---------------------- multipart/alternative attachment Hi Ed Good advice & strategy. Its hard to sell some pianist the "It'll break in with playing routine" however. The only thing I'd add to your prtocol is that the last thing to do would be to use a very dilute solution (^6-1) or whatever.on the top to satisfy these folks till it does breaks in. That being said you'll never sell a Stwy D that sounds like its only half baked to some one looking for a concert instrument. Dale Greetings, Inre my recommendation for using 5:1 thinned lacquer and being conservative, Dale and Bill have responded with the "other side". I sorta agree, but want to offer a little more of my own rationale. Dale said: Yes, but on the other hand if the hammers are really too soft the 5 to 1- will not get the hammer felt stiff enough & trying to switch to a thicker solution (3-1) solution later will only encounter the blocking effect of the first application & the 3-1 to 1 can't get in as far as it needs to go. I rather suggest experimenting on only a few hammers at a time in different registers to determine the appropriate remedy. I like to stick a single needle in various hammers as a probe to get a feel of the inherent stiffness or lack of it. If you call the mixture wrong on one at least you didn't whole sale treat em all & then say oops I shoulnda done that!. << By beginning my doping on the shoulders at 9:00 and 3:00, (a full eyedropper full on each one), I leave a "V-shaped" area under the string with very little lacquer in it. You can observe this with some colored lacquer on a scrap Steinway Hammer. The wicking effect takes the fluid in farthest in at the middle, forming a half-moon shape and usually reaching the core wood right at its tip. When this happens from both sides, the center of the hammer ends up drenched, with a graduated amount of hardener rising above it to the contact point, ( well soaked at the top of the underfelt and none at all on the surface where the string will be contacted). I like to let the hammers get played after this, and often, they will begin to develop a brilliance and range. If the player simply doesn't like the softness, or the hammers need more brilliance right off, then I add more lacquer from higher up on the shoulder, something like half an eyedropper at 10:30 and 1:30 positions. This seems to avoid the "blocking" of the earlier application, and usually begins to create much more dramatic results. It also leaves still a little untreated felt at the very surface and this is what I want. The factory method of soaking from the top down can make for a very nice sound, (once you needle the crashy sound out of a percentage of hammers thus treated). However, I find that the sound is not durable, and with moderate to heavy play, the sound becomes harsh. When needling the harshness out, I feel like I begin to lose tonal range. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
