Sign me up, but I'll need a template. I noticed that you haven't spotted the holes or planned to cast "in" some of the possible holes, like the square hole in the cock.
Shoot. On previous iterations of the lock plate, I added a dimple for the tumbler hole. Must have forgotten when I created the new final master. I’ll make a template; may need some help with it, though.
I wasn’t sure about casting in the square hole. What’s your preference? Pros and cons?
