I wouldn't think that those 75 year old hammers would need much juicing at this point - chances are that they're already well beyond "firm". Try removing and twisting the bass strings, or if you can afford the time massage them thoroughly before reinstalling with a twist. You'll often be surprised at how much you can bring those old strings back to life. - Mark -----Original Message----- From: Tom Driscoll [mailto:tomtuner@comcast.net] Sent: Monday, September 29, 2003 2:36 PM To: 'Pianotech' Subject: RE: Voicing an old piano Hello List, I have a client that has an old Raymond upright. It's about 75 years old but it still plays reasonably well. I wanted to get some advice on voicing the hammers in this piano. I've already filed all the grooves out of the hammers, shaped them and shined them up all purdy like with hi-grit sandpaper. This helped the tone quite a bit but there is still a long way to go. This is where I need your advice. The bass sounds quite tubby and as you move up into the tenor and high treble, the sound just gets brighter and harsher. The owner actually likes the brash sound in the treble so I wanted to bring up the bass a bit so it doesn't sound so muddy and matches up somewhat better to the tenor area. So, what should I do here? I'm thinking because the strings are 75 years old, a large part of the problem is there. Restringing is not an option here but do you think I can juice up the hammers enough to make a difference? I have a solution of acetone/keytop and was just thinking of using a few drops on the crown of the bass hammers. I know that this probably wouldn't be the way to treat new hammers but what about old worn out hammers. I'm thinking this may be all I need to bring 'em up a bit. Any comments would be welcome. Thanks, Corte Swearingen Chicago Corte, Before juicing up the hammers try twisting the bass strings. Start with the worst offender to experiment. 75 year old bass strings are almost always tubby and twisting can be an improvement. Be aware that the tuning pins will be less tight after doing this and string breakage @ the tuning pin can occur. Correct regulation, stable action centers and A440 pitch contribute to improved tone also, but I'll bet those strings are the issue. Good luck, Tom Driscoll RPT
