Got these off our local Face Book buy sell trade site for 20 bucks. Been looking for the Jacobs armature chucks for years and didn't want to pay ebay prices...Bob

I'd say that deserves a

Good find Bob.

They can be handy, I have had one for many years. I was in millwright school and the instructor came to me one day with a box full of starter armatures and asked me to turn them. Said "sorry can't, I havn't been checked off on the lathes yet" To which he replied "shut up and go turn them, I know you have a lathe at home and do this all the time" So I said OK, but I will do them tomorrow. The next day, I showed up for class with my Jacobs armature chuck, and proceeded to turn and undercut all the armatures.

They are very handy for those armatures that are not centre drilled and since the bearing journals are often hardened, they can not be centre drilled easily.

Mine does not get used as much anymore since I got a Bison 3 Jaw self Centring Rotating Chuck. See http://www.kbctools.com Page 517 for a picture.

Bob,
All for $20 ............. you definitely deserve one of these

Yup, definitely deserving of one of these.

Nice find Bob.

I just rebuilt the motor in my shop vac and got lucky because the shaft was center drilled. I have used the armature chucks in the past though and they are very handy. That one looks brand new!

Oh, by the way...
