Hi folks,
I'm trying to build a release for a linear actuator to suddenly fire a weight in one direction. I have a motor attached to a long screw thread to move the weight slowly in one direction. The weight is attached to a spring and so builds up tension as it moves. Does anyone know of a sort of automated "half-nut" arrangement or similar that will spring apart allowing the weight to fly back without having to engage with the thread?
thanks.
