Riveting elevator skin to bottom spar

[Fedico94]

Made and assembled a jig to rivet the elevators to the bottom of the spar. The uprights correspond to the cutouts for the rod end bearings in the skin, they are made from 1 inch square steel tube from local hardware store . Attached to this is a leangth of ? x ? steel angle. Each upright had a ? inch hole on the top to attach the angle and two ? inch holes at the bottom to attach to the table with lag or regular bolts
1/4 inch bolt cut off with Roto zip and use ot self locking nuts
The elevator is fed down the steel ? inch angle with ends of angle covered with electrical tape to prevent scratches. Then the middle two uprights are placed.
The 1 x1 x 2 titanium bucking bar is fed down the upper D cell of the elevator on a 5/8 square wood stick from Lowe's hardware (4 ft long) with ? inch notch cut out. This secured the bucking bar in place while it slid from each position to the next. note . the bar would hit up against the next adjacent Cleco and with visual confirmation of the bar in place the rivet was dropped in and the elevator lifted up to begin the riveting with 2X gun at 40 psi,
