Slick Key Bushings.

[Isaac OLEG SIMANOT]

Richard,

While the trick of using CLP on problems bushings is very good, and having
some since the start may well protect the durability of them , in a school
environnement particularly, I am not persuaded we may have absolutely no or
very low friction in the key. I wonder if a little friction is not adding
tactile feedback and better control (assuming it is not too much)

Idem with graphite on the knuckle (yes there are yet people doing that) , we
loose some element used in the play when it is there (control).

Just my 0,1 Euro.
