Tonight I final torqued the pushrod jam nuts, and then installed the first pushrod into the fuselage.
Before I final torqued the jam nuts, I made a simple measuring device to ensure I had the right dimensions on the pushrods. I installed a temporary bolt into a length of wood, and using this to pin down one end of the pushrod, measured the center of the hole at the other end. This seemed to work well, and after a few minor adjustments I torqued down the jam nuts and marked with torque seal.
Installing the first pushrod into the fuselage turned out to be harder than I imagined. It gets fed through from the bulkhead at the back of the baggage compartment, which is easy, but getting final torque on the nut was really hard due to the limited access. It took an hour just to get the one nut torqued correctly.
