First off, many thanks for the reupload. I was hoping you could clarify though, why in 1-Speed Drive (or 2-Speed Drive for that matter) when calculating you multiply by .0254/2 (radius conversion?) and then divide by .3048*60 (revolution per unit time conversion?). More specifically, where do .0254 and .3048 come from? I understand that .0254/.3048 = 1/12 (which handles the in-ft unit conversion), but...
