In the same way as the short beam
place and fix the long beams in
between the two structures. Place both
beams before securing them in place
as once one is in place the structure will
be locked in place.
Remember to turn the bolts anti-
clockwise to fix the beams in place.
Once complete check that all the
beams are securely fastened to the
legs.
Repeat this process with the remaining
leg of the pair, fixing it to the other end
of the beam. The result should resemble
this illustration.
Repeat steps 1-3 with the remaining
short beam and the other pair of legs.
You should now have two identical
structures.
