OK, I know we've all been over this, but as a newbie associate I just have to ask. When we apply an alcohol/water mixture to bushings to free up tight action centers, doesn't that work by making the wood swell up around the pin, compressing the felt? And then when the alcohol helps the water evaporate, the wood shrinks back? (Or do I remember this backwards: do we do this to bushings to tighten up loose ones?) And wouldn't a one-foot plank of wood get longer (and bigger in each outside dimension) as it expands, when soaked? Are you saying the outer edges would move away from each other, but the walls of the holes would also expand towards the outer edges? What if you drilled a hole near the edge and sawed it off through the center of the hole? Would the straight edge move outward from expansion, and the curved wall of the hole move inward? Just trying to understand this -- I know it's counterintuitive!
