Aster LGB Frank S automated uncoupling hook
thingiverse
This is my attempt to create an uncoupling device for my Aster/LGB Frank S live steam locomotive. A frame is attached to the front and rear frame-plate, inside the existing metal coupling hook. To release a coupled wagon, the actuator is pulled down by a miniature linear servo (https://www.banggood.com/1-Pair-Goteck-GS-1502-1_5g-Analog-Micro-Servo-For-RC-Airplane-p-1112821.html). The actuator hinge pins are pieces of 1.75 mm filament. The servo is glued to the frame using hot glue. A small piece of metal wire connects the servo slider to the actuator. The servo travel limits need to be determined and set up in the RC transmitter. 04 March 2019: Initial design published. To be printed and tested.
