[Kelly McLaughlin]

Still cleaning house, no longer have a spindle this fits so it needs a new home Offers? trades? I need a set of small Vee Blocks also looking for Calfee reamers for 22lr if you have one sitting on the shelf : )

Was this originally meant to be mounted to an Atlas 12" commercial lathe spindle?

 

[Kelly McLaughlin]

It was an atlas accessory for sure they had several lathes with that spindle. mine was a 12 x 36 but not commercial, it also fit my standard modern 9 x 20.

I have one for my 10k South Bend as well. Handy for holding smaller parts before the collet chuck comes along.....

I've got one on my Atlas 10F. It was super handy before I got a drill press, but sees much less use now. I still use it every once in a while.

IIRC my Atlas MFC mill used a chuck like that. I also understood that the spindle for that mill was the same one used for their lathes of suitable size.
