To convert you have to have a working treadle base and a machine that will line up with the hinges. A spoked hand wheel would be helpful and the wheel has to line up with the belt wheel. The zz machines are harder to turn than the old boat shuttle machines. Oh put the machine on the hinges and put the belt on it. Some are more complicated than that. Search Singer 401G and you may come up with a pic of mine. But it was special - not all can be done like that either.
