Insert the wider end of a 3-foot tube
into a 3-way fitting. Next, insert the
narrow end into a 6-foot bungied
tube, as shown below.
Insert another 3-foot tube into the other
end of the 6-foot bungied tube. You
will now have a 12-foot length of
tubing, as shown below.
Repeat this process three times, and
assemble the resulting four 12-foot
lengths into a square. The roof frame
is now complete.
