Its more about his tool control methods and tool edge angle of attack. I dont use his convex bevel, but I do use a narrow bevel, ~1/16”, with a secondary bevel and heel ground away, kind of simulates his grind ( I use a jig to sharpen).
Did he say to use a 1/2" bowl gouge? If so, it's a pretty shallow bowl gouge he's got in his hand. Thanks for sharing, Reed.
it would depend on the width of the gouge and the depth of the flute and the thickness of the forged bar.
I would say no (but what do I know, I've been doing it wrong). You need a fingernail grind, with a little side bevel, to do the cut, and a stiff tool is very helpful. The continental gouge could be ground with an atypical, rounded end, but I would not expect them to be rigid enough.
In the video clip I use a 3/8 spindle gouge to back hollow. Also drill and give brief review of the ABC basics.
A gouge is much like a spoon bit. Saw a show where Roy did a bodger style chair.
The way I learned the use of a spoon bit was talking to Don Weber at the 1992 symposium at Provo Utah and subsequent research into the art of chair making. The photo of Don Weber was in the Sep 1992 American Woodturner - black and white and SEP/OCT 1992 Woodturning (UK).
The basic technique is to first make the horizontal rungs with straight tenon ends, allow them to dry then finish to size. The next step is to make the verticals or legs from green wood and using the spoon bit make the holes such that the inside is larger then the entrance hole. The assembly is then done while the legs are still very green. The rungs are assembled with the annual rings vertical so that as the legs dry they will shrink around the rungs.
The chair shown is the first and only one that I ever made during a family vacation in summer 1995 on Crane Lake. The pieces for the chair were all made of black ash from the same tree that the shave horse was made from. The only power tool used was a chain saw to cut the tree down and do some of the shaping on the shave horse. The chair parts and legs on the horse were split using a froe the shaped using the horse, draw knife, spoke shaves and brace & bits.
