Here's what I've been doing. I've been laying out the pattern on the fresh cap, marking it fist with a pencil mark, and then with a very sharp awl (not deep, just a mark I can see, perhaps 1/32" deep), and proceeding to drill with the standard drill bit from Apsco, by hand. I don't have much trouble keeping the angles right, but from time to time, I seem to have a bit of trouble with the bit 'wandering' off the mark. The people around me usually say "Wow, they're great." But they're not _perfect_, which is really what I'm shooting for. I've seen perfect, but with that drill bit wandering, it's a pretty tough thing to achieve. What can I do to keep the wandering bit to a minimum? Do I need a bradpoint bit? Do I need a pilot hole to guide the bit? Are there special bits that would do a much better job than the standard Apsco bit? Is there a technique that has eluded me? It's just a little thing, and for the most part, if I just went on making them like I do, people would likely still think they're great. But my own drive and desire to do the best work possible haunts me. (I want 'em _Perfect_!) Any advice? Best wishes to all, Brian Trout Quarryville, Pa. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
