I would recommend that you pay careful attention to Bimba's dimension drawing on those 3-position cylinders. If you want the positions at something like 16", 14", 0", then the whole mechanism gets extremely long. My example there ends up a minimum of 30" long, unextended. As you can imagine, that's also going to consume a LOT more air, since you're basically pumping the a 14" stroke and then a 16" stroke. Back-to-back or side-by-side cylinders are a lot more air efficient if your application can work with them instead. With back-to-back cylinders, you can actually get 4 positions instead of 3.
