Scroll Chuck Centers

It was suggested by several of you in previous threads that it's a good thing to have on hand a stebbe center that's held by the chuck.

I also have the worm screw that fits in the chuck also.
Also in a previous thread, it was said that you need to remove the jaws from the chuck in order to clamp down properly on the center.
It seems mine is held tightly with the back edge (inside) of the jaws on my chuck (G#). Is it really necessary to remove the jaws?
Seems like it would loose its versatility not to mention being a PITA.

I think it depends on the chuck. The jaws on my chuck stick out further than the underlying jaws. On their screw drives this grabs the screw and also acts as a lip to keep the screw from coming out if it should get loose.
It looks like that drive center has a recess that might take the same lip of the jaws in my chuck but I don't know for sure. I certainly don't think it would hurt to leave the jaws on but can't say if they help.

Do you have a PSI chuck? Per your link it is for use with their c series #2 & #3 jaws.
Is your chuck a Nova G3 (the G# was a typo)?
If it is a Nova chuck the worm screw is mounted with the jaws on.
IF the PSI center fits tight I would not think it will be a problem using it with a Nova chuck with the jaws on. You will have to make that determination yourself as to how it fits.
I have PSI steb centers but mine are on a Morse taper. I really like them for spindle work with hard wood.

Yes I have the Nova G3 chuck. I'll probably try with the jaws on; that's what they're made for, right?

I also have the Stebbe center in a #2MT. I got it because I thought it was recommended to use one it the tail stock also.
Can you tell I really don't know what I'm doing?

Yours on the taper may be for use in the tailstock. Is it a live steb center? If it is you can't use it in the headstock (it will just sit there spinning and not drive the wood).
If it isn't it will only chew up the wood from the tailstock, or worse, really screw up your morse taper in the tailstock when it starts spinning.

I must have some blonde genes in me. Yes you're right it is a live center made for the tail stock. I just wasn't thinking when I was considering using it in the head stock.
Thanks
