You can not put a Singer hand crank on the White but you can put a suicide knob (steering wheel spinner) on the spoke wheels. You can take a motor off some machines and treadle them. The belt has to fit next to the machine and down onto the treadle base. Some machines have a lip on the end and the belt won't go through unless you hack off some metal or something. Some Singers have channels you can run a belt through and treadle.
