New roll crimp tool
After much effort I came to the conclusion that Edgar was correct, the only way to get consistent correct roll crimps was a drill press. I have no space for a decent drill press in my gun room so I tried not one but two "mini" drill presses. Both turned out to be Chinese JUNK. Wobbly spindles, small lame chucks, and no torque. The hand drill will do it but consistency is nearly impossible (for me anyway). As I own a well equipped fab shop I set out to build myself a table top drill guide specifically for roll crimp shells. Beefy enough to last me a lifetime but small enough to stow when not in use. The results are pictured below. Total cost of parts was less than $100 and the investment of an otherwise wasted rainy day.
Problem solved, worked like a champ, easily adjustable for different hulls and gauges. (Edger was also correct about the 4 pin roll tool, much better than any I tried)
