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.
