John Tuttle posted the question about whether we should make use of
paper gaskets a standard procedure when rebuilding.  Our observations
on thin gaskets in glued joints is that it makes disassembly much less
destructive.

We have found thin leather used in some places, and that is more or
less standard for me now when attaching pneumatics or in other joints
that may need to come apart later.  It will make it much easier for the
next person working on the unit.

The same thought used when rebuilding pumps where wood parts are glued
together has led me to use silicon sealant on some joints.  It is air
tight, but easier to get apart than good hide glue after it ages for
30 years.

Of course, if you can be sure you are not the next to need to disassemble
the joint in question, you can make the next person's job as hard as
you want.  I have even found white wood glue in pumps, and cursed the
previous rebuilder.
