We have used the Fiat car front wheel axle assembly with special mounting, We have only one set of compound pulley with vee belts which connects to the wheel tire holder which acts as a pulley. A standard 1400 rpm motor is used with a timer. The turn table speed is 65 rpm. The Rotating disc is a stainless sheet that is glued to 10mm Phenolic sheet. The Round shape was ground in-suit after fixing , thereby ensuring good concentricity.
