Brief Description: Flaps - Shimming aft end of ribs to folded spar
So then I made some 1/2 by 3/4 shims using the 0.040 shim material that came with these flap parts. I tried them in the gap between the rib aft end and the folded spar. Some places .040 was good. Other places felt like more shim was needed. But I measured the length of the ribs and they are all the same. The folded spar is straight. The aft end of the ribs make a straight line, so I concluded I couldn't put different width shims in here. I decided to make them all the same which is 0.040 inches thick.
I clamped them and drilled them. I recently drilled thru the side of my finger so I used clamps this time. I even bought a pair of gloves to wear during deburring. I'll add to the tools section.
