I know that none of the mechanically astute individuals who make up this list have ever had an oil filter wrench "round off" the oil filter and make the filter essentually unremovable. When this happens on an M1 with limited access to the filter, you indeed have a problem.
After comtemplating the amount of work involved with pulling the engine, I throughly cleaned the filter and the inside surface of the wrench. I then mixed some JB weld which I applied liberally to the inside of the wrench. I put the wrench back on the filter and found something else to do for six hours or so.
It worked like a champ and the offending filter was quickly removed. If you wish, the wrench can be retrieved by the use of of a heat gun.
As always, YMMV
