It's not always easy to take off the treadle parts and still have a stable cabinet. The rods, nuts and washers mess up the stabiltiy when they are not in place. There's usually ways about it though. If it's a very nice machine and cabinet, all original and goes very well together you might consider getting an electrical machine in a cabinet made for the purpose in stead. On the other hand a 115 should easily convert to motor and lights, I think this model was made for it. If it has the fitting for the hand crank/motor bracket under the hand wheel it is (a treaded hole for a bolt).
