> I use drafting tape, 

Hi Kevin,

Gee, I forgot about drafting tape.  Many tape makers try to get the stickiest
stuff they can get or make.  Of of those glues are stronger than the substrate
they are applied to.  Drafting tape on the other hand is designed to hold the
paper in one place but the tape will come off without tearing the paper or
leaving some of itself behind.  Good stuff for weak or temporary stickum.

One of the problems with key pins is that they corrode.  Not much and not
visibly but corrode they do.  Using a real fine metal polish (Brasso is far too
crude) the metal can be polished THEN lubricated along with the felt and the
bushings will last much longer.  It is the polishing that helps the most and a
good coating of a good lubricant will help prevent future corrosion.

Any time you can rub the pin with the key bushing (apply sideways pressure) and
get drag it is a corrosion problem.  Don't believe your eyes, believe your
fingers.

Have a good week all.
