I was working on my flap pushrod between the actuator arms today and noticed the build manual recommended removing the torque tube and using a drill press (which I didn't have). It also recommended using the #11 drill bit (0.191") for drilling this hole out for the AN3 bolt. Instead of removing this, I elected to drill the holes while the torque tube was installed but using a 3/16" bit (0.1875") to drill the holes. Then I used the 3/16 Cleco (gold) to hold the pieces while I flipped the tube and drilled the other side. Ended up being snug but worked just fine to install the AN3 bolt for through the actuator arms and torque tube.
Also, it amazes me that an AN3 supports the full force of actuating these flaps between the torque tube and pushrod! Seems like a WHOLE lotta force on that tiny bolt... definetly wouldn't want to overspeed those flaps!
