I purchased this from a machine shop a little naive. Its not going to work for my application. Its a big boy. 12.5" Diameter 3" through Hole It is in very good condition. The mounting bolts have no wear on them and appear to be new. The jaws have no flattening or marks on them. To be honest it looks to be unused, or used very little. It has a little dirt and grime from sitting in a shop though. It is missing one of the mounting bolts. Let me know if you need anymore pictures or other info. Looking for $600, but willing to entertain offers. This thing weighs 90 pounds so shipping will be expensive. I will conver it on my dime. I'll accept Paypal, personal check, MO....whatever. I want to move this so I am listing it elsewhere too.
