Schon question

Schon's have a 5/16 x 14 thread but some seem a little different then others. I have two and can't use the shaft from one on the other cue. Why is this? Has anyone else found this also? If they are different, and they certainly seem like they are, what is the real differance, thread pitch or what?

Send it to a cuemaker and he will start with a pitch gage, verify that the threads are in fact 5/16-14 Piloted, measure the outside diameter of the pin, look for burs or other foreign matter that prevents one shaft from fitting the other, measure the pilot diameters. It all boils down to this if it don't fit - it don't fit. You might need to run a tap through the threads to clean them up. You can try to force it and maybe screw something up (no pun intended) or don't do anything but give it back to the customer rather than dig into your pocket to replace two cues or shafts. If you don't know what to do - don't do anything that might damage the cues or shafts. At lease each cue is ok as is without any changes.
 
> Ever read on the Schon website where it says "screw threads do have idiosyncrasies,and we prefer a fairly snug fit"? That is because Evan is always experimenting,and he purposefully changes something every 2 years or so. I've seen his pins .007 over/undersized on the major (outside) diameter,.002 over on the minor diameter (bottom of thread),rolled threads,sharper threads,and several other tricks he uses basically to make it harder for other cuemakers to make shafts for his cues. This WILL cause a problem when working on them,so it is common practice to either buy or make at least 2 lathe pins for their shafts. My Schon was ordered in 1990,and delivered in 1991,it apparently has the undersized pin,but is slightly oversized on the minor diameter,and have bought 3 sets of shafts over the years that had to have a tap run into the insert before they would even begin to screw down. Hope this helps,Tommy D.

I own these cue and they are in fact different. One is an old cue and one newer, that may be the differance. Maybe a different manufacture of the screws? Strange.

not to hijack the thread.......but ok maybe a little. I shoot with a schon and ive been thinking of adding a predator or tiger x shaft.........how will i know it will fit.....or even will it? I figured all 5/16 by 14's were the same. Will i have to get a 314 or tiger x blank and send it to schon or a cuemaker along with my butt? man thats gonna be a pain...

That answers it.
 
MacGuy: Any chance you could post pictures of both cue joints side-by-side?

scottycoyote: I just purchased both a Predator 314 and Z-shaft for my Schon CX-61 - both fit like a glove. How old is your Schon?

My Schon is a mid to late 90's model. I have noticed it is a bit odd, as far as the pin is concerned.
My Schön pin = .306 major and .240 minor.
Atlas threaded rod = .303 major and .238 minor.
Threads per inch seem to be the same, but the profile is slightly different, as if it were cut with a 59° tool or something. My Schön shaft doesn't like going on off-brand butts, the butt will thread into standard 5/16-14 shafts though.

hey shar im not really sure how old it is..........neither of the shafts have schon stamped on them.....im guessing its a late 80s early 90s model.....
 
Some Schons and George cues used a .302 X 14, just like the old Mali quick release that used a .298 X 14. I have three taps for the 5/16 X 14 variations.
