Note: This post is some of what we’ll be going through in the class I’m giving in William’s Lake next month.
The 401A, 403A, 411G, and 431Gs along with the 500A and the 503A (or the J version) are possibly some of my favorite Singer machines. There are a few more in this series as well, like the 401G and the 421G but I’ve honestly never laid hands on either of those models. These machines are all fundamentally the same with some small differences. They are all “Slant-O-Matics”, meaning that the whole stitching mechanism is tilted a little and angled toward the user to make the needle more visible.
Today, I’m going to talk a little about the differences and also about the one thing that makes some people shy away from these machines – the cam stack and stitch selectors are frozen. It’s typically easy to fix, so I want you all to know how to take care of it.
