My guess - and it is ONLY a guess - is about 8 pounds without the motors. I'm probably ballparking high at the moment. Once all of the details are filled in I will give you an actual weight including motors and shifting mechanism. All of this is very much in the preliminary stages.
Does anyone know how to stop a pneumatic cylinder at 6 specific, pre-determined points in the stroke??
Glad to share!
