Hmm, I was using that size, but before I made the adjustment to the bobbin, I'll retry that.

Cobra class 4 Thread 207, needle size 24 I tightened up my bobbin a bit and started getting really nice stitches in the total of 16 ounces that comprise the belt. I had the tension adjustments all the way out just short of falling off and was still pulling the bottom thread up enough to be visible, so a little extra torque on the bobbin solved that easily and the stitch is nicer over all. I'm also trying to do stitches on the keeper which is a strip of the 12 oz Herman Oak, skived down where it passes behind the belt. I'm still pulling up a bit too much bobbin thread on a single layer of 12oz, but I'm hesitant to keep tightening the bobbin. My main tension adjustments are still nearly all the way out.

I only have the standard feed dog right now. The narrow plate I'm using doesn't use the feed dog, so its needle feed only. I'm getting a nicer looking stitch from the narrow plate/no feed dog but consistency was a bit of an issue. In retrospect, having used the machine a little more, I think I may not have had adequate presser foot weight on it. I'm definitely going to look into the narrow feed plate. Mind telling me which one you bought, from one of the two suppliers on here I'm guessing?

Noob here. I've seen people using both the standard feed dog as well as the narrow plate when stitching double layer gun belts. I like the stitch quality from the narrow plate but get better spacing consistency with the feed dog obviously. Any guidance on which I should stick with, or how I might improve spacing consistency with the narrow plate?
