Removing Rivets From Front Spar

Todays task was to finish removing rivets from the front spar. When it was removed from the wing the rivets were drilled just enough to get the ribs off leaving all the holes plugged with the ends of the rivets (I'm not complaining). For the 3/32" rivets holding the leading edge and ribs a light tap on the drilled off end with a hammer and punching them out with a pin punch worked fine and quick. For the 1/8" rivets in the doubler at the strut fitting I drilled them with a 3/32" drill most of the way through the spar and the punched them out with the pin punch. They just hung up to much with 3 layers of metal to punch out otherwise and I didn't want to increase any hole sizes. I also removed the strut fittings and the drag wire fittings. They'll have to go back on after the ribs are riveted on.
