Built these based on a Charles Brock design. Walnut and Maple finished with OSMO. I got the 10/4 maple at the Hardwood Store and picked the 8/4 walnut out of the cut off bins. I hadn't done much sculpting before. Hogged the seat recesses with a Kutzall grinder. That is very hard to master so when I got close I switched to 40 grit for the concave middle and used rasps and files on the front. On the legs, after bandsawing I used a 3/4" round over about 6" from the top to fit the rabbets cut in the seat. From there I just used spokeshaves and hand sanding on the legs and stretcher. I had a Stanley 151 with a flat sole but needed a round sole for the concave edges. I bought a Kunz, figuring I could spend a couple hours tuning it up but never could get it to work well. So I borrowed a Lie Nielsen and it was the sweetest hand tool I've ever used. It also out shined the Stanley on the convex curves. I'm sure a lot of it was because of the much heavier blade. A huge difference in price but if I do more work like this I'll invest in it.
