I am doing the initial fit up and metal work on my right elevator and I have a question for those that have gone before me. I searched the forums and didn't really find the answer nor did I find it in the several build sites I searched.
My question is this;
How are people drilling through the E-714 lead counterweight to end up correctly placing the holes in the E-703 and E-704 ribs? I can see where it would be quite easy to do it incorrectly and end up with problems. My first thought was to fit up the assembly, transfer marks from the pre-punched E-713 skin onto the E-714 counterbalance then break down the assembly and drill the counterweight by itself on the drill press. That will ensure the holes through the counterweight are straight. Rebuild the assembly and now mark the two ribs through the holes in the counterweight. Break the assembly down and drill the ribs.
Thoughts? Other procedures, tips, tricks?
