need advise on Stinson Reliant Giant kit build
finished the tail feathers and started taking wing ribs from balsa sheets and found them warped and some cupped,I then lightly spritzed them with windex placed them on my saw table and covered with straight piece of plywood to dry over night.next day they were still warped,my 64 thou question is: should I mix 50/50 solution of Tight Bond and water and re-spritz or is there a better mouse trap. Thanks for any help Nick R.

Did you wet the cupped side or the belly side? You need to wet the cupped side to help it expannd.
You can also try the old wood arrow straightening trick. Lightly rub the belly side W/something concave in shape. It will compress the wood fibers on the belly side & draw the the cupped side out.
