Much has been written on the application of graphite to reduce
friction on wooden parts.  Most of the methods mention using alcohol.
Some people have good luck and others don't!

Those who use rubbing alcohol as a wetting agent are most likely
to succeed.  The reason this works is because rubbing alcohol is 30%
water.  In fact, it is the water that allows the graphite to bond and
build up a film.  Next time you need to apply graphite, apply only a
light coat of _water_ to dampen the clean wood surface, then apply
microfine graphite with a hard felt (piano hammer felt).  All doubters
should try this -- once!
