Using standard techniques, the Skybolt fasteners were located and mounting rivet holes were drilled. The fastener holes were then enlarged for the studs.
All pieces were disassembled, deburred and smoothed.
All required machine countersinks and dimples were completed.
The doubler pieces were then clecoed together.
The Skbolt receptacles were clecoed in position.
The receptacles were then riveted in place, followed by all other rivets. I wanted the doubler angles to overlap so there were 3 different length rivets used.
