    Hi Paul,

    The graphite grease is used quite a bit in tall case clock movements like Hershede etc. but can dry out over time and pile up like what William is describing.

    My feeling as to why the powder isn’t used for mainsprings would be that springs need a lubricant that will spread over the entire surface and stay put where powder might eventually end up at the bottom of the mainspring barrel. That’s just a guess though so could be wrong.
