Hi,
I was going to comment on that.
You said you were going to get spray teflon or something like that.
I tried to post a picture of the original instructions from the booklet I found. I can see them fine, but maybe they are too small for others?
They mention using Parafine or candle wax or something similar. Parafine is an oil based wax. I am going to look into something like Bee's Wax. Basically I'm looking for something that is not sticky and will not dry into a tarry mess. As I see it, if Snap-On circa 1949 put wax on the sliders and they still seem to be in good shape today, why change?
However if you find that the teflon stuff is good and not accumulating dirt, etc. then I'm interested in hearing what your results and feeling are about it. I've never used it and have no idea. Maybe test it on something, like a piece of paper or bolt threads and see if dust sticks to it?
Since we have the whole thing apart and can put lubricant anywhere we want, I was toying with the idea of graphite powder for the same, slippery but not sticky, reasons.
