Wow, Joe, you lost me at "disassemble it." I'm too scared that the little spring will go flying! I don't have any Evapo-Rust... where do I get that? Do you live anywhere near Denver?
I'll see what it looks like when it gets here and see how it works... maybe the machine will sew fine and the rust is just ornamental. Then I can try some Evapo-Rust without disassembling it. A girl can hope, right?
