for Garden railways, G scale.
To fit to LGB coupling pin. Uses 1.7g micro linear servo. wire parts from 0.9mm and 0.6mm wire.
Uses 3mm dia by 2mm magnet to assist closing forces.
2021 update has revised geometry and LH and RH disconnect levers for the two different servo types.


V8 has slightly changed servo tang holes that should require less filing, and the main coupling has been moved 1.2mm laterally to make for better alignment when coupling on the track.
