I bought this off of eBay, then realized it is 5/8", instead of the 1/2" version I wanted. Someone give this a good home.
Jacobs chuck, used but in very good shape. It turns easily by hand but is not at all loose. I chucked up a 1/2" gauge pin, put a travel gauge on it, and spun it by hand. 0.001" total runout. Crazy, just dead nuts.
I'm including the MT2 JT3 arbor I bought from Amazon.

I didn't check to see but I believe that is the ball-bearing super chuck...and it is aptly named IMO....One of the best they make!!!!

JT3 not a JT33 correct? I need a new chuck for my drillpress but it's a 33. I'll take it if it's a 33.
Never mind, just looked a little closer at your last pic. Oh well.
"73 is the best number because it's the 21st prime number, and it's mirror 37 is the 12th prime number, whose mirror 21 is the product of 7 times 3. Also in binary 73 is 1001001, which is a palindrome." - Dr. Sheldon Cooper
