This is the drill I have, all I ever drilled for wc I drilled on this. The drill was 54 Euro, and the vice was 13.5 Euro. The vice is bolted for the drill table with two bolts. What I do is, clamp the copper tight into the vice, than unscrew a little bolts holding the vice to the drill table, so I can move entire vice forwards/backwards with some force. When drilling I just hold the vice steady while positioning the drill bit over the starting hole, than drill and position the bit over the next starting hole. This way I manage to drill one entire column of holes in the square pattern, then turn off the drill, unclamp the copper and position it for the next column. Similar to that I did when drilling the circular pattern.
It would be surely much better having the xy table and everything clamped tight (it would be more precise and less dangerous
) but this is the way I do it without (for now, hehe) xy table.
I hope I explained it good enough, if you didn't understand I'll try to explain it better.
