Marked and drilled the F-840 elevator pushrod and the threaded pushrod ends, and riveted on the ends. I primed the pushrod and painted it light gray.
Finished assembling the mostly pre-made F-839 elevator pushrod by screwing in the appropriate rod ends. Here, I encountered a slight problem: The drawings specify a 30-1/8" distance between the centers of the rod ends. One end of my pushrod allows the rod ends to be screwed in only about 5/8" before apparently "bottoming out." The other end is normal, but the pushrod is still 1/8" too long with both rod ends screwed in as far as they will go. I might have to tap the hole.
Finally, I drilled the 3/16" holes in the aft control stick that take an AN-3 attach bolt. This bolt secures the upper and lower pieces together, and allows the aft stick to be removed if desired.
