I have an industrial treadle from 1910. It's a Singer 31-20. It's a huge beast but I havn't actually used it yet. Still looking for needles and my DH wants to do some wood work on it. I use my Singer 128 handcrank for sewing. It can go anywhere and be used anytime. I love handcranks. I also have my DH's grandmothers treadle but that is stored at his mom's house.(She gave it to me but I have no room). I have another one that is ta friends garage waiting to be picked up. I just got a singer 15 in a parlour cabinet......long story and she is smooth as silk to treadle. I am anxious to get her going but I am sending it to my master wood worker .... my Dad. He does miracles with wood and I know that he will enjoy working on it this winter.
