Measure the radius to the last tower. Now calculate how far it is around the last wheel track. Measure how far the end tower moves in 10 minutes with the timer set at 100%. Now you can calculate how long it will take to make a revolution. A more accurate method would be to make a revolution at 100% and time it.
