Elevator Dimpling and Assembly

 Dimpled the front spar flanges of each elevator front spar.

 Dimpled the rear spar flanges of each elevator rear spar

 Dimpled the front spar webs where the inboard root rib attaches using 3/32 dies.  Did both spars.

 Dimpled the rear spar webs where the inboard root rib attaches using 3/32 dies.  Did both spars.

 Dimpled the flanges of the root rib for the skins.  Did both root ribs.

 Dimpled the root rib flanges that attach to the front and rear spars.  Had to use the pop rivet dimple dies for this due to no clearance.  Van's offers no advice on how to dimple these.

 Dimpled the inboard shear clips for both elevators using special dies made for 120° pop rivets.

 Dimpled the rib flanges for the skins.

 Dimpled the trim tab cable closeout cover reinforcement plate for the skins.

 Dimpled the tip rib flanges for the skins.

 Dimpled the inboard tip rib flanges for the skins.

 Dimpled these two holes for the tip rib assembly where flush rivets go to clear the counterweight.

 Same two holes on the matching parts of the tip rib assembly.

  I dimpled both of the counterbalance skins less the fairing attach holes.

 Riveted the inboard tip rib to the outboard tip rib on both elevators.  Had to use the longeron yoke for these.

 The front two rivets are flush.  Here they are all attached and riveted together.

 Then I riveted the counterweight skin to the tip ribs.  You start in the front and work your way around both sides.

Two tip rib assemblies ready to go!
