My Friend Paul R. made me the post for my wing stand. I have been holding off putting it up because it will occupy the space reserved for my truck. Life is tough. I mounted the post and fabricated the supports for the spar. When I was all done, it was late. I just had to hang the spar and ribs to see what I had accomplished. I did a quick check for twist. Without the skins on, the supports were adjusted for zero twist.
