Do you think the comments below were dismissive? I don't and it they certainly weren't intended that way. I don't know Mr. Finley or whether he is an experience tech or a pianist just wondering about the mechanics of the instrument but gleaned some level of experience from the way the question was asked. Walking someone through a step by step procedure as they try each potential solution is a bit beyond the scope of what can reasonably be accomplished here especially, as you see, when even the experienced techs are throwing out solutions that may or may not address the problem. That was my point. But all questions are encouraged even if the answer is to go find a more experienced tech to help solve the problem, something, btw, that we've all done at one time or another. Let me also say that I always encourage pianists to increase their knowledge about their instrument. Honestly, I'm often shocked at how little pianists know about the instrument that they often spend countless hours at each day. That being said the PTG website lists pianotech as a discussion list among hundreds of piano technicians. It is reasonable to assume then that those participation expect that the questions are coming from other technicians. If you are not a technician and want to pose a question that's fine with me but it's probably best to say that otherwise a certain level of knowledge may be assumed and you may not get the response you were hoping for. Personally, I might be inclined to answer a question coming from a layperson in a different way than coming from a technician and I am often in that situation when giving presentations to, say, piano clubs attended by pianists, not piano technicians. That's not an issue of condescension but in couching the answer in familiar and perhaps non-technical language. It is helpful if the person answering the question knows their audience. The same goes for the person asking it.

Assumptions are a funny thing... I am not a tech but read this site every day (several times a day). It is interesting that from time to time some "techs" can get fairly dismissive towards those that ask questions. It is impressive to me that quite a few piano players seek to find out what makes their particular piano tick and are willing to ask the required questions. Of course that puts them out there and open to criticism - often unwarranted. Sometimes patience with the layman that are working through their particular problem is in order. Not everyone knows what seasoned techs know. Of course that's why they are on this forum asking their questions...
