This will be my first attempt at sheeting a wing, a foam core one. What do you all recommend i glue the 4"x48" sheeting together with i've read that CA is fine some say Titebond wood glue is better So far the plan is to save weight so the sheeted wings will be covered in Ultracote instead of fiberglass
after im done making the wing skins i plan on using gorilla glue to glue them to the foam cores
While you never asked the question, I would like to offer one more tip for you. Gorilla glue being an expander may or may not be a good choice - I do not know.
However here is a method, if you have the time, that will give you a sheeted wing that results in a well glued wing skin. I have used it for many years on both balsa and 1/64 plywood. Never a bump.
Prepare the wing skins however you prefer. I have used a SMALL amount of thin CA in spots on the wing side just to get the balsa skin together as the attachment method really glues the skins together. Whatever you prefer will work.
Mix any of the carpenter's alphetic resin off-white glues with water 50-50.
Brush the mix on both surfaces, wing and skin. Assure full coverage. Lay the skins on the core.
Place the wing and skins back into the foam cradles from which the wing was cut. Place on a FLAT surface. Make final adjustments of the skins to be in place.
Place every magazine, phone book or such weight you can find
on the foam. Don't crush things but a LOT of weight is needed.
After two days, remove weights and look at the ugliest balsa, black-like stains from the moisture, you will ever see. Let the wing dry out for overnight. Replace the weights and let things set for 3 or more days.
Now you will have a constantly glued skin and most of the ugly will be gone. After another couple days of drying it will all disappear. I have never had a wing develop a bubble even after in a hot sun all day.
Good luck.
