I got this Whitco screen door lock free from a locksmith, it had terrible tolerances so I originally used it to practice countermilling. It was sitting in front of me today and I thought, maybe I’ll just mess around with making some barrel spools. They turned out alright, I think I went a bit deep and the middle part of the barrel wasn’t wide enough but they grab the milling nicely! I have the easier FUN side with a mix of pins I was just messing around with. And the F#*K side has all barrels and torpedoes with matching countermilling, not fun.
