Be aware though that measuring Dw and Uw on teflon flanges is a bit different than on wool bushings in that with teflon flanges there is more initial friction resistance to movement, but once the part is in motion, there is very little friction resistance. May be part of the reason for its wretchedness in play - harder to control the action.

I'm looking at trying to remedy a Teflon action in a 1974 Steinway "L" , in a fancy hotel lobby. It feels clunky, heavy and uneven. ( Not much fun to play! ) I'm planning to offer the management a variety of options for improving it, from just lubricating all the non-Teflon friction points ( and the Teflon ones? ) to trying to regulate it, to replacing and regulating the whole shaboo. ( $9,000 ??? ) Can these things be regulated, according to traditional protocols, with any hope of success ? How would you experienced fellows approach this ? I've replaced one before, but the managemant might find the cost prohibitive. It doesn't seem to be clicking. Its' just wretched to play on. Any and all suggestions will be most gratefully receieved! Thanks! Thump ____________________________________________________________________________ ________ Want to start your own business? Learn how on Yahoo!
