Now, for the industrial lego part: Pneumatic cylinders, valves, fittings, and pressure regulators are more or less all interchangeable, as long as you get your fittings and adapters right.

Co2 cylinders are basically the key to all things steampunk. Steam pressures at atmospheric temperatures. So you'll be hissing and making noise like crazy with one of these suits. But of course, you can route that escaping gas from the valves to muffled, padded places in the Suit, cooling you as you go.

Of course, we're gonna be Furry here, so this sucker is getting Digi Legs. Prestressed springs forming the Feet made like Recurve bow limbs, actuated with pneumatic cylinders. So, we've got powered springs for stilts.

With 800PSI on tap from the co2 cylinder, a lot of other actuation potential is unlocked. Most of these stainless cylinders can be pressurized to 400PSI, which means a 1" bore ram can exert 300 pounds of force.

That's a lotta force on an exoskeleton though, so proportioning and flow valves are Crucial.
