Woodborg I don't have nova chucks, I do have Oneway chucks.

But don't the jaws have fitting ridges on the back of them, they would
not sit just on the screws, that would make for a very sloppy fit, so
no you do not place one set of jaws onto another, even if you have
screws that are long enough to do so.

As for the max RPM, lawyer safety IMO, I regularly spin them at 1000
RPM, would not expect a problem with that speed, just my opinion.

Have fun and take care

Hi
I finally recieved my cole jaws for the supernova 2 chuck. My question
to you all is; do you keep them on and then mount the normal jaws onto
the cole jaws or take em off after use.
I ask this as they have written on them, not to exceed 600rmp but tell
you to mount the normal jaws on them, but if you then spindle turn with
them on at 2000rmp...........
