I have used lots of Master Oil on tool demos and almost everyone says that is the best lubricant they have ever seen. But I am like most others in not knowing where to get it anymore. Until Wayne's post I didn't know it was still being marketed. I won't be so chintzy with the few cans I have left anymore.
The one method I have seen used, and there is a portable machine that mechanical contractors use on Turbine overhauls, large machinery such as steel mills use, etc., called a "Disintegrator" It is basically a portable EDM machine that instead of machining a finished part from a base piece of material, is placed over the stud or bolt and VERY RAPIDLY just disintergrates the metal leaving a very thin piece that is easily then removed from the hole. I am sure unless you purchased one of these type machines it would be very expensive to hire the contractor for one small job. but perhaps check with EDM folks, either mfgrs., or end users and perhaps you might find someone doing small jobs on an individual basis, probably located around heavy manufacturing areas. Maybe this will help as an alternate source when all else fails.
