leecopp Report post Posted February 19, 2017 Hey Guys, still having fun with my Seiko STH 8BLD3. I have a couple 16 oz spools of v92 poly of on my vintage stand which is about 2' tall. I have not used V92 much in the past and only on 4 or 8 oz spools. The black bonded poly (full, came with the Seiko) appears to be recent vintage and and does not unspool easily. The thread is fairly stiff and feels like it is breaking loose as it comes off, and drags quite a bit as it comes over the shoulder of the thread. It causes a crazy high "pre-tension". My first working solution was to improvise a thread guide another foot above thread stand. This reduced the angle of the pull off the spool and yields a much reduced pull tension. Seems to be working. Any thoughts? Junky thread (I had been using dabond)? Lee in Florida Quote Share this post Link to post Share on other sites
MADMAX22 Report post Posted February 20, 2017 In my experience when the thread starts sticking on the spool its done for as far as machine use goes. Even if the thread stand is adjusted properly you will still get the random stitch that pulls up top when ever the thread sticks, sometimes it will be like every 5 or 8 stitches pretty consistently. Not all bonded thread is created equal and there is no telling how old or its past life before you got it. Quote Share this post Link to post Share on other sites

Funny you mention that .. The label has "Old Heavy " penciled in .. Quote Share this post Link to post Share on other sites
MADMAX22 Report post Posted February 20, 2017 Forgot to mention atleast with bonded nylon black thread is notorious for having "issues" or should I say not playing well with sewing machines all the time. I need to restock, Ive got some older bonded nylon and probably a third of it started doing the sticking thing. One spool would stick just on one side and would cause a stitch pull up every single 8 stitch which coincided with the sticky side of the spool.

leecopp Report post Posted February 20, 2017 Whoops, just put on a different spool and everything is good. Ok, tossing the junky full spool. Thanks for comments. Lee Quote Share this post Link to post Share on other sites
gottaknow Report post Posted February 20, 2017 In the factory we simply rewind it onto a new cone with a really handy rewinding machine. It does 4 cones at once. Regards, Eric Quote Share this post Link to post Share on other sites
JimTimber Report post Posted February 20, 2017 Might just be the outer wraps got fused from exposure to something. Before you pitch it, I'd pull down some layers and see if the issue clears up. Quote Share this post Link to post Share on other sites

I gave up after I had a rat nest on the floor the size of a small pony. 54 minutes ago, gottaknow said: In the factory we simply rewind it onto a new cone with a really handy rewinding machine.

leecopp Report post Posted February 20, 2017 Ok, I tried both... spooled off a bit, then rewound some on some kind of factory spool from the antique mall up in georgia (looks like a shuttle bobbin?). Used a wooden dowel in a power drill. I have to be more careful to keep it from puddling at the bottom. Looks like it working fine, sewing with no dropped stitches. thanks guys Quote Share this post Link to post Share on other sites
