Lathe "work truing" tool

[Canobi]

This is a well known tool but well worth posting for those yet to discover it and nicely presented.
I assume the other bearing is for bar stock, unlike face truing this needs some care as it works like a wobbler in reverse. In this use the bearing can not move so the work will if going slightly over centre try to climb over the bearing, nuff said.
Maybe useful also to mention re tightening the jaws after use.
I hope this is taken in the spirit of being helpful for the novice turner.

Absolutely, I am that novice turner lol, so thank you for mentioning the extra details I forgot to include.
