Machine assembly

One C-channel drive unit: stator, NEMA bracket, output gear, gear train and stepper. 4 per machine — 3 in the feeder plus the classification channel's. Screw joints: 4 × M3 × 12 mm countersunk hold the NEMA bracket to the stator; 3 × M3 × 16 mm socket/button head hold the stepper to the NEMA bracket; 5 × M3 × 8 mm countersunk attach the output gear to the rotor (the light post's 2 × M3 × 20 mm countersunk into the NEMA bracket live on the light-post assembly). The rotor differs by location (faceted in the feeder, finned in the classification chamber), so it is not part of this node.
