While I ponder how to locate the door pin guides accurately (I thought I had an idea but it didn't pan out), I took the time to do some work and planning on the overhead console. So the major thing going through the console is air conditioning, which meant that I needed to install the vents. A 2" carbide hole saw took care of the openings and they were quickly installed but the thickness of the console will have to be built up a bit to keep them from rattling loose. The rest that goes up there is avionics - specifically, the oxygen delivery stations and the overhead lights. I laid out the position of the delivery units in the aluminum panels, and then added the lights and switches. The plates will be machined by a friend and I am adding NC solenoids to the lighting circuits; the switch will turn off the light which will simultaneously illuminate the switch in red.The rear lights go directly into the console but the circuitry will be on the panel where I can reach. The baggage light will have its switch near the baggage door instead of in the console, so you don't have to insert yourself into the airplane to turn it on. You may notice I moved the rear lights forward of my initial mark; that makes it the same distance vent-to-light as the front and makes the lights less likely to be blanked out by a head.
