Julian,  Every Standard and Autopiano wind motor I have ever rebuilt
had no gaskets between the pneumatics.  I would think it would be a
good idea to put a thin paper or cheesecloth gasket between, just in
case you have to remove the pneumatics for some reason.

I had the misfortune of being stupid enough to glue the pneumatics
on in the wrong order.  The fingers did not line up as they should.
A quick fix would have been to reposition the fingers, but I wanted the
pneumatics on in the right order.  In short, I destroyed the surface
the pneumatics were glued to.  Had to recover all the pneumatics and
make a new mating surface.

If I had used some type of gasket I would not have had so much damage.
If I was really smart I would have repositioned the fingers.  Oh, the
joys of being ME!
