Hello, I am in the search for a used Kellenberger 1000U ID/OD grinding machine. Ive located one in York Pa. and am likely going down there at some point to check it out. It is under power so I can see it run. My question is , what should I be most concerned with in inspecting a used machine? What can I look at to give me the best determination as to the machines value and reliability. It is a 1981 model, and appears well used. are there any telltale signs to look for abuse? I dont have a lot of experience w ID/OD machines, so Ill appreciate any advice you may have. Thanks
John
