Let's say I have a wing with no dihedral, such as this one:
And I decide that it really needs some dihedral. (Maybe 4°)
I am not
much of a craftsman. Before I started building foamies a few years ago, I'd never built anything in my life. So I have no table saw, no band saw ... no fancy tools of any kind.
I'm unlikely to buy a table saw ($money$) or try to build a precision hot wire cutter (*skill*).
Is there a trick to measuring / scribing a wing to cut at the proper angle? I cheap tool I might not know about?
