Work on the outboard leading edge (OBLE) sections started out by measuring and drawing a straight centerline down both of the pieces of J-channel stiffeners that I had cut last night. Then I drilled one hole in each stiffener on the centerline at the prescribed distance from the end.
Then I removed the blue vinyl from the insides of both OBLE skin, set the left skin into the cradle jig, and started clecoing the ribs into place. Next the J-channel stiffener was clecoed in by its one drilled hole, and then aligned the centerline through the remaining holes in the skin and match-drilled them all.
Next, I enlarged two existing holes in the skin, cut out the area between them, and then smoothed the new oval opening with files so that the stall sensor (lift detector) can later protrude through there.
Since I had a little more time, I took the left OBLE assembly off the cradle, placed the right skin in place, and clecoed in all of the ribs and the J-channel.
What's next? I'll need to match-drill the J-channel stiffener in the right OBLE, and then disassemble both and do some more deburring and dimpling.
