Can you tell more about the entire pin block epoxying proced= ure ? (I am interested by that). Regards, Stéphane Collin (Bruxelles, Belgium) </BLOCKQUOTE> I did this on a 110 year old Weber grand with a mortised pin block, and = it worked quite well. I shored up the bottom of the pin block, and pored a s= mall amount of impact resin in each hole and then drove in a 2/0 pin in each= hole. (in some cases, I was able to just push the pin in with my fingers, b= ecause the holes had gotten so big). I used impact resin back them because t= hat was what I was familiar with. There are now new epoxies that will do the= same thing. You want a slow curing mixture, because it takes time to put in= the pins. Impact resin gives you about 10 minutes to work with. So obviousl= y, I only did a small section at a time. In this case, the pin block also wa= s delaminated, so in addition to filling the cracks, the resin also filled t= he gaps between the lamination. To tighten the gaps, I clamped the block wit= h C claps in about four or five places. I let this sit for about 3 days. I removed the 2/0 pins, and then strung= the piano with 3/0 pins. Some of the resin will come out on top of the bloc= k. So when yo're all done, you can chisel off some of the excess, but it wil= l deface the top of the block. If you have an open face block, you probably = would want to put a nice piece of veneer on the top of the block. All you ne= ed to do is dimple the holes. A tuning pin will drive right through the vene= er. I did this about 12 years ago, and the piano is doing fine. There will b= e a little different feeling to the pins. They don't turn like they do in wo= od, but that is a problem only the tuner has to deal with. There is enough t= orque to hold the string. Hope this is enough information. If you need more, just ask. Wim </HTML>
