I can't seem to get my 441 to feed material straight. the material is making a clockwise rotation. While practicing on a belt strip, I had to really fight to keep it stitching straight. I lost the battle a few times.

I also noticed that the stitches were so tight, that it put a sever curve int he belt - no way I could send that to a customer.

Could this be a tension issue? How should I adjust it?

Back off the bobbin tension until there is a smooth, even pull, with a little resistance. Sew a text row of stitches on some same thickness scraps, adjusting the top tension as you sew. When the knots are in the middle, you're ready to go to work.

Wizcraft,

I knew you'd have the answer. That said, I'm a bit more remedial... Can you tell me how to adjust those two variables? I'm lacking a manual to go along with my specific machine, so I'm just figuring things out as I go with a lot of help from you guys.

I also noticed that pressor feet were not perfectly aligned. I'm not sure if this is an issue, so I took a picture (see below). Can they or should they be aligned better? Could this be the issue? It seems that with with every stitch the material shifts to the left a few millimeters.

I also had a wandering sewing issue. I had the correct tension, but it still pulled to one side and I had to careful guide it. So, I used one of Wizcrafts golden rules: "If it worked OK before, check the thread path, then the first thing is to replace the needle". Sure enough, the replacement needle cured the problem. Seems over the first year of use I had never changed the needle and it had developed defect that pushed the leather, ever-so-slightly off to one side.
