Ok on with the wing build. Sorry I got my pics out of sequence.
Pic 2 showes the phenolic tube installed in one half of the wing.The long piece of tube will be trimmed off later. This is where I will be using gorilla glue to install the tube in the wing half. First chase a lightly damp towel through the foam wing hole to moisten the area where the tube will go. Put a coat of Gorilla glue on the tube and slide the tube till it sticks out past the liteply support block maybe 1/32".wipe up any squeese out immediatly.Place the wing half back into the "shucks" and weight it down till the glue cures. After it cures, clean any dried glue up with an Exacto Knife and sand paper.
Pic 3 shows how the tube will look at the spar support block.
