I am curious about how much it would typically cost to change the threads of a shaft from like a uni-loc to a 5/16x14 thread or a 3/8x10 to 5/16x14?
Does the shaft have a brass bushing in it? If so then your shaft will prolly have to be inserted with a dowel, a piece of phenolic, or another brass bushing and retapped.
Also you should find Doug Patrick on here as I heard he is in your area and I think that he will do a good job for you. I would love to do it for you but I don't know how expensive of a cue you have as I am not as experienced as Doug and I know Doug is closer.
The uni-loc does have a brass insert and the 3/8x10 is wood threaded.
the quick-release can be retapped to 5/16 x 14 easily to where it will fit both 5/16x14 and quick release as long as you leave the pilot.going to 3/8x10 requires reinserting the shaft,if you would like me to do this ,pm me.
tomreed custom cues.

If you're going from a UniLoc to a 5/16-14, there's a good chance to remove the original insert, leaving the threads intact, and installing the new insert in it's place. Takes about 5 minutes. But, if the original insert doesn't come out clean, then it will need to be plugged and re-threaded before the new insert can be installed. Either way, it's a pretty easy job for any competent cue smith.
One thing to consider is the diameter of the joint size on both the new shaft and the butt. Depending on what the new shaft was originally made for it may not be the right diameter to fit your cue properly.
