Hello All: I am in a pinch. I need to find a complete RPM set-up for an experiment. I have a bodine gear motor that drives a round table via a v-belt.I needed to know how fast it is rotating so I bought a bicycle odometer which I figured would tell me the speed in Miles per hour and I could do the conversion to RPM the problem is the table goes to slow and this cheap odometer wont register. My question... Does anyone know of a supplier of complete RPM systems that would work either on the shaft or at some radius on the round disk at 1 RPM. I have found plenty of parts/ways to build this but I just dont have the time. That you in advance for your help.
