Finished drilling the elevator horns - 3 hours

After talking to Vans Tech support. I will take some time to move the existing pilot hole I drilled further in. Realistically I can move the pilot hole 1/64" (0.015625"). That would allow a final edge distance of 0.320" on the opposite control horn. 

 I drew a 3/16" hole using a circle template on the existing pilot hole that I can use as a guide to help me "move" the pilot hole inboard.

 After a lot of time, carefully filing the pilot hole and checking with various increasing # drill bit shanks. I successfully moved the pilot hole down and I am left with a #14 hole. Using an oak block clamped in between the horns, I used a #14 drill bit by hand and turned a pilot hole in the opposite horn. Sure enough...I have now a marker for the hole that measures 0.0320". Not perfect...but a darn good recovery. 

Then I very carefully reamed both holes to 3/16" and the AN3 bolt fit is tight.
