Lucky for me, if all goes as it should the holes will all be hidden, none of them go through. And it's on the top, not the tank, so if I mess up completely . . . I'm going to try to get the special bit, unless I find it costs $45 or something like that.

Anita: Sounds like you have the basics down. There is a special bit that I believe has a different angle cut so it is less likely to 'grab' at the end. I have been lucky so far with standard bits though. Work on a flat surface like a piece of scrap wood. Place tape (painters works well) before you cut. Keeps the edges smoth and looks nice when you pull the tape off. Use a hole saw for large holes. Use a lubricant (water? kerocene) when cutting... -Paul _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com<mailto:GSAS-Member@thekrib.com> http://lists.thekrib.com/mailman/listinfo/gsas-member<http://lists.thekrib.com/mailman/listinfo/gsas-member> _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
