Don't know what happened but only half of my post shows up. I went on to say that I have experience using a dressmakers model that was my grandmother's from when she worked in a factory in Brooklyn. This new machine is a 1921 15-30 with Tiffany decals. She seems to sew pretty well, still adjusting the tension. My concern is that she seems to run heavy. By which I mean is she is kinda loud and if I accelerate the whole table shakes. Any advice? TIA Donna
