Dremel Moto-Shop 571-5 Scroll Saw Rescue

I found this Dremel Moto-Shop571-5 in a secondhand store for $10. It looked fairly complete but had no accessories with it. I don’t care about the accessories because I just wanted the scroll saw to function. Here is how I cleaned it up and put it back into service. I could not find much information about how to disassemble and reassemble these things, so I just had to make up as I went. Maybe this will help someone else – the reassembly can be a bit tricky.
