Thanks, Chuck > Hi Matthew, I just rebuilt an Ivers & Pond 5' grand for a customer last summer/fall and I can't stress my agreement with the others about making certain to add AC or at least a dehumidifier, maybe 2 to your shop space along with heat and of course insulation. The I&P I did was from 1909 and had a Wessell Nickell and Gross action, one of my personal favorites to redo, probably just because I've done so many. You may find the scaling doesn't match anything in Travis's book, mine didn't and we had to rescale it but it was worth it, the scale is very smooth now with Arledge wound strings, we had wound wire all the way to D3. Good luck, Mike -- I intend to live forever. So far, so good.
