<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Aggreeing with Terrys assesment of the RH range below, would also be interested in knowing if the Kawaii had plastic flanges or not. What was the general comparison between the Kawaii and the Steinway relating to centerpin friction problems you attribute to climate changes ?

Did you service the Kawai? Did it have action friction problems apparently associated with RH fluctuations? 30% to 80% RH range just doesn't seem too extreme to me. That is about what I observe in homes in the Tampa, Florida area. That is what my home RH commonly ranges. I have a Boston and have no friction problems at all - not too much, not too little.   <a href="https://www.moypiano.com/resources/#archives"></a> </blockquote> -- Richard Brekne RPT, N.P.T.F.
