Unfortunately, I probably won't have any results to report back for a while....
There were TWO bobbins with the machine!! (Plus the original manual?!! Plus 2 glass presser foot inserts!!)
Well, if I've inspired anyone else to give bobbin making a shot, please let us know. In theory, it should be very doable... My main concerns/questions are:
- Not sure about how the 3D print material will handle being spun and the heat from that. Will it gunk up the inside of the bobbin case?
- I really have no idea about the cost of getting these machined from metal. I'm sure it can be done... but I can also see it being cost prohibitive.
Anyway I'll be sure to post something on here whenever I get around to trying out this little bobbin production experiment. But that could be quite a while... I mean two bobbins? That's all anyone "really" needs, right? ;)
[1] A half-circle chunk, roughly 1.5" in diameter, is missing from the bottom center of the first 1/2 of the pages in the manual. It looks like a mouse found the book and thought it would make a good snack.
