Got a new chuck | The Art & Science of Bullet Casting

I got mine off Ebay from a company called Ajax Industries in CA. The # on my charge slip is 402-935-. Cost me $399 shipped. I just checked Ebay again and there were lots of them available for less than $200 with a plain back or with a backplate to fit smaller spindle noses. The chuck with an integral D1-6 back cost a little more than a plain back chuck and then buying (or making) a backplate to fit but it is a little more compact and is ready to go as soon as you screw in the pins.

The cam lock pins on mine had a faint ring machined into the base about an 1/8" from the shoulder, I screwed them into the chuck until that ring was flush with the chuck back. I figured this would be close enough to figure out how much to adjust them in or out to fit properly but darned if they didn't fit perfectly and made for a perfect lockup.

My only complaint is the supplied T-handle wrench is a self-ejecting type with a spring that was so strong that it was just too frustrating to put up with. The scroll has a lot of mechanical leverage and has to be turned a lot to screw a collet in/out. About the third time the wrench shot out of my hands and into the chip tray I took it to the bench vise and did some disassembly work. Much better now! For what it's worth, the wrench is short enough that it can't it the bedways.

A note to purchasers of used lathes. I can tell if a lathe has been used in a trade/technical/HS votech program, it's the one with all the dings in the front bedway right up by the chuck.
