I have an old Reeds sewing machine. Metal body, nice & strong no fancy stitches just straight & zig zag, I use it for any thing that the industrials don't like, light work. ::)
It has a bobbin case that fits vertically, all of a sudden the bobbin thread has started jumping out of the tension guide (on the bobbin case) it all stays threaded up & sew's until I get an almighty jam up ?
I use decent quality thread & don't drive that fast :-[
Any bright ideas ? ???
