Jon,

How do they keep the force more or less constant on those gas springs? I
also considered pneumatic cylinders. However, like a regular spring, the rate
changes depending on where in the travel you are. I considered a regulator
but then you need a compressor to admit when low and the regulator to dump
when over pressure. Maybe if we got a really large cylinder and ran low
pressure.....
