EMCO 5"

Hi to the list,

A little out, but does anyone know if the Compact 5 uses a standard
chuck? I have a Craftsman labeled EMCO Compact 5, and I'd like to know
the bolt circle diameter and
thread size of the bolts.

I measured the bolt circle at 1.142", and the bolts at .19 (look like
10-32, but they must be metric!)", but if it's spec'd, I'd like to here
the numbers.
