Screw or bolt, switched partners!

[Flatfoot]

I don't know whether the fastener which joins shaft to forearm is called a screw or a bolt, but I will explain my problem.

The screw which has always been fixed into the forearm on my jump-cue, switched to being fixed into the shaft, last night when I broke them down after playing.

Any suggestions? Should I find a way to get the screw out of the shaft, without damaging it, and then put a dab of glue on it...and screw it back into the forearm?

I believe it wouldn't make any difference in the performance of the cue, since I would still be able to get it tight when putting them together.

But, alas...I am ignorant of what I should do. Any help is appreciated.

I short, the answer would be yes. The joint pin needs to be removed from the shaft and put back into the forearm. It will actually make a difference unless you have a joint that I've never seen before. The shaft has a brass pilot in it...the forarm typically does NOT. Eventually that wood will wear down and that tight fit won't be tight anymore.

Depending on what's actually happened it might be very easy or somewhat of a pain in the ass to get it out. Now as far as putting back into the forearm, that's not truthfully as simple as a dab of glue so you might want to find a local repair person who can do it correctly. Just screwing the pin back into the forearm with glue is not going to make sure that it's running true and you could end up with some rollout. Do you know what actually occurred to cause this? Over tightening will do it but poor construction could also be a cause.

so how do you know it has a brass insert,because I didn't see that in the post or the make of jump cue. Ask questions before giving suggestions

Yeah that's a bizarre statement without seeing the cue.

Sounds like it was over-tightened and the joint pin came unscrewed from the forearm when unfastening the cue and there was no glue or glue breakdown for it to stay put and unthread from the shaft. If the shaft does have an insert that's the same metal as the pin, they can get stuck together and that would be a bigger problem. Otherwise I'd think you could grab the joint pin with pliers to carefully unscrew it from the shaft and reinstall it into the forearm with some glue as long as the threads aren't damaged, right?

<-- word of caution, I'm an amateur at this; don't act on my suggestion without a builder or repairman saying so

A safe way to removed the threaded pin from the shaft is to install 2 nuts that properly fit on the threaded pin. Screw them on the pin so that they 'lock up' together and leave a space between the shaft and the first nut. Then with using a wrench turn the first nut counter clockwise. This will keep the 2 nuts 'locked' together allowing the wrench to unscrew the pin from the shaft.
To put the pin back into the forearm, you can use the same method but put the wrench on the outer nut and turn to clockwise. Make sure both nuts are 'locked' together. Some glue or epoxy will be necessary to keep the pin in place. Keep turning the pin until it is at the same/proper length.

That's valid I suppose and I should have asked if the shaft had an insert. That being said, I've seen one brand that didn't and that was McDermott in the early-ish 90s. They used a 3/8-10 for their jump breaks for at least a period time and may very will still.

The assumption (yes it was an assumption,) was that with it being a jump cue, it would follow what has become standard construction. Meaning that it would have a very light pin (usually a 5/16 of some variety,) in which case it should have an insert.

Since the OP hasn't posted anything in reply I simply can't be sure if my assumption is correct or not. /shrug
