Shaft Rolls OK Alone - But Wobbles When Assembled

I've got a cue shaft that has a bit of rollout in the middle when rolled alone. The tip doesn't move off the table, but you can see light in the middle as it glides over the table.

The problem is, when I assemble the cue, it rolls very badly, with the tip moving off the table.

The butt rolls fine alone and rolls straight with the other shaft as well, so I assume the butt is straight and the rollout in the shaft is the problem.

Any thoughts on this? The cue doesn't seem to play terrible, but knowing the warp is there definitely bothers me...

Shaft joint face

Sounds like the joint face on the shaft is not square. Try having the shaft joint refaced.
 
If you reface the shaft and butt and it still has the wobble the hole in the shaft could be untrue. I have came across some cues with the inert slightly cocked.
 
Have the shaft refaced.
Does the shaft screw on straight? how does it roll with the shaft backed off of the butt just a tiny bit? There's a slight chance the threads could be drilled and tapped crooked, and cause a wobble even if the face is true.

Take the cue to a good Cue repairman or a local cue maker and have the problem corrected. The reason I recommend this is because a qualified repairman or cue maker can fix the problem no matter what the cause is and they should check the cue completely. Below, is the break down of what the problem could be and what is necessary to correct it:

1. Place the cue in a lathe and check the cues pin for center and straightness. If more than 2 thousands out replace the pin, simple procedure.

2. Reface the shaft and butt, check for fit and check between centers. If the problem still exists go on to the next step.

3. Check the length of the pin and the depth of the shaft pilot. There must be at least 3 thousands more depth than pin length. If there is not a problem with the depth and all the steps have been checked or corrected, the insert or the bored and threaded hole is not straight. Remove old insert bore new hole install a dowel of wood or Phenolic. Then bore a new hole and either re-thread the hole or install a new insert. Easy fix!!!


The above problem can be corrected easily by a qualified person.
 
If the cue ever did roll true then check for a buildup of gunk on the joint faces.
It dont take much to throw the tip off like that.
If that is a new cue that you just bought it might be the reason the person sold it. Have a cue repair person take a look at it.

Face problems and check your pin first.
