loretta.lee Posted July 31, 2019 Report Share Posted July 31, 2019 I'd really like to swap out the "L" size for the "M" size on my recently purchased 2003 Millie .... can that be done? Is there a kit I can purchase? Link to comment Share on other sites More sharing options...
Sheltiemom Posted February 5, 2020 Report Share Posted February 5, 2020 I would love to do this also but I think it is about 3000 dollars so I am using my L size. Link to comment Share on other sites More sharing options...
jimerickson Posted February 10, 2020 Report Share Posted February 10, 2020 Sheltie: I think you're confusing it with some other up-grade. All you need is the appropriate M hook, M bobbin case, and M bobbin basket retaining "finger". Then it's just a matter of replacing the old L hook with the M, adjusting the needle bar height for the larger hook, and timing the machine.

jimerickson Posted February 10, 2020 Report Share Posted February 10, 2020 Just checked the APQS store for parts, and found the following: M hook: $215. M bobbin case: $54. M bobbin: $3, and M finger: $15. That's $287 total for the parts. Then it's just a matter of replacing the old parts with the new, and adjusting the machine to make them work.

Sheltiemom Posted February 14, 2020 Report Share Posted February 14, 2020 Thanks for that info. I will see if it is possible for my machine. I spend a lot of time winding bobbins! Link to comment Share on other sites More sharing options...
Sheltiemom Posted February 14, 2020 Report Share Posted February 14, 2020 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. Link to comment Share on other sites More sharing options...
jimerickson Posted February 16, 2020 Report Share Posted February 16, 2020 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 Link to comment Share on other sites More sharing options...
Sheltiemom Posted February 21, 2020 Report Share Posted February 21, 2020 Well I may just try it then. I can always switch it back. Link to comment Share on other sites More sharing options...
iquiltit52 Posted November 28, 2021 Report Share Posted November 28, 2021 I changed my Millie over to M from L 5 or6 years ago it worked fine all that time now I am having some issues and may have to have APQS check her out. Link to comment Share on other sites More sharing options...
jimerickson Posted December 7, 2021 Report Share Posted December 7, 2021 iquilt: What issues are you having? You may be up against routine maintenance. I had to replace the needle bar and bushings on my Ult 2, but things do wear out. I don't think it had anything to do with the M hook. It was a relatively easy repair.
