In the video where he explains that rotation, to me it doesn't look like the chains come down mounted in the same axis as the router bit to form a V, just a little higher. I just wondered if that by its nature is imparting a moment on the router. I wonder if you could mount the router on a bearing, have each chain attach to a free side of the bearing so each side can rotate around the router. Then just figure some way to lock the routers torque that isn't the x/y control mechanism. Perhaps 1 chain pulling directly down.
