Change the bearings in the roller feeder to one-way bearings and throw some sticky gaskets over them and you've got anti-kickback as well as moar grip. Love all your ideas btw, esp the doweling jig using only 1 block of wood. Genius!!The first one is a great way of applying saw dust to your workshop!Great ideas, and good work. I have to say, however, my respect (not fear) of my tablesaw blade will never let my fingers get so close as yours.
