Image 1 is a close up of me drilling the center punched shims that will be installed between the lower Flap Skin and the Flap Rib aft tab. Clamping the shims between the two pieces of 1x4 proved to be a good solution to drilling these small parts. Image 2 shows me deburring on of the Flap Ribs using a 2-incg Scotchbrite wheel in my pneumatic drill. Image 3 shows one of the shims clecoed in place between the lower Flap Skin and the aft tab on one of the Flap Ribs.
