Drying pinblock before stringing

[Ken Jankura]

Cy,
If you could apply only enough water/alcohol to just wet the bushing cloth
and not the wood, the felt would swell up and then retain some of its
compressed state after drying out, resulting in a looser flange. The alcohol
is there to help the water penetrate the cloth.
