Brief Description: Mount Vertical Stabilizer (Fin) 3
After making sure the fin was vertical and orthogonal to the HS, I drilled it. I used the ange drill to access the holes in the aft elevator stop thru the aft spar of the fin. I then bolted it here.
Next you adjust forward and aft slightly and make sure the hinges are in a line. Then clamp the forward spar to the bracket and drill the rivet holes.
