Seems like overkill unless you are building FC architectural models. (Do people still do that?)
I bought the bevel cutter from Attach-EZ at a WCAF show many years ago, and I think I've used it on one or two projects.
This may be one of those items that go into the "Useless Tools" thread.
Seems like a good idea, but how much use would a custom framer really get out of it?
Hand-made FC architectural models are very likely one of those skill sets that has been lost to technology.
So many better options for materials, and production methods these days.
That's not including 3D CAD modelling.
