then by hewing the tangential plane into something close to flat.
This is a departure from my standard practice – I usually always work the radial face first. It’s easiest to plane, and often rives quite flat. But in this case, I’m planing the side-plane of the rear post – so I can then layout the shape on this face. If you enlarge the photo below, you can see the growth ring orientation on the end grain.
Each wainscot chair I have seen is different in its angle/rake/cant – what ever we might call the shape hewn and planed above the seat. I like to align the top end with the grain – it makes plowing the panel groove easier. Chopping mortises too. But to do this, like in the photo below, it means the chunk of wood to give you this shape is pretty hefty. This particular chair isn’t raked all that much…some have a greater angle than this.
There have been times when I have shifted the template on the stock, to squeak the leg out of a thinner piece of wood. To do that, you bump it so the leg angles back both above and below the seat. Sometimes a riven piece of wood will have some blowout here or there so you have no choice but to do this. The downside is all the joinery is mis-aligned with the fibers of the wood. There’s no way around that to some degree, but the orientation in the first photo minimizes it.
After having determined the layout, I hew off the bottom/front and then bring the piece to the bench to plane the top front face. This is the radial face. On this chair, the surface will be carved.
Once I’ve planed the top and bottom front face (the top & bottom here are in relation to the seat height – above and below the seat.) Then I mark the thickness on the side view, and saw a relief cut from the back, at the point where the leg angles back. This is the same height as the top of the seat rails. But that’s later.
Now – depending on how straight the wood is, how tough your nerves are – you can rive off the bulk of that waste. I knocked the froe in, but left a chunk of wood for caution.
I jammed it in the riving brake, and it split as perfect as can be. It popped off right after I took this photo. Almost hit the camera.
I had left some wood that needed hewing; I did the top end first, that way if the hatchet slips it won’t hit the bottom end of the leg.
After hewing both ends, I set it up on the bench like this to shave each end in turn. There’s some fiddling around right where the angles diverge, but skewing the plane helps, and I got in there with a spokeshave too.
This is the finished planed leg. Once I do the other one, I’ll let them dry for a couple of weeks. At that point, I fine-tune the shape, matching one to the other more than to the template. As long as they’re close to the template, but closer to each other it will be fine. Then I cut the carving and joinery.
After lunch I worked on a carving for a box I’m making. A good day all around.
