Well as most instructions will say some tape across the wing
joints will keep them together.. When I epoxied my wings. I
applied enough epoxy in all areas, had towels soaked with
alcohol ready to clean-up the excess epoxy, once cleaned
I had made up a string of #64 rubberbands(2) just long enough
to keep good tension on the wing from wing tip to tip at the L.E.
and T.E. I also had two "C" clamps to keep alignment of the
wing joint at the L.E. and T.E. useing strips of bulsa as the feet.
This has worked great for me.. I also used some light grease I
applied to the feet for easy of removal after a day of drying time
with the wing standing braced good on the wing tip unmoved
