Delrin is quite easily available for the nut, but making the tickler looks problematic as I have no facilities for forging, heat treating or machining steel
So advice please! If I get some mild steel square bar will I be able to bend it cold without over stressing the metal, and will the face be hard enough without heat treatment if it has been work hardened by a good beating in the bending process? If I do work out a way to get the steel hot enough (BBQ and bellows?) can you harden mild steel sufficiently by quenching or do you have to case harden it, or maybe get some 01 carbon steel stock instead?
Finally I don't have a drill press - will I get away with drilling the nut socket with a hand held power drill or is this certain to lead to poor alignment and disaster?
Thanks for your help guys.
