The first time I cut locks, it would take me anywhere from 5 minutes to over an hour because of the same thing....cut, assemble, test, disassemble....repeat. And if I over-cut the lock, then I had to stretch the lockbar. So, I've made a few fixtures and changes to my process to make it quicker and easier and now it has become fairly consistent at around 5-10 minutes.
All of this is R&D right now and is necessary to me being able to continue offering this folder. I priced it much lower than the time it was actually taking me at first, hoping that I would be able to find these little "nuggets" of efficiency along the way. And so far, it is paying off.
