I've just acquired a 'new' Singer Handcrank which I think is a 15 98. I'm not overly sure of the model but I think it is that one. What I do know from the Singer dating sites is that it was made in Clydebank in 1936.
This machine has the tension knob on the side of the cover plate as you sit directly in front of the needle as opposed to the arrangement which I'm more used to of the tension disc being on the front of the machine. This machine didn't come with a manual so I've had a pot shot at threading it and the stitch is wonderful but I have no real idea if I am threading it correctly.
So dumb question time; since the stitch is even and it's sewing beautifully, is that an indication that I've threaded it in the right way? Would I get crappy stiches if I'd taken the thread through the wrong path through the tension discs, check hook, check spring etc? Does anyone know of a cite that shows threading for one of these old machines?
I am going to buy a manual, but I'm itching to give it a more thorough test drive before that will have time to arrive here from my usual supplier.
