taking a warp out
 

I'm building a H.O.B. 1/2A mustang and the balsa fuse sides are
doubled with ply. After gluing the ply doublers to the balsa sides
(used alphatic wood glue and allowed the parts to cure under a
flat, heavy surface), they warped to form a concave surface on the
outside. How can I remove the warp?

Greetings Whstlngdeath: My thought is that the warp will work it's way out as the structure comes together. Always happy to help if I can. Garry

Same thing happened to me. I haven't found a great way to undo the warp either yet. Hmmmm

Hopefully the fuse formers will straighten it out. But you could try wetting the inside of the curve. That will cause the wood on that side to swell and push in the other direction.
