I just found this awesome group a few days ago and am only up to page 35, so I've got a LONG way to go but have learned a lot so far. The only vintage machine I have is one that my mother made my baby cloths with. I got it out this morning and worked on cleaning it up. I did not take it all apart (am Chicken) but did the best I could and am happy. I myself could never make this machine work. Mom said I did not have the right wrist movement !
In the one picture I have placed an old iron so you could compare the size. I use this iron to hold down the end of my cutting ruler when cutting strips, so it won't slip right at the end.
Have always wanted a treadle machine and will now look a little closer at the ones I see at yard sales. Even if it is a really bad one just so I can learn with it.
