Polylon Pouches and PVC Glue

A word about Polylon: The Moller Organ Co. introduced this stuff -- a
polyurethane coated nylon cloth  .005" thick.  Really tough stuff that
won't tear because of the nylon infrastructure.

I've seen it used in a few high-pressure Wurlitzer organs, so I know it's
regarded as tough stuff.  The San Filippo organ in Barrington, Illinois,
uses it on the pneumatics when they restored that organ, though I'm not
sure how long ago.  The organ is working just fine, according to
"piporg-l" participants.  I saw it being used 5 years ago when assisting
in the rebuild of another pipe organ's swell engine.

In relation to the organ work I've witnessed, it's glued using PVC glue,
which is possibly why Mr. Bullock used the adjective "dreaded" in his
text (or was that because of it's close kinship to Perflex? ;).

Try to take a pneumatic apart that you screwed up using this material/
glue, and half of the cloth comes off, the other half remains stuck to
the surface.  There were pieces of the nylon remaining embedded in the
glue.  It required solvent to loosen the gunk up, and a chisel.  It was
awful.
