Re: The Portcullis Mystery
I read the field diagrams that the steel frame and polycarbonate sheet will *mass* more than 5 pounds, but springs in the side channels will reduce lifting force to just 5 pounds. This might be an issue to any mechanism that is trying to lift the portcullis quickly and inertia becomes a factor.
