Stalled out on flap construction a bit as I took care of some misc items. The flap skeleton is just too big for the bench. Got back after it now that the right tank is pretty much done.
Deburred, prepped and primed the right flap parts. Also did the countersinking of the brackets for the double flush rivets.
Then got back to assembly of the left flap skeleton. Was able to squeeze most but there are several awkward rivets that have to be bucked with the double offset. Got the leading edge skin cleco'd on and back in the cradles, then cleco'd the top skin in place.
9/15: got all of the top skin rivets done with combination of gun, back-rivet and squeezer. Flipped it around and got the bottom skin cleco'd in place, then went ahead and set half the bottom skin to spar rivets. I was anxious about that, but picked up a tip somewhere to put tape over the trailing edge dimples to keep them from tearing up my knuckles. What a difference that made. It was actually a breeze. Very happy with the quality; I've come along way since the practice kits.
9/16: got the bottom spar rivets finished and set the pull rivets for the leading edge except the ones adjacent to the brackets. I need at least a 6” drill bit to reach those. After my success with the double sided tape on the ailerons I proceeded with that method for the flaps. Got everything cleco'd down to the door with a little overhanging each end. Looks straight though. Will let it cure a few days.
9/21: got my long drill bit and finished the blind rivets in the leading edge.
