Can you take a shaft down from 13mm to 12mm in one turning or is it better to do it over time. It is an old joss shaft so I'm pretty sure it is very stable.

By the time a shaft is cut down from a 1" dowel to a 13 mm size. It has been seasoned by cutting it in intervals, 6-12 times. Cutting it down by .040" is not going to matter. I have thousands of shafts that I have made smaller over the last 23 years, with no problem...JER
Thank you, thats what I thought too.
Thanks for the confirmation. When I was in Vegas in May, I had Guido turn 2 13mm shafts down for me. I was told by a person working at another booth that it was a serious no no. That they would quickly move. One shaft was turned down to 12mm and the other to 12.65. One had a slight taper roll right off the lathe and the other was perfect. They haven't moved yet.
I don't have as much experience or do work volume that many of the others on here do. That being said, most of the shafts that I've been asked to take down have a little roll or aren't quite straight enough to take down by machine. At least I'm not comfortable doing it when they are like this. I cut the ferrule down to size and then use sand paper. It takes a little time but always comes out nice. Less risky when the shaft isn't perfect.
A seasoned shaft has he stress equalized and cutting that shaft will disrupt the stress lines.
If I were to do that shaft I think I would make about four passes spread out a day or so apart ... or more ... all depending on how the cue spins the day after the first cut.
Some wood will take a heavy cut with hardly any movement.
Some will not.
There is no fixed answer for your question as the wood itself will dictate how long the process will take.
