Having built my organ during the last three years, I didn't like
the idea of covering the action so that it couldn't be seen, so the
primaries and pallet chest were covered with a clear polycarbonate
sheet.  This has been ideal for showing how the organ works.
I dispensed with the back of the cabinet for the same reason.

Recently I had a pipe which of its own accord would sound.  Having
checked for leaks, adjustments were made to the primaries but to no
avail.  Then, by inspecting with a mirror, it was found that a pallet
was sticking on its guide pin.

Normally this would have been a big dismantling job, but I was able to
drill a small hole in the side of the pallet chest and, with a hooked
piece of wire, carry out some keyhole manipulation.  I was able to bend
the guide pin and cure the problem.  (I had to get used to doing things
in reverse through a mirror).

Had I not been able to see into the chest I doubt if the problem would
ever have been found -- the action of dismantling the chest would have
released the sticking pallet.

I am in the process of building another organ, this will also have
see-through panels, a little more expensive than timber but well worth
it.
