Crankshaft Repair

I had this crankshaft in my junk parts box for some time. Among its other problems, the threads on the flywheel end were damaged. I decided to see if I could repair them and possibly return it to usable condition. Since I don’t have the rest of the engine, I’ll have to assume that since all the critical measurements are good, the project was a success. The only reason for doing this was to see if I could. Also, it was a good learning experience.
