I thought I'd share what I've been learning about basic sewing machine motors. First off, I am self-taught, so not an expert and certainly don't know everything there is to know about small motors. If you see a glaring error, please let me know! This tutorial is simply to show the steps I've taken to clean up a couple of grimy motors and help my "rescues" run better. This is definitely maintenance for those who like to get their hands dirty!
First of all, you will need the following:
Cleaning supplies such as brushes, cotton balls, denatured or rubbing alcohol, paper towels, and so on
Catch all for small parts
Camera (very helpful to document your steps!)
Drill or drill press
400 and 1500 grit sandpaper (may find in automotive paint section) cut into 1/4-inch or so strips
Sewing machine oil
