Center Pivot Base
2-56 Button Head
Alum Pivot ball
4-40 Thin Hex Nut
4-40 x ½” FH Steel
Washer
Assemble the Molded Center Pivot assembly as shown. Tighten the 2-56
button head screws [4] enough to remove any up and down play, be sure the
flanged pivot ball [2] pivots freely.
*Note - Sometimes it is helpful to
over-tighten the screws, then work
the ball around by hand, and then loosen the screws so the ball floats around
very free. Do not over-tighten the screws too much or you could warp the
pivot socket.

Red Locknut
1 - Place the 4-40 x ½” screws [5] through the graphite chassis [6] in
the holes shown. Tighten a 4-40 thin hex nut [7] down fairly tight.
2 - Then, after both thin hex nuts are tight on the 2 mounting screws,
drop the assembled center pivot over the screws. The assembly should
slide down over the hex nuts, not sit on top of them.
3 - Drop a washer [8] over each screw above the center pivot
assembly.
4 - Thread on the 4-40 red locknuts [9]. Do not tighten them yet as we
will adjust this in a later step.
