I may have the opportunity to cut out a bunch of wooden "donut" shapes. Approx. 15" in diameter with a 2" cross section diameter. It would need to be a two-sided cut, which I think I can figure out. Probably four profile cuts with a round over bit. Two per side.

What I'm not sure of is hold down when the piece is flipped over. Using a round over bit I can't leave tabs. Any suggestions would be appreciated.
