I broke the upper wing on my tiger moth and was wondering what is the best way to repair it. Ca or tape maybe or borh?
Thanks phaz

Probably a very thin layer of five-minute epoxy - be sure to keep it only on the actual surface to be glued.
Regular glues tend to allow flattish foam structures to "bend" at the break - NOT a great feature! The epoxy is rigid and will likely prove to make the strongest part of the wing.

Do not use CA on GWS foam......Do not use CA on GWS foam.....Do not use CA on GWS foam.....

Epoxy will fix it, just fine......Pat

Or you can use a polyurethane based glue (Gorilla Glue or Elmer's Probond or Loctite's Sumo Glue). Do not wet the surfaces (I bet that even in AZ there's some moisture in the air). Join the two parts and carefully cover both sides of the joint with mask tape. You will get a very light and strong joint that will be flush with the wing surface.

P.S. CA usually eats foam. There are some foam-safe CA types, but the joint will not be strong enough (long and narrow type). Epoxy or PU work much-much better.

Works like a charm:



Just apply and put packing tape over it. I put a light mist of water on my pieces before gluing and it cured better than when I have used it dry (repairing a coffee cup).
