Huge lathe chuck USED!!!! Came from a military auction 25 years ago. Weighs 300lbs. Still in working condition, except missing one jaw. Figure this would be useful to the average or experienced machinists. Adapter on it is for a huge machine, but can be removed to install on any machine with adapter. These chucks go for thousands of dollars. I make trips outside Richmond VA quite often and am willing to haul that way!!!
