Started to rivet horizontal stabilizer (HS) HS-801PP L to HS-707L nose rib. Had to drill out several rivets because they were not “set” properly. Left the front and rear most rivets for the next day.
Just enough room to get an arm in between the skins to hold the bucking bar.
The Tungsten bar I am using is much heavier than steel bars normally used to “buck” rivets.
