Completed PF331 by de-burring and priming all pieces, cut out to go around strut attach pieces and left it in cleco's. Flipped the wing back over and installed the leading edge pieces and riveted the top portion in place, flipped it over again and clecoed the bottom portion in place, the bottom is pulling hard on the cleco's, when I rivet it in place, i'll have to use washers on the bottom of the rivets for strength. I made a note on the bottom of the wing as it will be some time before final rivet it.
