Another lathe "work truing" tool

[Christophe Mineau]

Hi Logrod,
This is funny, this is something I tried last week end on the wood lathe.
Actually I had medium result, and I concluded that the main thing that didn't make it work was the difference between my wood-lathe chuck and my metal-lathe chuck.
The metal lathe has smooth jaws, allowing for some gliding adjustment if you don't tighten it too much, where the woodworking jaws have a grip and do not allow for that.
Of course, if you can find some smooth jaws for the woodworking chuck, it would allow the adjustment, but on the other hand, you will loose in safety.
I think I will keep my grip on the jaws

It could be interesting, for the bowl alignment you are talking about, to make a kind of truing plate that would fit in the tailstock, with a disk large enough for touching the edges of the bowl, and that would be true to the lathe axis.
You could apply the bowl against the disk before tightening the chuck.
Could work, maybe not ...
