I'm just getting around to restoring a Stanley #190 Hand plane which I inherited from my father-in-law. Wonderful man, Swedish cabinet maker. In doing some research, I've noticed it's missing a small piece, a depth setting device which is screwed into place, obviously to keep the blade at a consistent depth. I'm including two photos of my hand plane and one which I found which had the depth setting device. My question is: 1)probably impossible to come up with that part, but if not, how would I? 2) couldn't I just make something that I could screw into the hand plane that would be comparable to accomplish the same task? Thanks for any comments and suggestions.
