Machine story: The machine was still standing in a small office in the corner of his carpenter work-shed. A 110V electro motor was mounted to the machine. It was complete and the motor was used for tabular transport as well. But the enormous weight and size made him hardly impossible to transport. We dismantled the motor and unfortunately the tabular peace as well. A quick check showed that the machine was fully functional!
