Does anyone know of or recommend a brush DC motorized spindle about 3" OD 
and 6-8" long with a 1/2" drill chuck attached.  Common ones for multiple 
drill head drill presses are usually air driven.  But I am looking for 
one that is DC driven for a CNC drill press.  Is there anyone I can 
contact that would have a rebuilt or used unit?

Jerry,
As far as I know most portable electric drills use Universal Motors
which means they can also run off DC.  But that involves a high
voltage power supply.

Even easier are the whole range of battery drills.  The smaller
Makita's use 6 or 7.2 volts and fit your size criteria, come with 3/8"
chuck, thermal overload and could be run off of a battery charger.
Best of all, on sale they run under $50.00.

John.
