Well, RS, from your posts on stools and some other posts on chairs, I am getting interested in trying to make a Maloof-design, low back chair from Scott Morrison's plans. I thought it would be fun to see how much of it I could make on my CNC machine. While waiting on the plans, I thought I would try to make a stool to your design with the Maloof joinery. Well, my hat is off to Mr. Maloof, as well as to you. Getting those joints to fit as pretty as you show them is not easy.
I decided to make my prototype out of yellow pine - I had some left over from another project, and it is inexpensive. I made the top (14 inch diameter) earlier today with the proper pockets for the joinery, and I was felling pretty smug.
For the legs, I guessed that the head end of your legs was 2 inches wide, but I decided to go with 1-1/2 inches to match my stock. I machined a test leg (top only) to test the fit, and while I can make it work, the fit as viewed from the top is not perfect. I machined the legs from each side, and getting that radius that comes around to front face (top left on picture below) is not working well for me. For some reason, my design leaves a little ridge on the front.
But never fear, I am too stubborn to give up. Anyway, kudos to you for those pretty stools. And if you have any tips to share on achieving that fit, I would be happy to hear them.
