re: Going in Circles

I'm thinking I might raid my wife's collection of glass cutting tools for some tests. I've never tried anything rotary on veneers and her tools, gantry cutter (like a panel saw), circle cutters, etc. all have the small wheel, but sharp.
The circle cutter is nicely rigid and precise, tailored for smaller circles (<6"). The straight cutter is one I "improved" by mounting the cutter head on a linear bearing.
