[CAUT] Rinsing lacquer from hammers

I'll try this again. Maybe the pics before were too large.

Hey Fred
I believe Jack has seen this in an electron  microscope.  I will ask him if 
there is any picture avaialble, but  anyway... Even if lac, or thinner do 
not cause the felt to swel,l it is still  possible that the thinners/lac. do 
penetrate the fibers.  Don't think of  hollow as a straw or tube but some 
kind of spongy type matrix. Oh how I love  speculation!! SO exciting when 
I'm....wrong

I'm curious. I learned from Jack Brand  (during the Weickert felt trials) 
at Wurzen felt that wool fibers are  hollow, which is why they can hold so 
much moisture. ie rugs, sweaters  etc


Do they  swell with lacquer, or the various solvents associated with it? I 
don't  think so. In any case, drenching hammers in lacquer thinner, acetone, 
or  alcohol doesn't seem to make them expand, or leave them larger than 
before.  Water does make them expand and they end up larger than before.
So I don't  think we know whether the solids in lacquer penetrate the wool 
fibers when we  dope hammers. I have always pictured it as coating the 
fibers. And have wished  that someone would do electron micrography on lacquered 
hammers so we could  see.
