I will be drilling some plates with holes around 13/16 that have to match up. The bolt hole pattern is for eight holes on three different plates that have to match. From what I understand there will be 26 sets of three. One set if the three will be done by a machine shop and the rest are my responsibility. I am thinking of an accurate scribed layout, pilot drilling and drilling one plate to use as a master before stack drilling. The plates are around
3/4 thick. Any suggestions on how to make locations more accurate??? I am limited to a radial arm drill press. No milling machine. Edge distance are not critical but hole pattern is. Randy- posted
