Great idea, but it could become dangerous. I think it needs two spaced out bolts to hold to the slide in the saw table as this will prevent any rotational movement of the wheeled featherboard into the workpiece and also no matter how tight you make the single holding screw it will never be totally safe. Also rubber wheels would probably be better as they would give a bit more grip on the workpiece and allow for wheel deformation onto the workpiece as well. Still, great idea :)
