A close up of the aileron set-up used to align the counterweight tube
prior to drilling. This is according to instructions, but may not
result in an accurate alignment of the counterweight to ribs. A better
way is to drill one end (both holes), then lay spar/rib assembly flush
on a flat table and mark and drill the other end of the tube.
The fun part-- back rivetting the aileron skins.
The flap table according to plans. It's flat and it's heavy.
My five foot bucking bar used as a weight.
Pea gravel in freezer bags. Easily recyclable, lead shot is not!
I used this modified screw driver to debur the inside of the stainless steel counterweight attach holes.
The trailing edge of the left aileron and the drill alignment jig.
Semi-completed ailerons in storage on air hockey table. This project is gradually taking over.
