I just made mine out of basically a 4x4 post, with some triangular feet I made out of part of the shipping crate. That supported the tip. I supported the root-end with a 2x4 nailed to a wall, onto which the spar rested. My twist from tip to root was under 1/16", so the wing with the pre-drilled holes do not require a fancy jig to maintain alignment. Now, the feet stick out and I did trip on them a few times, so be sure to clamp down the wing spar at the root end tightly.
