hi there people ,folks, ladies and gents just joined up after finding this great site the reason i'm here is my neighbor threw out some old sewing machines and after looking at them i decided to save them them from going to the tip i saved 1singer 99k a nice model a bit scratched up but runs well, and 2 pinnock fridor sewmatics both in parts and pieces well out of the two i seem to have restored one that looks complete but seems to need some final tweaking and from the odds and ends left over i built a rotisserie for the barbie out of one motor (don't crucify me it was too good to waste ) and now i'm looking for help or advice on how to set bobbin tension on the pinnock any advise would be great thanking you
