The long 3/16" rivets through th flap actuator spacers leave long tails after being pulled, so I cut them off using a dermel tool with a cuting wheel, then filed smooth. I then decided to take a little of the LE bend out of the skin for a better fit to the ribs. Did this by clamping a board to the table sandwiching the skin. It did'nt make very much diffrence, but is OK.
