Help! My machine is misbehaving.

I opened up the machine and the set screw on the timing shaft has moved a couple of millimeters. (marks can be seen where it has been moved) I moved it back into the deepest mark made by the set screw and tested a scrap of 6oz. veg tan. It stitched perfectly, so I tried stitching the garment leather again and it stitched fine until I got to where the leather is folded over where seams join and it skips stitches again. It isn't birdnesting anymore, but it is skipping stitches.

Personally, I think that you're asking the poor little machine to do more than it was designed for. Realistically, you're getting into the realms of industrial machines.

I think you may have reached the limit of your machine, most of us have done it at some time and now it might your time to move to a heavier machine.

Sadly they are not cheap and I found the first one hard to justify, but you will be able to sew what you want to.

Many great people here will help you if you think you need more information.

Thicker seams tends to grab the needle and lift the presser foot on the up-stroke, collapsing the loop so the hook can't grab it.  Try increasing the spring compression on the presser foot.

I’d agree with others that your machine isn’t up to what you’re asking of it.

An older all metal domestic machine out of the 50s, 60s, or 70s can be found in slightly used condition at thrift stores for under $50 that is much more capable.

Better yet is an older commercial machine that can be had for almost the same price, but you’ll need to be a little mechanically inclined to get it adjusted - I see one every month that someone inherits or they are tired of and they just want it gone.
