Thanks all...I certainly do not need motor mayhem! I have a little controlled mayhem here anyway. I've just totally dismantled my 1909 Singer treadle for cleaning and refurbishing per Billy's tutorial. It looks pretty sad and "undressed" with all the parts laid out on the table. But it came apart easily, exactly the way Billy described! (Thank you!) Tomorrow we're off to the kerosene spa! I can't wait to see how it looks when it's all cleaned up.
