racksmum, Treadles are very easy to sew on. When I was a little girl (started sewing about 12 yrs.) all I had to use was my mother's treadle. Used it for about 7 or 8 yrs. until I went to work and bought an electric machine. This vintage shop has renewed my interest in the treadles, now I am looking for one. Hope I am successful. My mother had given her treadle to my sister and when my sister moved, she probably gave it away.
