Finally, after five painful months of soldering, unsoldering, resoldering, replacement pots, replacement wires, replacement reed switches and more, the right-hand jamb is finished. All 35 drawstops send the correct signal when drawn on, and again when put off. Each of the stops can be activated or deactivated by MIDI messages, which are converted into solenoid pulses. There are two 3-way rotary switches, and four pots, all of which send the correct messages when fiddled with. There are no stray messages being sent anywhere. It all works.

I need to shorten and/or tack up a few wires, but the work is essentially complete.

I have already prepped the left-hand jamb, to which I now need to solder 138 wires, but first I need to extend the 12V, 18V and GND lines across to the other side of the console.

Time to order more wire. By the end of the project, I will have used more wire than ITER.
