Brief Description: Main Skins - Locate and enlarge Tie Down Hole
I used a square to make the lines on the skins that will intersect at the hold down ring hole. Then I reapplied square after I put the leading edge on the wing and used the square to find the tie down hole. Turns out the pilot hole was very close. I'm not sure this line intersecting process is really needed, because you can look inside the leading edge and see the pilot hole within the circumference of the tie down bolt hole. Then I used a step down drill and Dremel tool with little side drilling bit and sanding drum to enlarge it and center it. Hole is 3/8 and the tie down ring fits right in. Later I'll figure out exactly what to do to seal this hole with or without the tie down ring in it.
