2003 Millie - L bobbin to M bobbin conversion

Recommended Posts

Got this reply back when I asked.  "With the age of your machine and the style of gearbox, it is not recommended to use the bigger bobbin. The hook size is much heavier and the bobbin only holds ½ more bobbin and the gearbox shaft wasn’t designed to hold that size of bobbin"


I may still try it in the future but for now will stick with the L size. Unless someone else tries it first and it works for them.

I don't want to argue with the folks at the factory but, I have a 1997 Ult 2 that I converted to M hook nine years ago without any apparent problems.  Now maybe quilting only 500 quilts on it since the modification isn't heavy enough usage to reveal a future problem I will have, but I'm not worried.  I can't believe that my gear box is heavier than your Millie's, so unless the gear boxes are in fact different, I'd take the chance.  Jim
