I have been researching other machines that have external motor with belts: Necchi, Morse, and Singer 319W.
Purplefiend, you have me on a hunt. I saw a Singer 319W that has built in stitches and has the external motor. I wonder if this too can be converted to a treadle-that would be way cool if so. I also noticed that the MorseMZZ and the Necchi Bu Mira both look like they too could be turned into a treadle. Has anyone converted any of these machines to treadle? If so, was it easy to convert over? I would love to take a machine that has the decorative stitches and convert it to treadle.
