Hello again, Brett Mohr. With reagrds to your question about your
rebuilt bellows holding suction for 30 seconds vs Reblitz's 60 seconds:

If this is your first player rebuild, 30 seconds isn't too bad, believe
me, I've seen MUCH worse. However, Reblitz is right. With careful
rebuilding you should be able to get your bellows to hold suction for
45-60 seconds EVERY time. The really critical question, however, is:

    How long will your bellows hold suction when connected to the stack?
       
Try these tests.

First, disconnect all the hoses going to the lower bellows and seal
off all their nipples with duct tape. Pump the pedals until the
reservoir(s) collapse and measure how long they will hold suction. If
it's 30 seconds  or less you probably have leaks. Go down on the floor,
have someone else pump the pedals and listen for leaks. Once you're sure
you have the bellows as airtight as possible, connect the hose going to
the stack, tape off all the holes in the tracker bar with another piece
of duct tape, and pump the pedals until the reservoir(s) collapse. NOW
see how long they'll hold suction. If you did a REALLY good job of
rebuilding the valves, pouches and gaskets, the bellows should hold
suction just as long as they did BEFORE you connected them to the stack.
If there's a big difference -- say they held suction for 30 seconds
before being connected to the stack and only 15 seconds after being
connected -- you have problems, most likely related to the valves
not holding suction on their lower seats. Which could be the result
of not enough wobble in the valve, not enough dish in your pouches, or
even using too thick a lifter disk.  At any rate, a wide variance here,
means that your stack has problems. A stethoscope can be a big help in
locating leaks. Some people advocate sticking a piece of tubing in your
ear to help locate the leaks, but I feel more comfortable using a
stethoscope from which the collector has been removed. Summing up,
your player probably will work with a bellows that holds suction for
30 seconds, but if you have pneumatic rail lifters in addition to a
sustain pneumatic, your going to have to do some vigorous pumping to
use them all at the same time!

P.S. After removing the piece of tape from your tracker bar, clean the
bar with some naptha and a soft cloth to remove all traces of adhesive.
