That’s going to work very nicely for you Peter. I made one a few years ago that employs a razor blade clamped between a couple of little blocks. If you contour the blocks you can get a curved cut. It’s a very cool little tool but I haven’t used it much at all. ……. Too many projects, too little time.
But you have employment for this fine little unit so it won’t be languishing on the back of the bench like mine.

Nice one.
