When removing it, I had to stop and reheat. Twice. The thread was so long, and my pin wrench is so clumsy to use, that it took too long to remove it and it cooled off enough for some of the threadlocker to start working again
I kept thinking damn, this thing is going to twist off any second and its BRASS (soft) and I don't want it to hit the floor... but its also HOT and I can't grab it! I think when they made this one guy held it in one room and the guy doing the threading was in the next county.
What makes it problematic is that I wanted a piston on it that wobbles a bit... and with the threaded shank going nearly all the way to the bottom of the piston, it makes that more difficult because it means having to remove more material from deep in the piston... I wanted that material there for heat stability of the piston crown. I think I will end up having to cut the threaded part off a little bit so the shaft does not go as deep into the piston
