Why is it that teflon actions are said to act the opposite of felt bushed actions with humidity changes, i.e. wood/felt swells with high humidity, thereby tightening around the center pin. With the teflon, the opposite is true.">> While it may, or may not, be true that Teflon bushings "act the opposite of felt bushed actions with humidity changes" the 'wood' acts like 'wood' does without regard to the teflons characteristics. Speaking of the Florida Teflon pianos that is where the problem lay, i.e. after several years, sometimes months, of swelling and shrinking cycles the wood could not match the outside diameter of the bushing and click click click went the teflon thingees in the flange. Taking a teflon action from living on the coast to the dry interior will cause clicking due to the same things that caused clicking in Florida..... wood expanding and contracting...... and the longer the teflon action lived on the coast the worse the clicking will be. I just happen to have a *few* sets of teflon thingees on my "take off but don't throw away because you never know" shelf, so I will try Jons water submersion experiment and let y'all know what happened.
