Empennage attachment assembly torques

I added 14 inlbs for the friction of the locknut. I got that from section 5 of the plans where it discusses torques. Not clear from the table since the locknut column has a higher number to begin with, but the paragraph above the table says to add the 14 inlbs.
 
Measure the running torque of the locknut with a fishscale; add that to the recommended bolt torque.
e.g., AN4 torque should be 50 to 70 in-lbs. If the torque needed to keep the nut turning (not tight yet, but all threads engaged) is 14 in-lbs, then use 64 to 84 in-lbs as the final setting.

Or use a beam torque wrench. This is a good reason to have a beam torque wrench along with the clicker kind. Fully engage the nut and then look at the scale on the beam torque wrench while turning. It shows you the run on torque very nicely.
