I keep thinking about the fact that arching rises and lowers with the season, and we have to adjust posts because they don't change with the seasons. Is anyone aware of experimentation with posts made in a way so they expand and contract somewhat with humidity changes? I know there's some debate over the material of the post, and whether it has a tonal effect. If sound travels faster along the endgrain of spruce, then it's an obvious choice. I've heard some well renowned people argue on either side of the question of whether more or less dense posts actually effect the tone. Me experience suggests that the material does influence the sound (I recognize it may be my expectations guiding my perception), but the arguments to the contrary have been compelling. If material choice doesn't effect the function of the post (within reason), then I would think that a grain orientation that has the endgrain facing East-West rather than Up-Down would cause it to expand and contract similarly to the changes in arching. Of course the most obvious structural issue with this orientation is the tendency to split the post, but I imagine a washi paper wrap would keep it secure. The other issue might be a tendency for the post to flex thereby absorbing some of the energy that would otherwise transfer through the post. In any case, I probably won't make it back to weigh in on this any time soon, but I thought some others on MN enjoy speculating on the subject. I'd love to hear any real experience related to post material choices.
