Thanks, Oxide. The customer was pretty happy with this one too.

I figured out the cause of my warm ground cable: loose screw holding the copper cable conductor to the clamp body. After tightening that up, I don't expect to be having warm ground clamp cables problems anymore.

Also, my stubby 3/32" gas lens collet body (CK worldwide) is toast. The copper piece that the collet presses against fatigue cracked, and broke completely away from the rest of the collet body. Maybe I tightened the collet one too many times, or took it through one too many heat cycle? Oh, the 3/32" stubby brass wedge collet deformed too. I guess I must have gotten it all pretty hot.
