The photos show rig made from 2 Harbor Freight 1000 lb Engine Stands with the legs installed on back side (without casters) and it clamped to a Hydraulic Lift Cart. Wedged back leg to get pivot horizontal. I also modified the Hydraulic Lift carts to have an adjustable stop for down travel to avoid leak back and to have more control in lowering the wing. The adjustable stop is basically a 1/2" thick x 1" bar held by an 1/2"-13 all-thread jack screw against the rollers in the scissors lift track. I also used counterweights on the lift tables to avoid tip over even though the carts weigh 100 lb each and the Engine stands are C clamped to the table. Checked for horizontal Center of Gravity location and guessed Vertical location before mounting Engine Stand Pivot. Came out well, wing would stay in any location without holding it through out the rotation.
The nice thing, is both the Engine Stands and Lift Tables can be used as normal afterward. Hopefully, the same rig can be used for fuselage rotation.
