Step 3.
Stack the servo bracket on top of the base plate and attach them to a piece of wood using #4 tapping screws. Don't tighten these down all the way yet. Alternately, you can use four 4-40 x .375" screws and nuts if you are not attaching the base to a piece of wood.

Step 6.
Slide the "C" assembly into position over the ball bearing and servo horn. If you are constructing an arm kit, attach your ASB-201 (for A and B arms) or ASB-204 (for D arms) to the "C" bracket using four 2-56 x .25" screws. Otherwise, just attach the "C" bracket to the servo horn. Note, the bracket is included in the arm kit, not the base kit.
