Hello again All,  I am restoring a Seeburg "K" with an xylophone and
I have a few questions for the knowledgeable out there.

My xylophone has the external small pneumatics with the activating
levers that cover the bleeds on the backside of the xylo unit.  The
previous "restorer" (15 years ago) had recovered these small pneumatics
with the light weight rubberized cloth that was also used on the
striking pneumatics, and he had used silicone sealer (bathroom type)
to glue on the cloth!

Some of these smaller pneumatics seem to be rather hard to collapse.
Were these pneumatics supposed to be covered with an even thinner
material?  I need to recover these and want to do the job right the
first time.

The activating levers on the small pneumatics had a self-sticking
square rubber pad attached to cover the bleed hole.  As the xylophone
was not working when I purchased this Seeburg, I was wondering what was
originally on the end of the activating levers?

One last question:  What is the correct gap from the bleed hole to the
lever end pad when the pneumatic is in its open position?  I have the
stop strip attached over the pneumatics and when it is screwed down,
the pneumatics are collapsed to about 3/4 of their travel.  All of the
pneumatics still have the small spring wire attached to keep them open.

I have rebuilt the valves in the xylophone.  When I activate the small
pneumatics by hand to cover the bleeds, _all_ of the xylo notes
reiterate and operate correctly.  I have tested the piano valve chest,
and all the valve wells give me the same vacuum level output to the
xylo pneumatics, so my problem seems to be in the small pneumatics that
activate the xylo valves.  None of the small pneumatics are leaking --
I can see them trying to move, but some just cannot seem to close
quickly enough.  I would sincerely appreciate any suggestions.

Thanks to all,
