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

[wgalligan]

Anthony,

It shouldnt move around if there was a false rib to support the end of the tube.   I have made a repair in a wing that had the socket damaged.  You can cut the width of the tube the full length on the bottom side of the wing and remove the foam around the tube that is damaged.  Cut a piece of foam the correct size and shape of the wing tube socket.  Use a 1" dowel with sanding paper wrapped around it to shape the foam for the socket.  Then glue the foam in with Elmers Ultimate glue (urethane glue).  After this has cured trim the foam down to the depth of the wing sheeting using a dremel tool with a router attachment.  Glue in a sheet of balsa to cover the foam and sand smooth, recover or refinish if painted.

  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
