I have used the rotator on Cub, Stearman, and Taylorcraft wings. It does save time, but I am not going to say it cuts it in half. It does make it easier.
I will take a look today if I remember. My airplane has cuffs, but I bet I can see from an inspection ring whether a bracket will work.
I stitch solo - I have perfected the art of looking through holes, or looking under the wing for the needle impression. I use only the Stitts hidden stitch. I rarely do Champ wings, and have not done an entire wing - but if I ever did, I would get one of those Milwaukee battery powered rivet pullers. Snap, snap, snap, and all done! We are always messing around in fuel tank areas, particularly on the right wing.
