As you're securing the tubes into 6-foot and 9-foot
sections, be sure to make them as sturdy as possible at the joints.
Trust me on this one.

work. Keep it up fellas.

Now the assembly begins. With the assistance of lots of duct tape,
configure the 6-foot arms around the vertical 9-foot tower and secure
to roof rack. If possible, at the joint where the smaller arms support
the vertical column, allow some up-and-down movement so the structure
can wave with the wind. We don't want to be too rigid, after all,
we're here to have fun.

 Notice
from the top view, the perfect interface each supporting arm makes
with the column, using the triangular shape of the FedEx tube.

 This
is a good time to notice that, for this prototype, we did not follow
the exact instructions outlined in the blueprints. Where Rob calls
for three 6-foot sections, we used only 3-foot sections. (We ran
out; incidently FedEx tubes do a great job of holding up a tarp
in the conventional sense. Which is why I would bring extras!)
You'll see for yourself what this construction flaw
did to the final installation. (Continued on page 4, below.)
