Lugubrious Report post Posted December 5 It was seeing fine earlier during my project but as of now it isn’t walking properly and cutting into the leather, if I sew on a smaller test piece of leather It sews fine. I am sewing through 4 layers of chrome leather, singer 153k103 Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted December 5 Something is jamming the feed motion. It may be that the top or bottom thread is binding. It could be on top, or in the bobbin and shuttle. Remove the cover plate over the shuttle and inspect the entire area to see if there are threads wrapped around it. Pull on the bobbin thread and see if it is binding. Look to see if any thread is trapped around the spring latch that holds the bobbin in place. I've had this happen when I did some jerky starts and stops. I also have found the top thread jammed on the back side of the tension disks, instead of being inside them. Then I've had top thread twist around a thread guide and bring the proceedings to a halt. If none of the above applies, verify that the stitch length hasn't changed to almost nil. If it has shortened unexpectedly, a part inside the head may have slipped. See if the stitch length spindle affects the length as you turn it. Turning it in shortens the stitches, and vice versa. Quote Share this post Link to post Share on other sites

I believe this might be the issue. This spring isn’t moving as I turn the wheel, i also notice a knock sometimes up behind at the knuckle. I’ve tried raising the feet and pressing the button behind the machine but that didn’t do anything. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted December 5 Oil inside the head. Cover all of the crank shafts and rods that move. This might loosen it up. Lower the feet and see if it moves freely with the feet down all the way. It could be that something slipped and when you tried sewing your usual thickness, the cranks bound up. There should be an adjustment on the rear of the machine where a shaft sticks out and connects to the cranks that move the feet. This shaft would be adjustable up and down by loosening a large screw on the joining knuckle on the back. You can set the alternating height to only what you need, and which avoids a lock up.

I remember this screw on the last forum post I made about this issue almost a year ago, once I’m home I’ll take photos and turn the screw, I’m sure that’ll fix it as it did in the past. I’ll make sure to document it all so this thread can be saved for future references. Quote Share this post Link to post Share on other sites

Turning the screw on the knuckle got the walking foot to work properly again. The spring hasn’t let up, is there any way I can get the walking foot to lift more? So far this is the highest I’m able to get it Quote Share this post Link to post Share on other sites

Constabulary Report post Posted December 6 read the manual for your machine there should be a section for how to increase the height of lift for the lifting and vibrating presser foot Quote Share this post Link to post Share on other sites
