Brief Description: Position and pilot drill upper longerons
The marked holes are where I got ahead of myself. The will be dimpled and flush solid rivets will be under the H. T. attach brackets.
Set 2 x 2 steel tubes on table and clamped the upper longerons to the skins. I started by lightly clamping the ends and middle then tapping the edge in place with a small hammer. Kept adding clamps and repeating the process until it was in the right place and I didn't have any clamps left.
These clamps have two grip strengths, light when the lever is toward the rubber faces, strong when the lever is away from the rubber buttons.
