I have a nice 6" Kalamazoo four jaw chuck for your consideration. This an older U.S made chuck that was used in a cylindrical grinder. The jaws appear to be reversable although the outside surfaces of the jaw show signs of grinder wheel touch. Pictures will clarify what I'm explaining. I believe this chuck is serviceable and has potential for a long life.
Asking $150 plus shipping.
I also have a Hardinge-Sjogren #2A Speed-Collet chuck with an assortment of 24 collets. It came off the same grinder and most of the collets show signs of wheel collision. I'm not sure about parting with this set since I'm still trying to figure out if I can make the speed collet chuck work on my 10L.
I would consider trading everthing for an Aloris AXA size quick change tool post and tool holder.
