After fine-tunning rod end bearing distances, elevators were aligned in relation to the trailing edge on the extended chord line of the HS. Secured the counterbalance arms even with the horizontal stabilizer "in trail", or neutral position.
Fabricated a drill bushing using a small metallic tube with an OD of 1/4" to protect the VA-146 hinge bearing from the drill bit, and to act as a drill guide to locate and drill the holes in WD-605-1-R/L for the bolt that attaches both horns to the center bracket.
Using the above method, pilot drilled WD-605-1-R and then repeated the same process for WD-605-1-L.
