Isn't she lovely?
Its an older model: Singer Ultralock 14U234
I found this on Craigslist for $30! It turned out not to be such a great deal when I found that the cord sent home with me was the wrong one. I sent the seller an email hoping that it was just a simple mix-up. Nope.
I did find a used cord at a shop so I'm out a little more, but still a good deal.
If you've acquired one of these too, the owner's manual is available for free download here.
So. Now armed with the proper cord and the manual I sat down to play. Aaargh! With the tension set to the manufacturer's recommendations it looked great on the front but all wonky and loopy on the back. All of my tinkering with the dials just made it wonkier.
A few Googles later I found a random comment in a post about someone having trouble with the tension on their identical machine. This saint recommended the following combination for the tension dials:
Success! It works fantastic. Now what should I sew?
