graphite and Protec

[Isaac OLEG]

Sarah,

Graphite can turn bad with time very easily.

We need to lessen the friction on the roller (in some situations), but
you will certainly notice yourself if you make a few try, that you
loose much of your tactile feedback if :

Too much lube is used on the rollers
The hammers (and whippen) pinning is too free.
the hammers are too short and letoff happens too high.
The roller is shiny because of graphite transforming the surface.

That is for the last reason I avoid it there, all leathers are not the
same too.
The nap is supposed to be smooth, not glass looking, and that contact
is something directly felt under the fingers.

Micro fine Teflon is working as a charm, and does not make that
slippery feel .
I did not try the Jim's method, but I am cautious there.

Try it on a note , Teflon on another, you will see what you like.

Best Regards.
