Match drilled the flap torque tubes. Used the W-706 jig to set the clocking per the plans. Pretty easy. Primed the inside of all the pipes.

Cut the first couple of UHMW blocks and trial fit them to the torque tubes. As expected, they are very tight. Will need to play with heating the blocks and/or chilling the torque tubes to facilitate installation.

Jumped ahead and trial fit the flap motor. Deburred the bracket pieces to be ready be priming.
