<DIV><FONT face=Arial> I have had good success in the past repairing foam
sheeted wing panels where the bond did not hold. I went to the drug store
and bought some insulin syringes (they have a fine needle) to use
that I could penetrate just through the balsa to the bond line. I
used thin foam compatible CA in the syringe and injected every
couple of inches in the unbonded area. This worked very well and
saved my wing panels. </FONT></DIV>

de-laminated ARF wing</DIV>
<DIV><BR></DIV>
<DIV>I'm looking for a good method for repairing an area of of sheeted foam
wing where it is not fully adhering, roughly 30 sq" in area. Current
thoughts are to try to inject some polyurethane glue just under the surface,
maybe a laminating epoxy instead. The tough part seems to be how to get
sufficient coverage right under the skin without going too deep. The
wing is already covered and I'm thinking that one method might be to use a
suction cup and gently pull the skin away to assure a gap so that a needle
would get the glue in between. Any thoughts on this?</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
