The idea I came up with is pretty simple. I was gonna use the top brace on the back of the blade & attach bushings on both sides then either one solid shaft all the way across or two separate shafts (one on each end) to attach the wings to. This way I could swing the arms up out of the way. I was thinking about using 1/8 or 3/16 sheet metal for the wings & 1/2X1/2 angle to frame around the wings for strength.
