[QuadList] more air-related quad stuff

[bill.spencer at northstarstudios.tv]

I found a replacement for the vacuum gasket in the seals on a set of air
conditioning pressure gauges.  Also at either an auto parts or hardware
store that has a variety of o-rings for auto A/C or plumbing use you can
find one the right size.  The ones made of silicon rubber last longer
and won't deteriorate from the cleaning agents that get sucked in.

Roger,

Those gaskets for the Mark 10/15 in the photo came from Patrick Johnson
at Aheadtek.
www.aheadtek.com


Later on, I made a template from 1/8 inch thick flat sheet aluminum to
use with a razor knife to trace the cutout.
I had been getting that material and also the cork for reel turntables
at Michaels', a local art & craft retail store.
Anything close to original will work ok, its not that critical. The
small vacuum gasket needs to be more dense rubber material, because it
will tend to leak if it doesn't fit snugly and compress a little when
the head is tightened down against the transport.

I don't seem to have a photo right at the moment on the gasket making,
but I did make a reel turntable cork replacement a couple weeks ago on
an AVR 2 using the same template method.
That project is pictured at:

BTW, I found a good replacement tubing for the Mark 10/15 guide vacuum
hose at the local ACE hardware store.

Not sure where to look for the 3/16" foam.
