101537212Drive system The machine is electrically powered through a pulley system. This unit transmits the drive through 90 degrees to the gearing within the machine.
On some machines, the pulley could be replaced by a hand-crank.

101537213Overview The original electric motor doesn't currently work, and will be replaced or repaired at a later date.
In the meantime, it has been loosely re-attached and the machine can be turned over by hand.
The machine could originally be attached to the floor using four bolts - I've fitted it to a trolley to permit easy movement.

101538998Finished Compare this with photo 2, taken from the same angle.
The chrome finish is a little brighter than the original nickel plating, but was the best I could manage with local services.
