ZigZag Report post Posted December 26, 2019 I’m looking to replace my Seiko STW 8 (same as Singer 111) with a large capacity bobbin machine. I would prefer an older used machine and must be compound feed. i have used the Seiko LSWN before which is a nice machine but don’t see many come up for sale here in the UK Any suggestions? thanks Nick Quote Share this post Link to post Share on other sites
Pintodeluxe Report post Posted December 26, 2019 I'm not sure what you need the new machine to do, but if a big bobbin is your main requirement I'd recommend a Juki LU-563. It has an extra-large U style bobbin, and is a superbly built Japanese machine. They feel about 10 lbs. heavier than other industrial machines in the same class.

kgg Report post Posted December 26, 2019 I never really thought to much about bobbin size for the machines I have owned over the years other then there was never enough bobbin thread. The stuff always ran out when I least expected / wanted too. So since bobbin capacity is a major requirement of yours and I couldn't find any information related to bobbin thread capacity I did some calculations for the amount of thread that could possibly be on a bobbin for the Juki TSC- 441, Juki LU-563, Juki DNU-1541S and Singer 111W. What my numbers showed was: Machine Bobbin V92 Thread Capacity V138 Thread Capacity V207 Thread Capacity V277 Thread Capacity Juki TSC- 441 Style 33 118.67 yards 78.67 yards 52 yards 39 yards Juki LU-563 Style U 75.67 yards 50 yards 33 yards 24.33 yards Juki DNU-1541S Style M 53.67 yards 35.67 yards 23.33 yards 17.33 yards Singer 111W Style G 34 yards 22.33 yards 14.66 yards 11 yards I know the numbers may not be totally accurate but it will give some relationship between the styles of bobbins and their thread capacity. For your needs of canvas and bags I think the either the Juki DNU-1541S or a Juki LU-563 would do the job. I use a Juki DNU-1541S and fine that if I can stuff the multi layers of different materials under the presser foot it will sew it. kgg Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted December 27, 2019 There is yet another bobbin size in current production. It is the Adler XXL bobbin that is used in certain new models of Adler leather stitchers. By my reckoning it is even larger than the Juki U style bobbin. See this PDF for more details. Quote Share this post Link to post Share on other sites

The 563 is looking like a very interesting option. Thanks Wiz, I’ll have to look into this in more detail. A font of knowledge as always. Quote Share this post Link to post Share on other sites
