How hard is it to put a TRS lock parts set together? I have a drill press and all manner of taps, so if the holes are marked, that shouldn't be a problem. One thing that bothers me is hardening the frizzen, springs, and tumbler. Are there any instructions with the parts? I remember having to do this with the old Siler kits and the instructions had you tempering the springs in the kitchen oven.
