I just received my cue back from the maker after a refinish and had a new shaft made. I have had the cue back in my hands for literally 9 days.

Well went to play tonight and when I went to snug the shaft up... It went past snug... Not like i was cranking the crap out of it, just snugging it up.

Cue has g10 3/8 10 in it, and the threads just disintrigrated... What the hell happened?

Never had a shaft do this or even seen one do this. Been playing with 3/8 10 pins for over a decade!!!

Tried to call maker, but they are closed til tomorrow. My assumption is they will fix it, but I would like to know the possible causes
Just a bad shaft? Improper machining? I dont get it!!!

The shaft will still screw on, but only like 1/16" of the pin is actually holding to the shaft, and the feel is DEAD!!! Cant draw a ball 3"

From looking at the picture it looks like the hole was too big before he threaded it.
I could be wrong , so better talk to him.
He can replug that and thread the plug.

Im not all that concerned with the fix, as it should be rather easy... But he puts out LOTS of cues... I just dont get how this could happen?

If it was a new builder i could see using the wrong size bit, but not this guy...

Have seen this before, sometimes tap will foul with wood and when it comes out it tears all the treads out. Wood is probably soft also.

Could have also been from cross thread of G10 pin as G10 is real abrasive and will eat the threads up. If it lasted 9 days it is more than likely the problem as you would have noticed if
threads were missing when you received.

Stripped threads

This is exactly the reason I plug all my shafts with either katalox or ebony.

I plug all shafts with a phenolic insert and drill and thread it........... never strips out like wood...........

The black pin is the pin in the cue. I have a 3/8 SS pin laying around that I used to take a photo with the pin in the shaft. Its very hard to see, but look at the clearance of threads to wall... Its maybe on 3/32" of thread actually engaging on either side of the shaft.

Amazing. Three reasons for this.

1) because G10 should not be used as 3/8 material. Not enough contact area as with the larger 7/16 size but people are using what is available regardless of issues that can arise.

2) The threads pulled out because of poor machining when it was tapped.

3) The owner cross threaded and ripped out the threads himself (most probable)

The solution: previously stated - plug it. However, plugging changes the hit dramatically and defeats the purpose of using G10 in the first place. It really does change the hit!
 
My experience has been the G10 does change the hit to a crisper feel and the phenolic insert in the shaft adds to that. Together they give a cue a really nice hit.

Spoke with cuemaker, and they are fixing it, no questions asked, and covering shipping both ways. Gotta love customer service like that!

Still perplexed as to what caused it though... super weird

I know I didnt cross thread it... and the shaft was a week old, so its not like the G10 pin "wore the threads out"... maybe it was just a fluke thing

That's one thing to do it to a new build but I would not add a phenolic insert to another maker's cue unless the player specifically asked for it. It does change the way the cue plays and feels.

agreed............ I only do it to new shafts.......... I have done it to a stripped out shaft also.

how frequently do shafts strip out...?

I have never even heard of this happened, and have been playing for almost 11 years now. I have seen LOTS of broken shafts at the joint, but never stripped threads. Is it something that no one every talks about? LOL
 
This is exactly why manufacturers make gray, blue, brown and black suits to name but a few of the choices.

Hit is subjective and will vary among people. One thing for certain, that most everyone agree is that G10 is unique in its hit and feel. When you screw it into wood it gives you the hit I like and many others like. Once you add plastic, phenolic, pork fat or whatever type of insert other than what the shaft is made from, the hit changes to something entirely different. The insert creates a buffer.

In any event, my opinion is that the shaft was cross-threaded. One would have to assume the threads were intact and the cue maker released the shaft in working order. G10 will rip out threads like that especially on the 3/8 size by cross-threading. This is fact.
