Well.... On my last machine there was a 16barg supply and an 80mm diameter double acting ram with an 8kg flipper arm. The arm was fixed to the ram. I used the maximum cushioning at the end of the travel and still bent the body upwards around the lower mounting point. This time the arm is heavier and the forces are an order of magnitude higher. I dont want to rupture the ram or damage the body. That is why I am sticking to bungees to decelerate the flipper arm.
