Finally completed riveting the horizontal stabilizer, by using the 3x rivet gun to install the AN470AD4-4 that attached the horizontal stabilizer rear spar to the outboard HS-706 ribs and AN470AD4-7 rivets that attached the horizontal stabilizer rear spar to the inboard HS-00005 ribs. Then I used the squeezer (pneumatic and manual) to rivet the rear horizontal stabilizer spar to the horizontal stabilizer skin using AN426AD3-3.5 rivets. Finally I used the rivet puller to install the BPSQ-5-4 pulled rivets to attach the HS-603PP to the HS-708 rib and the horizontal stabilizer aft spar.
Next I primed the left and right elevator skins in preparation for their dimpling and riveting the elevators together.
