For years I have performed all of my experiments on a 5 ft wheel, cut from a single sheet of 3/4 plywood that was 5 by 10    available through Home Depot special order desk.  I used my CNC router to drill all the holes....... now with many many new holes.  Recently I have bonded two 4 x 8 ft sheets together and built an 8 ft diameter wheel and it has much different characteristics in its action.  I can now see the building of my 12 ft wheel which will open new doors as well.  I am currently building the components for the " working Bessler Wheel ".     I hope    Time will tell the Real Tale    but it sure feels good.           I am a Perpetuum Mobilist
