I have to drill a 4 hole bolt circle on a .5 diameter circle in a piece of brass. I maked my circle from center with a drafting compas. the bolt holes would be .375" apart. I mark it out but never get the .375" apart for all 4. What is the proper way of doing this. I figured I would mark it out center punch the marks and use my drill press to drill the holes.
I am only a hobbyist with a 6" lathe, milll etc. I do have a rotary table, but what is the best way to approach it to get it close to right. It is for a steam engine. Thanks in advance to all. Fred
