Mounted my wings on the fuselage. Yay! But my wings sweep forward 1/8"
Hi all
Ok mounted my wings. my rear spares are all the way against the fuse. and yes I used a flush 1/8" rivet above where the rear spare is. So no interference with rivets. But my wings sweep forward 1/8". I am thinking the only way to remove the sweep is to take the wings off and file the rear spare down say 1/32 or 1/16. But before I do that I wanted some feed back. So, is it ok to file the rear spare? Thanks Joe

Yes it's okay to do that. Just go slowly because it won't take much filing at all. There was another thread along these lines not too long ago if you want to do a search.
BTW, 1/8" sweep is within Van's tolerances. But you can get as close to spot on as you'd like. Just keep in mind the potential damage that might happen if you're going in and out with the wing bolts repeatedly.

See the thread started by jacksel on 1/9/15. Much of the same experiences.

Be careful. Removing 1/8 inch off the rear spare = 1 inch of sweep at the outboard end of wing. Larry

1/32"
You'll probably only need about 1/32" removed from each drag spar. That should bring them into alignment. Very common issue that is easy to fix.

I find it difficult to believe that 1/8 th of an inch forward sweep would make any detectable difference. The end of the wing is, what, 9 foot out from the fuse?

I trimmed mine a bit, as suggested, and my little bit of forward sweep was corrected easily.
