I mentioned in Bill’s post on his knurled Star lock nuts that an integral stop could work too. Only bad thing is that it limits you to a set base to groove dimension.
I did some measuring to get a start point. With no die in the Star I pushed to ram to full stop. Measured space from bottom of ram to top of base where the die seats. I then measured the depth of the flange on my die and the distance from top of flange to the row of lube holes. I measured from bullet base to center of lube groove. A little math let’s me calculate the distance from the bullet base to the bottom of the ram at full extension.
In my case I needed a distance of 1.029 from bottom of punch to top of knurled ring.
Then it is just simple machine work.
Best part is that the base measurements are the same for all dies. Just measure die flange, top to row of holes, and bullet base to center of lube groove, a little math, and get to work.
All told this took 1.5 hours. In time I bet I could get it down to 30 minutes.
