Flange Center Friction Increase

[Keith Roberts]

I would guess there is a coating of something on the pin that is gumming up
with the heat from the friction. Try heating a pin with a blow drier and see
if the pin gets sticky. Might be in the felt too.

> I am refurbishing a YC grand action. Hammer shank flange center friction
is all over the place, so I am repinning most centers. Some of the
low-friction centers have the following characteristics: First swing test -
9+ swings, then each time I test the swings, the number of swings drops by
one. So after the ninth (or there abouts) swing test, I'm only getting one
swing.
