Can the pin / joint size on a shaft be changed from a 5/16 X 18 to a 5/16 X 14 ?

Yes , I would recommend plugging and re threading the shaft. Then replace the pin in the handle.

Yes I do stuff like that for customers, all the time.
It takes a little time, since you have to drill out the old insert and plug the shaft before installing the new insert

If both inserts have the same major thread, can you just heat up and remove the old insert, then epoxy in the new one? Just curious.

I don't see why not. I just feel it is so much easier to just bore out the old insert and start off fresh. Heating the old insert for removal you always run this risk of charring the shaft, ruining the threads and deco-rings. The correct way, I of coarse am assuming that boring and plugging is the correct way, leaves the finish product as good as new.

Thanks Dick, so what thread on the plug would be used? like a 9/16" diameter thread?

You'd be really coming close to that 5/8 tenon if it's threaded.

Thanks Joey, that makes a ton of sense. LOL. I was just trying to stay away from the 7/16 thread of the brass insert.

Thanks to all for the feedback.
I will definitely not try this myself - but a top cue tech should be able to convert
from the feedback I read.

It is impossible to re-thread a cue shaft insert using a tap and die set.

Cool,
What else do you know?

The president and chief engineer for Cutting Tools provided the information I posted. They specialize in this type of work.

I'll bet he didn't know this thread is 9 years old.
