beltbuckles Report post Posted July 7, 2017 (edited) i have a juki 5550n-7 and it had some thread from the previous owner.. it seems to be really old thread and its super fragile and small.. the type for a home machine to use.. it breaks really easily.. so i loaded it up with some upholstery coats and clark thread nylon extra strong.. i couldn't find the size of the tread so i call the company but they didnt respond yet.. anyway it doesn't seem to be too big.. maybe size 69 or bigger?? anyway.. i loaded up the bobbin and the machine but the needle would not pick up the tread... hmmmmm i put the other small thread in and it worked okay.. again the "coats and clark" thread really isn't that big.. any ideas.. (here is a link to the type of thread for a reference) https://www.amazon.com/COATS-Strong-Upholstery-Thread-150-Yard/dp/B004BP43JE Edited July 7, 2017 by beltbuckles Quote Share this post Link to post Share on other sites
Gregg From Keystone Sewing Report post Posted July 7, 2017 V69 will work fine, but don't know for 100% if the under bed trimmers will cut that, or how well. First things I would check are the needle size, make sure you have a needle with an eye large enough to accommodate the thread, such as a size 18. Also, check the bobbin case tension, if it is set for fine threads, it may need to be backed off a bit. Other than that, should work fine, really unless something is wrong with the machine mechanically. Quote Share this post Link to post Share on other sites
