That's an interesting concept. I wonder how I'd attach something like this to my rails. This requires more research.
I don't really know much about gears (or rack and pinion). Anyone care to offer advice on pitch, pressure angle, or whatever, for this purpose? It looks at a glance like Amazon has some options, though they're a bit expensive. This might be a future upgrade.
