Tim,
I don't think that is possible. ( I have had mine for about a year now) The fret board is held down by vacuum. Bridge plate is probably too small and orientated in the wrong direction. The jig radius's along it's length. And it is along the length that the radius vacuum holes are aligned. I suppose if there were more holes and the ones not needed while radiusing the bridge could be temporarily "plugged" then just one area of the plate could hold a bridge. It would need some serious thought/engineering. Good idea for a smaller version designed to do bridges!
Nelson, I talked to Craig about someday making something like that. I have been working on one that would. Craigs jig is made to hold down the fret board flat. A router then travels on radiused blocks along two oblong poles. so you can start and cut the radius from either a side to side motion or an end to end motion but the radius is in the side to side blocks and there is no way to mount a neck ( not yet anyway).
It is a great machine...one of those things that just works great every time.
I hope Craig doesn't mind me answering these questions...I am sure he will chime in and correct me if I'm wrong.
I'm glad you guys are loving it. I had the fortunate experience of delivering John's system in person as we are about two hours away from each other. Let me say, I definitely have shop envy...many cool tools and ideas were discussed. It can be dangerous to get two jig makers together. Even more dangerous if we had more TIME!
