Corrected that squeak problem today! It turns out that the buckskin that I used in it to remove the squeak earlier actually was worn to a "shiny" finish. This made it squeak at the slightest movement of the pedal. To be certain there were no other areas, I checked this from the dampers on back, checking for noise as I added another piece of linkage. I replaced the worn buckskin with a heavy leather on the bottom and a thinner layer of leather on the sides of the metal push-rods. I changed all three of them so that I will not receive a call later with the same issue regarding the sostenuto and the una corda. Thank you to all for your great suggestions and words of wisdom.

I started a reply to you on this and lost it. I hope I'm not too late. When chasing a squeak, you want to eliminate as many moving parts as you can. For example: crawl under the piano with a flat blade screwdriver. Insert it between the dowel that passes through the key bed, and the lifter. Move the dowel up and down to check for noise. Noise.pull the action, lift the damper tray by hand.if no noise, reach under the piano and push up on the lifter. Noise would indicate the dowel needs lubrication. If the tray squeaks, you may have noisy damper lifters or dampers squeaking through the guide rail. If all is quiet from the lifter to the damper tray, operate the trapwork with the part that moves the lifter; then move onto the next part, all the way down to the pedals. Remember. Add one part at a time to the testing. Operate the trapwork a few times with the pedal to "warm" it up, then, move it slowly. If the noise comes back go through the above steps. CA glue is good stuff, but it migrates through porous material i.e. felt, cloth, leather, and sometimes wood. I use Aleen's Tacky Glue. It's sold in craft and hobby stores. I use the brown bottle.I think it's marked "Original Tacky Glue." It's very thick; does not migrate; sticks to dissimilar parts. I use tape to hold parts together until it sets. I found a lube that is silicone in a heavy base that looks like candle wax. Look for it in the hardware dept. I think its called Panpf or something like that. The package will tell you what kind of lubricant it is. It works wonders on noisy trapwork, springs, etc. Old parts of leather or felt, get hard with use and can glaze over from friction. If it's convenient, replace these badly worn items and add some lubricant. Lastly, don't let it intimidate you. You can refer to me as a helper that's been around pianos and their noises for over 30 years that sometimes can't find the fault right away. Be friendly and honest. Don't be afraid to say you're stumped for the moment. Sometimes getting away from the problem is a good way to find a solution. Let me know how it goes.

You may remember a few weeks ago when I asked for any help replacing the rubber grommets at the base of the pedals on a Horugel Grand. I was given some very good advice as to how to do this. The squeak (caused by the deteriorate rubber grommets) disappeared when I replaced them with buckskin. The pastors wife was happy with those results for a couple weeks and then the squeak returned. I spoke with her tonight and scheduled a service call for this Sat. 7-8-06 I am at a loss on this one. The squeak comes and goes. On more than one occasion when she called me to have this fixed, I arrived at the church only to find that there was no squeak. As I do not doubt a clients word (my goal is to satisfy all clients) I am extremely puzzled regarding this one. When I was there last, I went ahead and replaced some of the other "soon to wear out" pieces of buckskin in the trap workings. I glued them in place with CA glue. (buckskin to wood). Did I use the wrong glue perhaps? I certainly can't charge for this as the problem is not being resolved. I am looking incompetent! Can you help??? Any tips/suggestions welcome Thanks in advance Mark Mark D.
