    I use Lucas Red-And-Tacky grease on Model 14/15 motor
pinions.  Those turn fast enough to throw off grease
by centrifugal force.  That's the problem with open
gearing. Nothing else in a Teletype turns fast
enough to need it.  For everything else that
needs grease, I use white lithium grease.

    The main issue with oil is using something that
evaporates cleanly without leaving heavy fractions
in the tar and asphalt range behind.  WD-40 is awful.
I use 0-20W synthetic motor oil, which is cheap
and all one molecular weight.  It seems to be
necessary to fill the oil fillers about once
a year to keep up with evaporation.

    Spraying is too messy. Get one of those
pen-like things that deposits one drop of oil
with each push.

    Misery is repairing a machine gummed up with
bad lubricants.  Everything close-fitting has to
come apart for cleaning.  I've done this once.
Not fun.
