I am wondering what is the proper way to drill holes for ejector pins. Textbook calls for +.002" to depth of 3x diameter and then + 1/32" all the way.
I am using 3/16" ejector pins. Do I drill a smaller diameter hole, then ream, flip the mold over and then drill to +1/32" oversize?
It's a class project and just drilling with a 3/16 drill seems to work, but I am wondering what is the proper way to do it?
