Angle Attachments

AFAIK there is no attachment for this model. I have recently made a set of angles for a similar mountcutter from plexiglass. If you have no luck I can send you details.

Miracles take a little longer
I bought a generic angle-cutting template several years ago - probably from United. It is designed to butt up against the parallel mat guide, so it should work with any mat cutter that has one.

I'm not actually sure I've ever used it and, with a semi-functioning CMC, I'm not likely to. If I happen to run across it in one of my random searches, I'll let you know.
