Thread route through bobbin.

[toxo]

Saw this on a video short. Guessing it's a Cobra and noticed the thread going through the notch in the thingy that holds the bobbin in place.

Is this standard because I don't see any way I could do that on my machine? Of course i could always be missing something.

Yep. The bobbin thread runs through a slot/notch and under the tension spring on the bobbin case.

EDIT: I'm not sure what machine you have but when you drop the bobbin in, there will be an angled slot somewhere in the case. The bobbin thread will go into that slot *in the same direction that the slot is angled up*.  That notch you refer to should be the top end of the slot. Pull the bobbin thread up and out that notch. The bobbin thread then changes direction and passes under the spring.

Every machine I have operates this way.

Yes but I don't see a slot on the Cobra. It's where it goes after the tension spring that's got me puzzled? There's no way my thread can double back after coming out of the tension spring and go through the little notch on the bobbin retainer on the top like it is on the Cobra.

Gotcha, I misunderstood your question. That does seem a little odd.

I guess we need a Cobra guy to come along and say if it's right or wrong.

Come on you Cobra'ers! Is this normal or has it snagged in that position?

Thanks but there are lots of Cobra users on here and it's not a very difficult question.

That is correct for the Cobra Class 26 it does not have a Juki compliant bobbin assembly.

Here is a video for the bobbin installation.

Thanks Keith. Seems like a foolproof way to do it. I wondered if I was doing something wrong.
