    All the ones that I have seen have the felt folded over the fiberboard. You can get fiberboard sheets from NY Steinway. I have never found it available locally. The old ones seem to have the felt attached to them by shellac. Newer ones use glues...

    There is nothing wrong with puling the pin or 2 pins, as long as they come out easy, and go back in easy. But here in Hawaii, most of the time the hinge pins are corroded, and it (they) are very hard to pull out. ------------------------------ Willem...

    If the pin will pull out, I lubricate it with a little VJ lube when I put it back in. I also leave it a fraction of an inch out. Sometimes I've found it inserted from the back. I always move it to the front so it can be pulled forward to remove it....

    Definitely the folding under is not OEM because it is so hard to get it right. However the color of the fiberboard does look to be OEM to me. Pwg ------------------------------ Peter Grey Stratham NH 603-686-2395 pianodoctor57@gmail.com ------------------------------

    You could repair that. Remove keytop, cut the key square along the break, glue on an appropriate size piece of wood, dress to size as needed, install new keytop. Not that hard a job, and I would think a lot less trouble and expense than getting a new...

    Is it possible to buy one key or have it made? Someone vandalized a practice room piano. They split off a big chunk of the key and took it. You can see the impact cracks in the key, so it looks like it got hit pretty hard.

    Sometimes there are two hinges. Yes you can remove the hinge pins and then remove the lid. Or you can take a 3 ft dowel of .5 diameter, drill a hole on one end in which you put a balance key pin and on the other end you can glue a large rubber button....

    That does not look OEM. All the one's that I've taken apart have had the cloth glued to the top and cut flush to the bottom. Brass half-round is fairly easy to bend to the curvature of the plate. ------------------------------ Regards, Jon Page ------------------------------
