Thanks for all the suggestions! I guess there's no easy way. I think I'll
cut the ebony guards to shape, scribe the scales, cut shy of the line, and
file/sand to fit, just like it's been done for centuries. If I were making
more than one, I definitly would mae a jig. I have a set of jigs for
making 1911 Colt auto pistol grips. Even a blind monkey could make a set
in under ten minutes.
