Does anyone on the Forum know of a commercially available three jaw drill chuck that can be operated as a live center in the tailstock?
Frank,
The one from Pennstate was made like a live center with a drill chuck mounted on it. It would spin freely from the MT. I think it was intended to use a drill bit as a live center point after being drilled thus insuring everything running on center. It did not appear to be a double bearing or substantially built and I would be concerned about full time use as a live center.

I've never seen one. My Nova live center has a very short #2 morse taper for all the various bits. You could feasibly cut a #2morse taper down to fit. You can buy #2 morse taper to Jacobs taper adaptors and then fit a jacobs chuck or your choice on that.
Tell us why you want to do that and maybe we can come up with a better solution.
