i have buggered up threads on the spindle and on the castle nut. I measured the spindle and the threaded portion where the castle nut goes is 1inch long. I took a picture of the spindle and enlarged it so I could count the number of threads. There are 16 threads within the one inch length of the spindle. I also put a caliper on the spindle and it is 3/4 inch thick.

I believe I need a 3/4 - 16 tap and die so that I can redo the threads on the spindle and the castle nut. Am I correct about this or do any of you know for certain that I am wrong in what I have done to determine how many threads per inch and thickness of the spindle?

Thank you

You cannot accurately re-cut the threads on the axle with a die-nut. if it starts in the wrong place you are going to bugger-up the rest of the thread. You need an old-fashioned clamp type thread cutter which fits over the inner section of the thread and winds off, which accurately re-cuts the thread. As for the nut, by a new one.

Geoff,

Thank you for the help. I believe victor Machinery in New York has a clamp style.

Regards

As it turns out Victor Machinery does not have the clamp style thread cutter that Geoff spoke of. Does anyone know where I can find one? Do any of you have one?

All help appreciated.

Also Murray Tools

Quick update on thread repairers.

Larry Garlock had given me the link to Murray Corp. for split die thread repairers. I contacted them via email and asked if they had the tool I needed to repair the threads on my rear spindle. The response I received was from Thread Tool Supply Company. Thread Tool Supply acquired the "Split Die" line of business from Murray in 2015.
They had exactly the item I needed, their service was excellent with friendly and knowledgeable staff. The split die spreads apart and can be placed on a good section of threads and can then be tightened onto the threads and then turned to repair the damaged section of threads. The link to their site is:

Regards,

Marvin
