I was actually surprised this worked but before I ordered a new gearbox for the crane on my LAH I did a temp. fix on the gear with stripped teeth. I disassembled gearbox, found the bad gear and it had a flatspot where teeth were missing. Using vice grips, I stretched the low area (soft brass) out close to where it used to be. I could still see where the valleys of the teeth used to be, giving me an indication of where they should be. Using a razor knife to start and then a hacksaw, I was able to make new teeth. It was not perfect but it worked, which it had not before, and lasted for about 4 weeks until I ordered and received the new gearbox(Marco Spec.).
