AboutTerry Expertise I Answer Sewing Machine Repair Guidence & Tip Questions Only.
I DO NOT ANSWER "Value", or "How To Alter", or "Sewing" Related Questions...period.
I can help on Singer`s 700, 600 series Touch & Sew`s, 400 & 500 Slant-O-Matic`s, and most older model Singers. Feather Weight`s (221 series), 15-91, 201 etc. I worked for Singer for 10 years, had my own repair business for another 10 years. Other makes entertained, but would rather stick to Singers of the older vintage. If you machine is newer than 1992, please do not ask me, as I am not up to speed on machines after that era. You might try the web site I have, to see if I do offer any advice there, but the focus in on those listed above. Feel free to visit my site: http://www.tandtrepair.com
Kind Regards - Terry

Expert: Terry Date: 7/3/2008 Subject: stitching with mod #774
Question WHEN I SEW A STRAIGHT SEAM, THE TOP STITCH IS FINE, BUT THE BOTTOM IS NOT STITCHING PROPERLY. IT LOOKS LIKE A TANGLE OF THREAD. IS THERE ANYTHNG I CAN DO TO CORRECT THIS?
Answer Hi Millie,
Sounds like either a top tension problem, or damaged bobbin case.
Best bet is to have a look at my free tips on thread tangling, bird nesting, in the bobbin area.
The link to this page of my web site is: http://www.tandtrepair.com/General_Tips.html
The 774 would fall under my 700 series T&S page of items, and the bobbin case for the 774 is on the Stylist pages.
Hope this helps provide the correct directions in solving the problem.
Regards,
Terry
