One collector's note about a 1976 Singer manual changed my whole repair process
I found a 1976 Singer sewing machine manual at a flea market in Portland last month. I was about to toss it since I mainly collect power tool booklets, but I saw a handwritten note in the margin from the original owner. It said 'always check the bobbin tension first, not the needle' after they had stripped a gear trying to fix a jam. So I tried that on my own stubborn 1980s Kenmore and it fixed the skipping stitch in like 5 minutes. Now I read every margin note in older manuals before I touch anything. Anyone else find hidden advice scribbled in their vintage booklets that changed how you approach a fix?
