Ever had one of those times when you bought something and wondered if it was worth the cost? Would it really solve a problem?
I grew weary of dealing with drilling holes for Star sizer dies. Not on center, not all the same distance from the top of the die. No good way on drill press to index them so holes are 90° from each other.
I decided that as long as I was getting some other stuff from Shars I would get a 5C collet block set and a 3/4” 5C collet.
The critical diameter on a Star die is the two surfaces that seal above and below the area where the holes are drilled. Those are .750 so a 3/4” collet was perfect.
I can now grasp the die firmly by the lower .750 section. Rotate block to get 90° spacing. I used the front surface of the block to locate on the front edge of the vise to get same distance from top of die.
This is far and away the easiest, fastest, and most accurate system for drilling those holes I have found yet.
