Port headrest conduit 1.

There are a lot of wires on the aft side of our port headrest that need to get into the fuse conduit.
I was fooling to come up with a conduit design, tainting my efforts at sneaking under the aft headrest cover, then sneaking under the plywood conduit cover into the fuse conduit. Alan who was also studying the situation, suggested to perhaps go "subterranean", (below cockpit module but above fuel tank). Hmm, a consideration, but didn't like idea enough to go forward with it. It would be hard to snake wires, and would weaken the CPM along the way. Without missing a beat he suggested to perhaps run a conduit through the back of the port headrest and come out through the outboard side, (right next to wire run). Using my normal logic to look for a reason to not do something, (especially when it is not an idea of my own!), but if you can't find a good reason, any good reason then you have to do it.
P.S. a conduit is going to be installed through back of port headrest coming out the outboard side! Great idea Alan!!
We selected a piece of black plastic sprinkler hose as used for wire run in wings. I even had a hold saw of the appropriate size close at hand.
One problem that needs to be overcome is how to drill on a 45 degree angle to surface and not have the hole saw walk outboard.
Here you see 1/4" pilot drill (with flat).
