David, The things I'll do to avoid working. I dismantled the pedals from my 1920ish O. The thread looks like it might be 30tpi, since it is more than the 28tpi leaf and less than the next (32tpi) leaf, by what looks like the same amount. The screw diameter is .2125". I don't know when they changed that, or how often, but it is certainly not the current spec. What's the vintage of the piano in question?
