> sewing machines today have a lot of plastic gears and other parts that do not last. Singer hobbymatic machines from the late 70s and later also have plastic gears, but for some reason these last no problem. They also mostly use bushings for bearings (I mean obviously it would make the mechanism much larger if you had to fit roller bearings everywhere), and they also last, provided you oil it every couple years.
