[NSRCA-discussion] Wing tube phenolic repair "help"

[Ed Alt]

It's best to use the polyurethane glue as Bob recommended.  It's going to expand to fill the void and it's going to be alot lighter than epoxy.  I've done this repair successfully on 35% gas stuff and it really holds up well.  The only downside is that it's messy.  You have to either mop up affter it while it is catalyzing and oozing out of the holes, or else shave it off a razor later on. I think it's easier to mop & lightly sand when cured.

  How about a hypo and some epoxy?

  I was just about finished setting up my Odyssey when I noticed that the wing seemed a little loose. If I hold the fuselage the right wing panel can wiggle up and down a noticable amount. I thought that maybe the tube mount at the fuse was loose but that was not the case. As it turns out, the phenolic in my completed wing is loose about 3/4 of the way down and is wiggling around. It almost feels like the foam in the sheeted foam core wing has been somehow dislodged and the phenolic is in just a hollow cavern instead of solidly glued to the wing. It is still glued solid at the root so it won't slide out, but it obviously can not be flown in that condition.

   

  Question:

  How do I go about repairing the foam that the phenolic mounts to? The wing is sheeted, covered, and trimmed (complete) and I would like to keep from having to start all over again. Getting out the old one will also be an issue as it is still partially glued in. 

   

  I am open to any and all suggestions.

   

  Thanks in advance

  Anthony
