SIG kits like that come with pre-cut shear webs, so it's difficult to get them going the wrong way. How the heck could you tell from a picture like that, anyway? You gotta get closer to see the grain.

Wood glue is fine, especially for a first kit. Lots of time to reposition, think, and double-check. Not only that, it sands easily, which can't be said for CA.

BTW, dbow, the wing is looking nice! :thumbup:
