Wim,

That is bad looking, graphite on the sides of the whippen. I guess it was
not that black stuff that you sprayed, even protecting around.

Why not use McLube205 or such, or even nothing.

If you want really to use graphite, use some dag applied with hammer felt
scrap, or real graphite pencil from Renner's.

Did not knew that graphite in spray could exist.

Regards

Isaac Oleg

  Don't Mix

  Well, they do, but not with the result you want

  I am working on a S&S M, on which my predecessor had installed a new set
of h/s/f. He also proceeded to spray the tops of the wippens with graphite.
In the process, the hammer flanges got sprayed too. That resulted in many
centers being too tight, 2 or 3 swings.  Before repinning, I though I would
try a little Protec. The result was a very loose center, with about 12 -14
swings. Now I had to ream and repin. What a pain.

  Another good reason to use products judiciously. I have sprayed the tops
of new wippens with graphite, but only after taping off the flanges, and the
rest of the wippen. The only thing exposed is the top of the jack, and the
wippen on either side of the jack. This guy sprayed the top 2" of the
wippens. They were the original ones, too, not even new ones. I don't know
why he did this.

  Wim
