Yeah, MLCS has a good one and I would use one to get a little more length out of a shorter bit but not sure with a big old bit like that. It is a cool process, but I would have a hard time taking my good flat stock and hogging all that waste out. Seems like an awful waste of good hardwood
I quit making scroll saw boxes for that reason.. fun there is so much waste. I am more thrifty with my wood and stock budget!
