Re: Supporting 40lbs Arm with Motor?
we have a similar weight shooter/arm. Ours is counterbalanced with a gas lift spring like the ones used on car hoods. The arm itself is powered by a banebots 256:1 gearbox connected to a 18 tooth Gates pulley driving a Gate belt around a 50 tooth pulley welded to the arm. Works well .
