Sewn in! I killed the brittle plastic bevel gears on my old Singer 750 doing it, and had to finish the job with the GF’s Janome Sewist. The Taiwanese machine struggled with the heavy fabrics, but showed real advantages in having plastic drive gears that were only 10 years old, rather than 45. Parts are readily available for that old Singer, they have been ordered, and it WILL sew again!
Now I just need to get those lower stabilizer links (UPS says tomorrow) and will be 100% good to go!
