Well, this is why I'm hesitant to drill. It will not even be Good From Afar the way things are going so far. I did some testing on curved metal using a hand drill, and the bit was skating all over the place. I was sort of hoping that the tape would help with traction. The lines I sketched were quite rough, just wanted to get my hands on the job to see where problems might arise. I'll probably redo the lines more precisely, and see what I think then. I still love the speed hole idea, it is still in the plan, but it needs work.
