Completed riveting of left inboard top skin. Rivets into main spar wre backriveted by clamping the bucking bar over 4 rivets at a time and then backriveting from underneath. Skin to rear spar was done with the pneumatic squeezer until I got to where the reinforcement plate interfered and then I switched to using a mushroom set from the top side and bucking bar on the back. Skin riveted to inboard rib using pneumatic squeezer.
Also completed riveting the bottom leading edge skin to the main spar using the pneumatic squeezer.
Then I took the Decathlon out for some well deserved exercise on a beautiful Fall afternoon.
