Are there simple devices that can be used on a table saw and applied to the top of the board to hold it against the fence - thus replacing the function of featherboards ? When ripping a board on a tablesaw, a featherboard is often used to hold the board against the fence. A limitation on featherboards is that they must be used on the in-feed side of the process because if they were placed against the edge of the board on the out-feed side they would press the two strips of wood that have been cut apart back together and pinch them onto the blade. I can visualize a motorized device that presses a spinning wheel against the the top of the board and uses friction to push the board against the fence. That may be simple from the commercial point of view, but from the "home owner" point of view it would useful to have an un-motorized contraption. Do such designs exist? When I visualize a un-motorized rubber wheel pressed on the board with its axle is at some angle to the plane of fence, I don't have an intuition about what it would do.
