Hello everyone my name is Nancy and I have caught the VSM bug. I have recently purchased a beautiful 301A long bed that I will be using for quilting. My question is when you are sewing most days on this machine how often should you oil it? I have read that the VSM needs regular oiling and to keep it in tip top shape. I will soon be replacing the bobbin tire and light bulb. Anything other than oiling and needle that need regular maintenance?
