I know I have said this before, but I will repeat again, use Mason feet under a lathe with caution, they move, they shrink, the lathe will most likely not stay level very long. I tried for 2 years to believe they would level my lathe, finally quit and made rigid leveling pads with bolts and indented iron discs. I truly believe Mason pads are made for leveling conveyors and outfeed tables, not precision machinery. I am sure someone out there is happy with them under their lathe but it sure as heck isn't me. I don't mean to come off as an arrogant expert but I have been setting up machinery for some time now and you could not give me a set of Mason feet to use for a lathe, mill, surface grinder, shaper. As an aside I know a guy now retired who set up precision lathes that he sold with nothing but bolts and indented steel pads, said all the synthetic padded mounts compressed over time. When you install half a dozen 10ee or HLVH and refuse to use Mason feet that says something to me. When I told him my tale he just nodded like he had been there long before.
