In preparation for attaching the tail section to the fuselage, I installed a wiring conduit from the tail up to the aft baggage area. In order to minimize the proximity of current-carrying wires to the GRT magnetometer at the top of the aft fuselage, I elected to keep the conduit run relatively low, rather than use the existing bulkhead pass-thru holes near the top longerons. This required creating a couple of standoffs for the conduit. The aft one is merely two tiewraps clinched around each other. Going forward, the next attachment point is made of two 1/2" angles riveted together, with a teflon tiewrap anchor screwed to one of them. Next, the conduit passes through a 3/4" hole in a bulkhead flange. The conduit ends here. Forward of this, wires will turn downward and pass through an Adel clamp bolted to a piece of angle riveted to the longeron.
Squeezing into the aft fuselage is really a chore for me, and I'm very glad this particular job is over!
