[NSRCA-discussion] Carbon wing tube question

[White, Chris]

I'm taking the liberty of sending this alternate method which I thought
was really slick from Todd Schmidt awhile back.... Chris

Need a tool less way to attach wings?  I use a threaded end rod
protruding out of the wing root in the center of the airfoil.  Screw a
Sullivan spring-loaded ball joint on the end and clip them onto the
balls  mounted on the inside of the fuselage .  No stress on the
fuselage sides, no need to drill wholes in the tubes, best of all, no
tools needed to attach your wings. Simple, fast, positive!

After drilling the hole I take some little layers of 1/64" ply and CA
into
position, which easily bend to make the curve (2 or 3 pieces), then
drill
and tap.  I hate to buy an expensive carbon tube, just to add weight to
it.

I use pvc pipe. Cut a 1/2 inch piece that is just bigger than the tube,
then
cut a slot lengthwise so it will compress and push it into the end of
the
pipe. Align with hole in the wing and drill and tap for 4-40.Done
If the tapped hole wears out just rotate the pvc and redrill and tap
again.
