Step B10 : (Similar to step 4) Slide the screw on the forearm subassembly through the
dampening discs, and secure with a nylon insert lock nut. The amount of friction can be adjusted
by tightening or loosening the lock nut. Start with the nut loose, and if the arm seems to wobble
a bit, you can tighten this joint to correct the wobble.
CAUTION: Don't over-tighten this! If the arm is operated with the mechanical dampeners too
tight, the servo WILL heat up and CAN be damaged!
Step B11 : Attach the 3mm bearing to the end of the arm using the 8mm long M3 screw, M3 nut
and lock washer (bearing mounting kit). Tighten the screw so the lock washer becomes flat.
