Idea is to have the knot land in the middle of the layers of leather, and if the thread is thin enough for the single layer to allow a knot to form in the center, if the tension is correct, you shouldn't see the knot. I was not so certain I had all the settings right and the thickness of thread small enough for it to do that in a single 5 oz layer. I am no machine stitching expert, as you can see, since this is one of the few things I've done with the machine, and the first thing I've done since learning the cam that drives the presser feet was 180 degrees out of alignment and correcting it! YinTx I don’t have a problem with thread tension when transitioning from 2 to 3 layers of 7-10 oz leather when sewing tack on a Cobra. Pretty much anything from 9-25 oz looks good to me with my tension setting. This video was very helpful for dialing in the timing on a 441 clone. The author is on the sewing machine forum here.

I actually have an entire thread on this for the machine I used to do this work, including the video you mentioned. @Uwe's contributions have been very useful.
