Repairing Shafts With Damaged Threads

Repairing Shafts With Damaged Threads FARM SHOP Repairs 28-1-36 Chris Gilbert, Waterford, Mich.: "I had a shaft with threads damaged so badly that I couldn't put a new nut back on. I tried using my trusty re-thread files with no luck. Then I thought about how I fix the problem when I cut a piece of threaded rod by putting the nut on first and then screwing it off after cutting to push the threads back into place. So I did just that. I cut a nut in half from point to point and then used a locking pliers to hold the nut together around the threaded part that's still good. Then I unscrewed over the damaged threads. I've used this idea on many different kinds of shafts and bolts."
