My word ! I subscribe to MEW and occasionally visit the forum. Had a few moments tonight so thought I'd catch up on posts. Few moments !!-so many posts I'd need a few weeks. Does anyone make anything or are we all frustrated authors ?
Anyway having got as far as the lubrication posts I remembered reading recently that one should never oil a surface or tool and cutter grinder unless one was prepared to clean it after every use. The recommendation was to apply molydenum disulphide in some proprietary form and then wipe it off , the theory being that the microscopic molecular balls of moly would impregnate the steel/ iron surface at the atomic level and keep everything moving smoothly for a few weeks after which one repeated the treatment. The wiping off prevented any sort of adhesive or sticky layer from forming which would "fix" dust or swarf.
This seemed a reasonable theory to me . Any comments as to its truth from the atomic physicists or chemists ?
Apols. for risking starting a different thread on lubrication but having waded through 4 pages on the last lube thread plus another hour or two's catching up on other threads. Thought my query might get lost otherwise.
A final thought. I doubt we home machinists stress our machines enough to worry about what lubricant to use , given a bit of common sense , but grinders ,by their very nature are perhaps a bit more critical.

There are certainly several molecular bonding dry lubricants. Whether molybdenum disulphide is one I don't know. If I were to be in the market for some, I'd look in the US gun trade and buy from Cabelas or somesuch. They go in for that kind of thing so its easily found.
 
I keep my tool and cutter grinder dry. If it rusts I get that off with Plus Gas, which seems to dry to nothing and doesn't hold grit. (I think!)
 
Keep the felts pretty tight too, and soaked in Plus Gas, so that you don't get rust rings under the felts. Doesn't seem worn, or to be wearing, or not so I'm noticing, and as long as it sees me out, which at this rate it will........
