With top skins done it is time to rebuild a wing cradle per plan. So I layed the wings on floor and bench, dismantled my wing fixture and reused the wood to make a cradle similar to ones on the drawing and that I've seen on other websites. I used my tank fixture cut-outs for the outboard end and a mere board to hold the main spar. Everything is 2X4s. I did not use any 4X4s.
