I was determined (to say the least) to finish the wing of the Cub i was working on last wkend.

however, being the typical teenager void of patience, i decided to foolow through with this plan on sunday evening, having put it off before.

now, i had already finished the other half of the wing and the first one's general outcome was nice, 4 sure, despite the one piece i accidentally sanded too much...

needless to say, i plowed ahead with the second wing, and eventually discovered the spar was too short for the rib at the end, about 1-2 mm, leaving a small indent in the rib where the spar went into the rib. i considered bending the rib inward to fit over the spar, but decided finally to just glue what was hanging over the spar and fill in the indent with sawdust.

comments?..............

I think I would put a 1/8 piece of balsa on the end of the spar and sand it to fit the spar, and glue the rib and sand the extra balsa to the rib so it looks like it belongs. Not enough to make a difference, but use a nice piece of balsa to fix the leangth instead of scabbing in a bunch of dust that will look ugly. The balsa will look like it belongs at least.

But I've built a few kits, repaired at least one dismembered wing panel, and made mistakes along the lines you describe. It seems like I'm constantly gluing things before they should be glued and having to improvise fixes.

I would suggest making a doubler for at least part of the rib and gluing it to the inside of the existing rib so that the spar will have something to attach to.

That would be cheap, very little effort, and if you use cap strips will be invisible.

Good luck.

If i'm picturing this correctly, you can fill the gap in with sawdust, but I would add some gussets to the outboard side.
