Turning down a wobbly shaft

[rhncue]

For the guys who modify an existing taper by turning it, as opposed to sanding it, how do you pick up the centers of the cue? Do you lose the tip in the process?

When I held a shaft for cleaning using a mandrel on the joint end, and a concave live center on the tip end, it always had some wobble. I would have never attempted to turn it (instead of sanding it) to re-taper it.

Thanks.

If removing a 1/4 mm or less I just turn the ferrule and sand the shaft. If more than a 1/4 mm I have to remove the tip and put a new center at both ends of the shaft. If the tip still has a lot of life left it can be replaced as it will be larger than the ferrule after turning.
