Continued the installation of the throttle, mixture and prop governor cables, and also the cockpit quadrants.
1. Measured the prop governor throw and determined it was almost exactly 2".
2. Double-checked and marked the mixture and throttle quadrant control arms appropriately. Drilled and deburred the attach holes.
3. Began the process of feeding the control cables through both a rubber grommet and the gear tower, and then adjusting them to approximately the right protrusion into the cockpit. I also had to wrestle them into the proper relative position to each other in my triangle-shaped cutout in the gear tower, with the throttle cable at the top left, the prop cable at the bottom, and the mixture cable at the top right. I also had to further secure the wiring inside the tower to prevent them from being rubbed or nicked during all the wrestling. These cables are really stiff!
4. Began attempting to fit all three cable ends through the quadrant cable-holder. It became apparent that, although the current triangle hole in the gear tower would work for Vans smaller cables, my thicker, better-quality cables will need a bit more room. Two of the cables fit into the holder plate, and one did not, so I decided to enlarge the hole a bit. I pulled the ends of the cables out of the gear tower and used an edge-marking tool to mark a line about 1/8" outside the edge of the hole. Used a large round file to enlarge the corners, and began filing the flats away. I am actually going to try to fit the cables without filing all the way to the remaining line.
5. Prepped and painted the throttle arm with flat black paint to match the other controls.
6. Prepped and painted the rear seat throttle pushrod. [No photo.]
7. Because of the larger triangle hole, I filed a bit of material from the attach angle that will hold the forward edge of the throttle quadrant to the gear tower. [No photo.]
