The FRPins were made oval for a purpose. On my wish list are oval center rail pins. If and only if that would help with with those dog leg keys where the bushings on the bass side endures all of the wear. In that case they would have to be extra oblong. Richard Hebendsthemforwardorbackwardandthencursesthosewhohave Moody. I actually thought about putting some duct, scuse me gaffers tape on the worn side. Until the client could afford new bushings of course... > I know this is treading on sacred toes, Good one so holy toenails? ?? ---------- > From: Newton Hunt <nhunt@jagat.com> > To: pianotech@ptg.org > Subject: Re: glueing controversy > Date: Thursday, September 18, 1997 7:57 AM > > > by twisting the front rail pin the bearing surface is decreased. > > I don't agree that turning front rail pins neccesarily increases wear, > but even so, turning is a temperary fix. > > Turning a little exposes as much of the pin as if it were not turned > because the pin is an oval and would have to be turned close to 30 > degrees before causing a problem, and when wear does occur by turning in > the opposite direction will give more use of the felt. > > I like new felt because it is softer and much quieter, but if the pins > were polished and lubricated and the felt were lubricated with a Teflon > based lubricant then far more use of the felt may be had. > > I know this is treading on sacred toes, but, like so many things, > intellegent use of resources and techniques can greatly extend > usefullness. > > Please note, I prefer to do my own key bushing because I aim for the > perfect fit (not always attained).
