Match drilled the U-804 inboard main gear attach brackets and U-806-1 inboard wear plates as per instructions.
Installed the gear legs using only the inboard 7/16 bolt and aligned the U-803 outboard attach brackets as shown in view A-A DWG75. Installed temporary 3/8 bolts in the U-803 outboard attach brackets to maintain alignment with the U-805-1 outboard wear plates.
We aligned the gear legs by attaching a 4' straight edge ("Ski") to the outboard face of each gear leg and then ensured that they were parallel to each other. We also measured from the tail wheel mount to each gear leg using a thin cable to make sure the gear legs are equidistant from the tail. I.e. square to the fuselage centerline.
After checking and re-checking all dimensions several times we first match drilled the 1/4" holes through the outboard wear plates into the lower longerons (which have less chance of moving) and then the 3/8" holes.
Match drilled the 5/16" holes through the inboard attach brackets / wear plates.
Match drilled the 1/4" holes in the inboard wear plates from inside the fuselage.
