Nope. Several reasons. First, while this is metal on the outside, it probably have plastic gears that are ready to evaporate at this point. (This is how power gets from the motor to the needle and the feet dog/bobbin assembly.) While “fixing it up” sounds great, you need a professional to re-gear the machine and then re-time it, or it won’t make a stitch. There are brand new machines that cost as much as an overhaul.

Assuming you got it working perfectly, you’re still working with something that was never designed to work with synthetic fabrics, can’t do chain stitching (which is what you want on anything stretchy and which will sort of approximate what a server does), and you’re missing out on all the things that are considered standard on a basic machine these days, like a self threading needle and electronic lock stitching.

The nostalgia for these machines is great and all, but this will cost you more money and more frustration than just buying a new, quality machine (like a mid-level brother). Unless this is literally “grandma’s old machine” that made your baby blanket, this is a hard pass.
