A quick summary of the week to date follows.
Installed brace channel for the ribs at each end of the trailing edge, filed and cut the trailing edge with a hacksaw carefully until the rib ends could slide easily inside and be screwed down with #4 PK screws. Then, the control cable path to the aileron was checked with more surveyor's string to make sure the brace from the corner of trailing edge and rib would not interfere when installed. Discovered the brace channel doesn't interfere with the control cable path, but the rib does; file to fit, will add a brace later.
Some of the docs we were looking through, trying to find voltage, wattage, amperage, and the charts and graphs for appropriate wire gauges when running wiring to the lights. We neither wanted to work out the long and complicated formula, nor resort to a "well, this is what a similar plane has" guess.
Checking the cockpit to see how the lights were wired to switches and bus, as well as circuit breaker amperage.
Running first batch of wires.
Hot and ground run to lighting bracket and out to wingtip.
Still to go: removed the fuel bay drag / anti-drag tie rods, as the thickness of the anti-chafe tubing was causing clearance issues. Swapped out friction tape and thick tube for lighter, thinner tube and shrinkwrap. Still need to heat the shrinkwrap very carefully with a torch, well away from any combustible sources, to overcome the heat sink that is the wire. I want it to stop raining so I can do that outside - we're experiencing the 8th wettest July in recorded history up here, and I am thoroughly sick of low grey skies and rain.
Also to come, not pictured, cutting the phenolic (must find my respirator) for a non-chafing brace & cable guide to rivet into the butt rib, a doubler for the butt rib where I had to cut it for fuel line clearance, and pitot-static tubing.
