As I mentioned before, after getting a copy of Craig Brougher's great
book, the Orchestrion Builder's Manual, I was so dissatisfied with my
built-up nickelodeon, I ripped it apart and started from scratch.

By the way, many months ago I mentioned an experiment I tried with
filling the cracks in my soundboard with thick cyanoacrylate glue
and sanding it smooth before refinishing the board.  After numerous
fluctuations of temperature and humidity, the repair appears as good
as new and is solid as the original: no recracking or separation is
obvious.

My real question has to do with building a muffler for my PPCo suction
box.  Craig shows a muffler with a tube inlet, and I'm wondering how
I can effectively interface the PPCo box with a muffler.  The box is
designed with a slot for the exhaust that does not lend itself to
connection to anything.

I'm wondering if I should rework the exhaust, plug the slot and add
a flange, or build another box.  Does anyone have a design that
incorporates the box in a satisfactory arrangement?

I'm planning on building a muffler along the design of a car muffler,
using switchback baffles that pass a matching volume of air into
decreasing sizes of more numerous holes.

I also am thinking of using particle board and lining the interior with
carpet bedded into a thick layer of silicone glue so that the sound is
absorbed into increasingly dense materials.  Does anyone have a
sure-fire design he or she would care to pass on?
