Had a visit from Jim Aqua, the Technical Advisor (TA) from the Experimental Aircraft Association (EAA). Jim is a member of Concord's EAA 393.

What did I learn from his visit?
1. I need to deburring the inside of the skin, at least the holes that aren't dimpled, since there is a burr on the inside. I didn't notice that before, but now I know what to look for.
2. I need to read up on “prevailing torque,” which is the driving torque required to overcome friction in a threaded fastening application, which produces no clamp load, or bolt stretch. Or, in plain (plane?) English, it is the torque required to turn the lock nut before I even start tensioning the bolt. If the bolt needs 18 in-lbs of torque, and the locknut needs 5 in-lbs of torque to turn it, then I need to have 23 in-lbs of torque to get it right.
3. If I am planning to spray Corrosion-X into the closed areas for corrosion resistance (that's my current plan), I should do it after it is painted since it will impede the painting as it leaks out.
4. We talked about where to store the empennage as I wait for the rest of the plane to be done. Probably in a semi-controlled environment, like my hangar or hanging from the joists in the storage area or the garage.
