I decided to be brave and attempt to cut out the glass for my next telescope. I've never done anything like this before and I'm having lots of trouble with it. I am using 3/4 inch plate glass and size 80 grit with a powerful drill. I attached a long 2 inch wide piece of sheet metal around the edge for cutting. I am keeping the drill at relatively slow speeds, approximately
30 rpms. I've been at it for about 2 hours now and I've only cut into the glass about a millimeter. I can't figure out what I'm doing wrong. Should I be using a different speed? Should I be putting more pressure on it?
