My hobby is sewing machines and sewing leather and fabrics. Because of some older machines that broke one day, I took a closer look at the mechanics of the older sewing machines. By replacing some parts, I get to know the mechanics of sewing machines myself. I am far from a professional. I'm still learning too. I also infected my wife so we could get both old and newer sewing machines working again. I hope you enjoy my videos. I'm just not the big talker, I prefer to write.
