What wheel size were you thinking of using? It looks to me like your final gear ratio will be 1:30 with somewhere in the vicinity of 75-85% efficiency (assuming 92-95% per stage). So, given the ~4500rpms of the chips under normal load, you're looking at around 2 rotations per second on your wheels. Multiply this by your circumference and you'll have a rough estimate of your speed. Assuming 6" wheels, that comes out to around 3fps. While this is very slow, you would have a lot of torque. On the other hand, bigger wheels would result in faster speeds (at the cost of torque) while smaller ones would result in even slower speeds.
