Attach the counterweight shaft by screwing it in to the end of the cylinder assembly adjustment (also
shown by the arrow in Figure 52). This counterweight shaft can be screwed in and out as far as needed
to balance the RA axis while also keep a low profile. Two possible options are shown in Figure 53.
There are two different counterweights included in the accessory kit, a 3-pound counterweight (a little
under 0.5-inches thick) and 6-pound counterweight (a little under 1 inch thick). There are also white
Delrin™ washers and low profile hex nuts. The washers are for protecting, as well as keeping the
counterweights from getting stuck together. The hex nut prevents the counterweight from being
accidentally removed completely. The second counterweight has been included to use at the other end
of the shaft if the entire length of the threaded shaft is needed to achieve balance.
The white Delrin washers must be placed between each counterweight before
tightening. If a washer is not present, extreme force is required to separate them.
