Well, after conferring with the mother ship, I've decided to bite the bullet and re-do both aileron spars on my '7 build. Fortunately I have not riveted the skins on yet. Here's the result of match drilling the bracket through to the spar without properly securing the workpieces:
This is the left one. The right one is a little better but still way larger than the acceptable diameter for AN3 bolts.
Problem with drilling these is that there are only two holes, so while drilling one hole, there's only a single cleco securing the parts together. I tried additionally holding the workpieces in place with a c-clamp and a small piece of wood, but obviously the bit still walked around unacceptably. Anyone have a good method/tool for match drilling these correctly?
