  "notes": "Steel gear rack (module 3, 25 x 25 mm) sliding in two painted U guides, brass pinion with 18 teeth on a shaft in two pillow block bearings, hand crank at the front. The rack pitch line is tangent to the pinion pitch circle, so the teeth engage correctly. One pinion turn moves the rack by 17 cm. Moving parts: 'rotor' (pinion, shaft and crank, axis Y, origin on the axis) and 'slide' (rack, moves along X).",
