Began work on running the wiring through the cockpit to the aft sections of the plane. The Zodiac model has a natural channel along each side of the cockpit up under the upper fuselage longeron doubler. While there's lots of room under the doubler, securing wire bundles can be a bit of a challenge. I came up with a solution.
I fabricated what I'm calling wiring brackets from scrap, 5-inch-long L-angle pieces. These brackets perform 2 functions. First, they provide an attach point for adel clamps that run up under the longeron doubler. Second, they provide a mounting surface for nut plates so that I may attach the aft interior side panels to the ribs.
In short, I'm attaching one wiring bracket to each of the 4 major vertical structures on each side of the cabin interior: 2 x landing gear uprights, 1 x seat back side angle, and 1 x rear wing upright. I confirmed with the factory that drilling 2 x A4 rivets into each upright would have no structural impact. Today was mostly figuring out the fit and positioning, but I came up with a workable design and finished 2 of the wiring brackets on the pilot's side before the temperature crossed over into the 90s.
Wiring brackets attached to the two gear uprights. Will add 1 to rear wing upright and seat back.
Looking up under longeron at adel clamps holding wire bundles along the top of the gear uprights.
Test fit of the left aft side panel using nut plates in the wiring brackets.
