if you hinged one side of your motor to the base---you could just lift the other side of motor to easily change speeds ---and the weight of the motor would tighten your belt tension on the pulleys---you could make a multible step pulley for the motor shaft and easily have any speed ---if you make your hinge on a rod then you could move your motor in or out to align your belt under your upper pulleys to your lower pulley step----this method works very good and is very simple----I have done this with motors and step pulleys on grinders and other machines to make speed changes very quick and easy and inexpensive--just the weight of one side of the motor tightens the belt tension just right----make a 4 step pulley for your motor shaft and then you will have 8 speeds and easy and quick to change-----Dave
