Nods.. was going to, but I didn't. So my own self induced fault. I am currently designing something table top to use those 3-4 items based on some old drills. Might as well put that draftsmanknowledge to use, right? Even then the constant changing of brass will eat up some time, but HAS to be better than manually turning everything.
Anyone know if the metal on the modified shell holders are weld-able? Thinking a small vertical rod welded to it would speed up loosing and tightening quite a bit and allow big fingers to get in since the frame may be a tad close for stablity's sake.
