Brief Description: HS-404 & 405 Ribs riveted to front spar
I thought I might have to buck the rivets that attached the HS-404 and 405 ribs to the front spar but the longeron yoke on the pneumatic squeezer made things easy. The ribs could be gently flexed out of the way just enough for the squeezer to work it's magic.
