This Is To My Fellow Cobra 4 Owners

[GoldenKnight]

Please post the solution when you resolve this issue.

I'm finalizing my research & savings and expect to buy a 441 clone, leaning toward the Cobra Class 4, ... however, for the cost of this investment, it would be reassuring to know this isn't a problem with the machine, but a setting issue of the user/operator.

Thanks.

There is a "fix". I struggled with the tension, thread drag, skipped stitches, and flat laying bobbin thread. So I started experimenting. The final result is no tension. Both spring nuts backed off all the way. Just enogh not to vibrate off. I thread through the top eyelet, then over the top tension disc (snap it in) and straight down to the bottom eyelet. Wind counter clock wise 3/4 of the disc and out to the "spring" eyelet and up to the take up arm. The rest as usual.

I adjusted the bobbin tension per instructions from Massive. I changed from nylon to polyester. 277 on top and 207 on bottom with a 24 or 25 needle.

Learning to tie off rather than back up.

Skipped stitches are history. I have no short and long sitches.

Just operator errors.

Price does not include handguns:)

End of discussion?

I believe that the Cobra 4 and the others will sew. I believe there are 927 ways to thread these machines to sew. I believe you have to find your combination. Needle, thread, tension, leather, lube,....heck, I have noticed when my thread hangs up on the spool even a little bit, it creates awful tension on the thread at the discs...if you have it threaded as from the factory. Kinda touchy sometimes. I think I have rid myself of most all the touchys.
