Take a look at this sewing machine bought by a friend in a local charity shop.
It’s a 1954 Singer 99k hand-crank with the most wonderful faux-croc case made by suitcase manufacturer Cheney.
Its delighted new owner was a little crestfallen when the machine refused to form stitches; the needle moved up and down OK and everything appeared to function, but her test fabric revealed only a disappointing line of holes and some straggling threads.
There are several reasons why this might happen. The thread quality might be poor, or the needle might be blunt (or of poor quality), or unsuited to the thread/fabric. I began by removing an obvious problem: a thread jam around the bobbin case. Then I gave the machine a really good brush to remove any unhelpful lint build-up and gave it an oiling with good quality dedicated sewing-machine oil, took out the needle (and found it had been inserted incorrectly), wound some Sylko onto a bobbin and tested it on a scrap of calico.
Lo and behold, she worked.
Just a little tension adjustment here and there and she was up and running again and ready to be used exhaustively by an 11-year-old eager to hone her sewing skills. Nice.
If you have a vintage hand-driven Singer sewing machine in need of some TLC, I’d recommend visiting Sid & Elsie’s helpful blog. These cast iron machines were certainly built to last and it may be surprisingly easy to get yours running again. You don’t need many tools: just a couple of screwdrivers and a small brush (the hammer there on the table is a red herring, by the way – if you find yourself wanting to resort to using a hammer, please take your sewing machine to a professional!).
It’s important to have a manual for your machine (to find out how it’s supposed to be threaded, for instance, and where to oil it), so if you don’t have one to hand, plug the machine’s serial number into the Singer website to find out your machine’s name/model/date of manufacture and seek out the appropriate manual on the internet. The last time I looked, you could even find some available for nothing.
