Yeah, basically. The idea is simply that you're grinding this glass and not drilling it. You can't cut glass the way a drill bit cuts into wood. You're basically chipping away a bit at a time. The only reason for this is so when you finally plunge through the thickness of the glass (call it your pilot hole), you don't accidentally slightly twist the Dremel and break the glass... Picture drilling a pencil-sized hole in a piece of styrofoam and then snugly sticking a pencil in it. Now punch the pencil from the side. Crunch. Once you're in, you just want to grind away in as straight a line as possible.
I know I'm not describing this well... Obviously you're already well underway, but I wonder if any others would be interested in a mini seminar (scary word.. let's call it a demo) some Saturday afternoon at the Pet Gallery?
