?David ? Thanks ? Those weights you posted by the way are for the heavier 16 lb Concert grand felt & are still quite reasonable.?For what it's worth I could have left them heavier but this was for my Swy B.? ? ? The weights of the newest?felt in 14 lb could easily match original hammer weights of Stwy,Baldwin,Mason & other high action ration pianos. ? Dale -----Original Message----- From: David C. Stanwood <stanwood at tiac.net> To: pianotech at ptg.org Sent: Tue, 17 Feb 2009 5:28 am Subject: Re: [pianotech] Wurzen/Weickert felt To All,? ? Another couple of final notes on this thread.... I asked Dale what kind of hammer weights he was seeing with these Weickert hammers and he sent me some sample data with hammers fully tapered, bored, and shaped. I made a graph of the data which may be seen at:? ? http://www.stanwoodpiano.com/RonsenWeickert2009-02-16.pdf? ? This set is 1/2 to 3/4 medium weight level except for the top octave which is into the low high zone.... Just wanted to reinforce the importance of Hammer Weight... it's a voicing component...!? ? My other comment.... when I was in School at North Bennet St. (1978) Bill Garlick taught us a technique which is very useful on these cold pressed hammers as a really safe way of using lacquer for building drive in the tone. Tip the stack up on its side and add some lacquer to the felt just above the tip of the moulding... do one side then turn it around and do the other... It gives foundation to the tone without having any deleterious effects on the surface of the felt and maintains a beautiful ppp quality that is the hallmark of a cold pressed hammer. The technique is consistent with the Dolge model of voicing.? ? Hope this helps,? ? David Stanwood? ?

"The art in hammer making has ever been to obtain a solid, firm foundation, graduating in softness and elasticity toward the top surface, which latter has to be silky and elastic in order to produce a mild, soft tone for pianissimo playing, but with sufficient resistance back of it to permit the hard blow of fortissimo playing."
