So of course, my next question is "How do I set the motor speed?" Simple. One of these. <http://www.ebay.com/itm/261231971234> Set the "tire diameter" so that it reads something like 24.54 MPH for the actual speed of 2454.54 RPM. $7.49, how can you go wrong? Or just read the pick up directly with a frequency counter. Jeff-1.0 wa6fwi.
