Assemble left and right legs:
a) Loosen “T” nuts on “L” brackets just enough so that
the T-nut fits into the extrusion slot in legs without
falling off.
b) Place the L brackets on one leg first (call one bracket
the rear one and the other the front one. Use the first
leg as a template for the second leg to ensure that they
are at the same position along the horizontal bar. See
Figure 10-2.
3. Attach the vertical bars to the horizontal legs:
a) Fix the diagonal braces to the vertical bars so they
look like the base in Figure 10-3.
b) Carefully slide each vertical bar on to the horizontal
legs (you may have to adjust the T-nuts on the bottoms
of the vertical bar.
c) Make sure that they are aligned with the L-brackets on
the horizontal bar. Tighten the nuts in the vertical bar
and diagonal braces so the vertical bar is fixed firmly.
Figure 10-4 shows the finished side of the base, in
preparation for connecting the left and right sides with
a horizontal bar.

c) Tighten the T-nuts again.
