Since 3 years, a lot of work have been done on almost all instruments, so many have been repined, new strings on some, actions refurbishing, new key bushings.</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>The problem lies on these last, all the key bushing jobs are showing a lot of side play, and even front to back play in some case. I was wandering how an other while relatively decent (but not too expensive !) repair job could turn in a so inefficient result. May be the bushing cloth used was very poor, but, as even the one which are less worn are noisy, I suspect that white glue or Titebond have been used for the gluing, causing the hardness of the felts and the fast worn out.</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>I consider using leather, for the schools now, I made a few sets on the balance mortise, and find the job to be not very different. Indeed the leather (Renner) is a bit more noisy, but I prefer that to have to sell bushing work every 4 years.</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>My question was about using leather in the front mortise, and if every kind of key pin will accept the leather bushing. For instance brass key pins may be will be worn out by the leather more than by the felt, so the play will be there , finally.</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>Is not leather in the front bushing really to hard and noisy under the fingers ?</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>I've heard that some of you use kangaroo leather , where is it sold ? any feedback ?</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>I was pleased with the 2 sizes of the Renner bushing, on the Bechstein and the Bšsendorfer I made I did not thin the leather it was very accurate ti begin with (and I did not use any oil on it, as someone wrote once, too afraid to have dirt and may be squeaks with this method).</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>Thanks in advance</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>Good Easter day to all, Pessah for some !</blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite>Isaac OLEG</blockquote> <blockquote type="cite" cite>  </blockquote> <blockquote type="cite" cite>Isaac OLEG Entretien et rŽparation de pianos.
