Are you guys just letting the 1/4-20 thread stick bite the moving portion of the punch rod? Or is there some sort of a clamping block inside the mechanism? 

I’m considering totally geeking out and milling down some brass for the whole locking assembly/slide retainer. Dunno. I’ve got some trees that need trimming before I can get into the shop…and adding the brass takes this from a fun 1-hour diversion to a proper project.
