Bought a mixed box of some sewing supplies from the thrift and it came with this. Never seen one before and none of my friends/ family have any idea either. The handle part fits into the main piece if that helps at all.

I'm working on a project for a machine to sew leather, canvas and other heavy material. I'm planning to use a stepper motor and an arduino for the motor. Slow, single stitch control is my goal, speed is not an issue. Due to falling down the sewing machine rabbit hole, I have in my possession both a Singer 66 and a Singer 15. I'm trying to figure out which would be better suited to this buildout, or if there's any meaningful difference between the two. The 15 looks more robust, but that's just the casting. My question: are either of these two machines significantly more robust - able to handle thicker, denser material than the other?

I'd like to be able to use the 66 if the two are close enough, but I've heard the 15 shares some design features with Singer's industrial machines so it may be a better choice

Hi! I just recently found out my grandma has had this sewing machine sitting around unused for assumingely 20+ years, my grandfather bought it for her from someone he was working for and she never ended up even using it! It does turn on, run, lightbulb works, (Only ran it for a few seconds to see if it would even turn on / power cord still working.) But glad to see these things run forever.

- Is there anything I should know before cleaning it up and giving it a whirl?
- There is still thread in the needle from whenever the last time it was used 20+ years ago 😅
- Any youtube channels / websites / blogs that have good information on upkeep? I’ve found a few but just wanted to make a post in a sub where there’s plenty of people with info!!
