I know, I know... this is a broken record but I've used predominatly Lower density hammers on most asian pianos with enormous success. If this was a Yamaha 9 ft I would suggest Renners with Weickert special felt when they come out.This belly & string scale requires denser hammers in my experience. The smaller pianos like this are a fine candidate for the Wurzen AA or Weickert special. Dale I was approached by a local school district about regualating their Yamaha C5 which is in a classroom and used a minimum of 5 hours daily. The piano was new in 1978 and the hammers appear to have never been shaped. For a number of years it was kept on the stage in a closet reserved for it and used minimally. about 9 or 10 years ago it was moved to the classroom and has remained there ever since. The hammers could be shaped but with the use they get would not last more than a few years and they are marginal for shaping anyway. I checked with Yamaha, I recalled that they used to offer a fairly low price on hammers mounted on shanks with flanges, the current price is $1400 and change. This is a public school and price is a concern however doing the job correctly is of a deeper concern for me. My concern is, putting new japanese hammers on a piano of this age, since it isn't being restrung. For a few hundred more I could replace the shanks/flanges and replace the hammers with after market like Abels or Ronsens. I fully intend to rebush keys as necessary, bolster backchecks do any other necessary repairs and regulate after the hammer replacement. My reason for posting is, I'm looking for feedback and suggestions from those who are experienced with hammer replacement on asian pianos of or nearing this age, agree or disagree. Mike -- I intend to live forever. So far, so good. Steven Wright Michael Magness Magness Piano Service 608-786-4404 www.IFixPianos.com email mike at ifixpianos.com Worried about job security?
