Does anyone know of sources for flanges for winding with PVC?
What size PVC pipe should be used?
Schedule 40 (just in case we add a Dispose-All in the Solo chamber)?
 
Who sells ornamental carvings suitable for decorating a console?
The local craft shop offers a paltry choice of about six, & the
Woodworker's Supply catalog doesn't offer much more.
 
Has anyone come up with a really nifty system for managing the monster
cable between an electropneumatic switch stack & relay?  This 2/10 Morton
has a keying relay with 8 trays, each "key" in the relay has 20 contacts
wired, & each Solo tray has 20 keys.  This means a cable with 400 conductors
coming off each tray.  I'd like to place some sort of connector between the
the monster cable & each tray so that future folks could just disconnect
the cable & pack the tray off to an organ builder in the event of a problem.
The only thing I've been able to come up with is to use 50 pair phone cable,
run about 4 of them per tray to punchblocks (with D-connector Amphenol
connectors), & then punch cables from the blocks to the switch stack.  This
would come to about 43 punchblocks in this case!
 
I've found a source for mil-spec 200 contact high-density connectors, but
they'd be a nightmare to solder, & if they developed a problem - the next
guy probably wouldn't be able to scare up another.  Plus the things are as
big as your head (well, mine, anyway).
 
Somebody else must have thunk about this problem before me and come up with
a better solution!
