I started out sandblasting glass and when I started with my first laser I tried doing the glass on the rotary attachment and it was mixed results as you can guess. I'm wanting to continue to offer my clients the glass engraving, but am wanting to streamline it a bit and not have to create the vinyl mask and then sandblasting. Does anyone have any suggestions on a rotary engraver that will do glass? It's just one thought I had and figured I would bring it to the experts to get your suggestions. Thanks a million.
