Hello. Ive foolishly started fixing my fathers chummy and the problem is that the starter dog nut won’t go into the threads on the end of the crank. The reason this has happened is because the threads removed themselves from the nut and have welded themselves into the end of the crank. I have since found the correct taps but they don’t seem to be taking to the cranks. Is this because I have a phoenix crank that has been hardened? Do I need HSS taps? Is the hole now to small? Oo forgot to mention, it’s a mag engine. Any help would be appreciated. Cheers.
