So I optimistically bid on a Kuhlmann SU-2 cutter grinder on ebay. Not many pictures, but considering the price was relatively low I thought what the heck. I won the auction, and it finally arrived.
Upon close examination, it became obvious that the entire grider had spent some time underwater. The silt inside the electrical box under the motor clinched it. The spindle bearings are toast, as are the motor bearings. From the appearance of the oxidation inside the motor housing I suspect it may have been salt water. The rest of the machine is in fairly nice shape. Everything cleaned up to usable condition. The motor runs, however the bearings make the noise of bearings past their prime. Now the question is, do I just replace the motor bearings or is this a catastophe waiting to happen. There is a small amount of rust on the stator magnets, although apparently the windings are still intact. It will be impossible to thoroughly clean the rust from the stator and the oxidation from the inside of the housing without further damage. I haven't priced a new motor yet, but expect it to cost big bucks. If anyone has any experience using electric motors after a bath, I sure would appreciate hearing some opinions.
