Man oh man, I was just looking at a 301 and thought it would sew through anything. I was wondering about that. I will get my treadle machine going this spring. I will have to move it due to it's location. We have property in the mountains in northern NY. I just visited the place trampling through the snow to get to the house. I went in and it was very moist in there. So that being said, I will lube, oil and move her next fall.
