This nearly killed me, I now understand why people spend the $600 on a pneumatic squeezer, the amount of force required to set these rivets is tremendous, I feel pleased that I have the job done, but I am glad there are not any more of the AN470-AD4 rivets to set using the hand squeezer at the moment. The areas without rivets, or the freee holes are where the ribs will go, once I continue assembly.
Rivets in the rear spar
And the side with the shop heads, wow these are hard to squeeze
