at le Goodwill yesterday, i picked up a nice old all-metal Juki Baby Lock serger. It was in the original box, with original styrofoam packing, all parts seem to be there, has the manual, it runs, and my Ma & sister, who know how to use sergers (i don't) are going to come over this week to help me determine if it runs properly. If it does, what are it's potential applications for gear-making? what can i do better with this machine than with my regular machine? My sister was really excited that i got it, but i'm still kind of ignorant about what it's potential uses are.
