The third floor grain elevator is a separate system from the main grain elevators on the fourth and fifth floors. It runs between the basement and the third floor and took in grain at the second street entrance. It used smaller buckets than the main elevators but we were able to repair it. The repairs required patching in about five feet of canvas belt and then we could make it run by turing the flywheel on the third floor. Powering up the motor was a bigger problem because the mill no longer has the 3 phase power the motor requires. After some research we found a simple converter that took our 220v feed and faked it into three phase. See the video below.
