Has anybody done any experimentation on whether wool changes size with moisture absorption? There has been much speculation in this thread based on the felt changing size and I wonder if it really does? Just a passing thought. Jim Bryant (FL) >> If wool didn't absorb moisture and swell, then what accounts for sluggish centers? Is it the wood around the bushings that swell to tighten the center, or is it the wool that expands that causes the problem? I would suspect the wool. That is why can use a Protek, or the old fashioned alcohol and water, to ease the bushing. Or is that just to free up the wool, which is being pressed against the pin by the wood that is swelling?
