Today I started off by match drilling the flap reinforcement brackets to one another and to the end rib/flap spar. I had to use the long #30 drill bit to drill the 3 rib flange-to-spar holes. Worked well. Used normal length drill bit for all other holes. I then disassembled all parts and started deburring. Got all parts complete except the L & R Flap top skins...will do that next. I also installed the K-1000-4 platenut on each L & R flap end rib. I also used the machine countersink to c/s all holes on the top rivet row of the flap spars.
Cleaned shop.
Next...finish deburring top skins & finish all edges.
