Can someone give me information on drilling glass.

Delphinus,

I have used a Dremel (well, at least the Sear's version of Dremel), to cut glass and ceramic tiles. I haven't used in aquarium applications, but I have used it in my hobbies. There are a couple guys on RC that have done it before.

I don't think the bulkhead needs an 100% round hole for it to work. Since the dremel removes material at a snail's pace, you can slowly shave the hole to the desired shape. With a marker, you can trace the outline of the bulkhead (inner part) and use the dremel to slowly shave the material inside the marked area. The outline should be round enough for it to work.
