The Dreaded Timing Issue

[Tree Reaper]

I had a thread get jammed in the bobbin and I think the timing might now be out of whack.

The two pictures show the thread single and then with the arrow back stitched.

The single forward stitch looks good but when back stitched it isn't stitching in the same holes which leads me to think the timing might be out.

Any help would be greatly appreciated.

Thanks.

Kevin.

Kevin I wish I could help...I know Singers and only the old ones at that. They don't have issues like this. At the risk of sounding stupid, did you check to make sure your needle didn't get bent?

[Tree Reaper]

Needle is good but I have to check the needle to shuttle.

First comes the shuttle adjustment, I want to check the timing first.

Here are a couple of pictures of the shuttle...

There is an adjustment screw (#2) but I can't seem to locate it.

If it ain't broke don't fix it. Try a piece of scrap and sew some on it to get everything working correctly again. And check the distance from the needle to the end of the hook on the up stroke just a little over the width of the thread should be about right. The hook should be just north of the needle eye.

I ran some stitches on a piece of scrap and the back stitch isn't hitting in the same holes.

OK, it does looks like the timing is out of wack.. What is the make of your machine? The timing isn't that hard to fix. What ever your manual instructs you to do that is where I would go to. I have my own method and it might not be to everyones liking. It should take about 10 or 15 minutes to fix. Good luck.

This isn't needle, hook, shuttle timing. It is needle and foot, feed related. So don't fix what ain't broke. Look at what positions the feed.

It says CB4500 in the title, so I'd have to guess its a Cowboy 4500, how about calling the manufacturer? I've read he's top notch and should be easy to reach.

It appears to be hit and miss, one time it misses the holes and the next it hits them.

I tend to think that it isn't timing and as CTG states and more to do with feed.

It just started doing this when the thread got caught in the shuttle and stopped the machine from sewing.

Call Bob Kovar tomorrow. There are a couple of places that could have been affected by the thread jam, which control the backstitching. One involves removing the back cover and checking the big screw on the connecting rods towards the back. If the joining screw is loosened, the back stitches are thrown off.

Also, the positions of the alternating feet have a profound affect on the alignment of the stitches.These are adjusted in the back of the head, behind the outer foot. An Allen bolt locks the rod that changes the height of the inside foot, which also controls when that foot hits the material. If the foot hits before the needle, the work gets pushed toward you, instead of away from you. The inside foot should make contact just after the needle touches the surface.

Look carefully at the feet as you rotate the wheel towards you CCW. The inside foot should not hit the feed dog until the needle reaches it first. After the feeder moves all the way back, the outer foot should drop and the inner foot and needle should lift, pretty close to each outer. Raise the stitch lever to the top and see if the same holds true in reverse.
