10 inch Lathes**** Oldies but goodies*** need your opinions ASAP

I wonder what the spindle through hole diameter is on the Clausing. As Darren pointed out, the collet close for 4C collets is already sold and gone. The 4C collets have a .950" diameter up to the closing taper and a maximum capacity of 3/4" (19.05mm) stock. That doesn't mean the through hole was under 1", though it may be because the installer chose the 4C over the more common and useful 5C like I have.

EDIT: I hope this is wrong because I can't see how a 4C collet closer tube (which would have to be at least .950" diameter) could fit in an 11/16" (.6875") bore.
