Some jaws interchange between Nova and Oneway chucks. Are the threads in
question the same? If so, can I know their specs whether I need to or
not?

Mangiamelli wrote a piece on that. Seems you only have to defeat the safety
feature on the Oneways.

But if you've got Novas, why bother? Nothing in the Oneway stable that you
can't do better on with Teknatool.
