troubles with cb3500 threading on upper tension

[TonyGreen3455]

followed all recommendations  and on top of that moved thread guide before the upper tension a bit down, just below the axle of the tension itself - see pict. 
very happy with a result, whatever it's a right way or not. 
many thanks to all again.

That's the way it's done on the Cobra but if it works it MUST be right lol.

The funny thing is that when I saw this thread I found pics of how the Cobra is threaded and mine was totally wrong. I don't know how I was sewing anything with how wrong it was but it worked.

Ok sorry. I thought they both used the same threading path. 

This is a topic that I done sometime ago about the different top threading methods and may help. On my class 441 I follow the method of threading the top thread of the Juki TSC-441.

Also this path look suspect. You have the thread caught between the windings of the check spring, which adds tension in a spot where it shouldn’t.

Wow. Eagle eyed catch!

I had the very same problem with my Hightex CB3200 recently. It came from the thread... It was making pigtails when unspooling and when the pigtail arrived in upper tension, the thread was popping out... Try with a different thread and see if that was your issue

Here's one part of the problem of thread coming out of tensioners. I found out that not every spool of thread unwinds smoothly. Some, especially black thread spools are what I call "twisty or coily." They unwind with a twist that's in the direction they were wound in. The worst offender is from Weaver. Sometimes, thread is double-dyed to get a solid black color. This really stiffens the thread and can cause it to become a coil that twists around guides and jumps out of tensioners.

I have come up with a way to counteract this twist. This is specific to the Cowboy and Cobra 441 clones, and similar machines that have a top guide post containing at least two holes that are about an inch apart. My solution is to feed the top thread through the top hole, then turn it counterclockwise and feed it through the bottom hole. From there, it goes to the eyelet under the tension disks. I also lowered that eyelet to get a tighter feed into the disks. I've never tried feeding the thread back through that eyelet because my reverse feed seems to counteract the twisty thread.

This forum can be like a PHD in sewingmachineology.

I bet it's not the first time you've posted this but it's the first time I've seen it. So, thank you for it.
