I have some shafts that were final turn about 2 months ago. My question is what amount of run out do most cumakers allow in a shaft before they scrap it? I have about 15 shafts and they range from .002-.015 in runout.
Shaft Run out
- Thread starter DD Custom Cues
- Start date
That's not much runout. Where are you measuring at?
Before using a shaft on a cue, I put it between centers & watch for wobble. A wee-bit of wobble is fine & actually can be expected. Anything noticeable that you feel would cause the cue to wobble when rolled should be scratched. A shaft has to have considerable warp or an off centered face to cause a noticeable wobble when rolled in the table. .002" is less than half the thickness of a human hair, with .015" being roughly 3 human hairs thick. That's nothing. 0.2" would be a warp you'd notice but even that isn't enough to cause the assembled cue to wobble on the table if it's faced correctly.

I measured about 12" from the tip end where the run out looked the worst. Thanks for the reply.
.002 to .003 you'll have a hard time noticing even between centers......
Anything over is discretionary............015 is too close to the line for a new shaft.
