So I needed a way to keep a rolling game chair from pivoting/rolling away from using my Crosswinds. I'd seen straps, wood blocks, bungie cords, even tube socks over the wheels, but I wanted something cleaner looking and easier to use. This is about a foot and a half of PVC pipe, two T-fittings, a joiner, and of course black spray paint (material cost probably under $7-$8). It's rigid, stops rolling and pivot (measure twice, cut once, nice and snug against the gimbal), just snaps on/off my Wheel Stand that holds everything else, and stays on the chair when not in use (just swings to the side out of the way). Anyway, sorry for the shit pictures, but thought this might help someone out. :)
