Hi Pianotech folks, I sign on to this list occasionally, but don't stay around long. Frankly, I do not have time to sort through such a busy list, with so much chit-chat (often off-topic). Still, I want to stay in touch, so I sign on once in a while. To those who don't recognize my outrageous screen name, I am Frank Emerson, engineer for Mason & Hamlin, and formerly Dir. of R & D at Baldwin. I have been lurking for a while, but I cannot help but jump into this thread with both feet.

We take two samples from every soundboard as it is installed. I, personally, measure and record the EMC of each sample. I know of no other manufacturer who monitors the EMC of each and every soundboard. When we find the moisture content drifting one way or the other, we make adjustments, as needed, based on daily monitoring of the samples. We have humidity controls throughout the factory, but not as dry as we require for the soundboard conditioning room. From the time work begins on a soundboard until it is glued into the rim, it is returned to the conditioning room, when not being worked on. I will do my part to resolve the problem, but we must follow the proper protocol, and with good reason. To my friends in Indianapolis and Grandville, MI, I will see you next week. Frank Emerson
