This 3-legged chair is designed by Scott Morrison. The plans are on his website.
I recommend this chair as a 'starter' project for anyone intimidated by Maloof style rockers. It's a great intro to the joinery and sculpting, but it's less complicated.
I'm making a pair. One will be walnut, the other curly maple. The pieces are all laminated from 4/4 stock, although the plans call for 8/4. It has made selecting grain pretty tricky.
I'm in the middle of shaping the legs. I bandsawed them to rough shape, then used a block plane to smooth the flat and convex sides. For the concave side, I used a rasp to get a smooth sfc. Next, I switched to my $10 spokeshave and Lee Valley contour plane. They are magical. I scribed a line down the center of each side, and rounded over to the line. Each leg takes about 20 minutes. No dust.
