Singer 457 Zig Zag Sewing Machine not catching bobbin thread.

Joe, you might try a larger needle than you're using. You might also want to try a larger leather needle. You machine should take needles up to a size 18.

It sounds like the needle you're using is having a problem picking up the bobbin thread, and that might solve it.

You didn't give the model name for the machine; however, if it's a Pixie or Pixie Plus, you can download the user's manual that shows you how to thread it and wind a bobbin from the Singer Sewing Machine site. The number listed above your question is not a legitimate model number; it might be a serial number.

try using a washable stablizer or interfacing.
if that doesn't help then it's possible that a gear or cam may be worn enough to cause the machine zig zag not to work properly

Hi, here is a threading diagram for you which you can also print out to save.

Happy Sewing!

Call Singer at 1-800-4singer and see if they will send you a manual, in the mean time google how to thread a sewing machine and there are some great videos available for free.

Couple of things to check is the needle new? if not change it,
Pull the bobbin thread out and bobbin case, then put the machine on a zig zag stitch, turn the hand wheel slowly and see if the hook (pointy thing that catches the thread) is just above the eye on the needle (when the swing is all the way to right) if it is not then you need to take your machine in for service.

Good luck and please rate my answer.

make sure that your needle is a good, sometimes there is a slight bend or burr and you do not notice. Replace it and make sure that the flat side of the needle faces the rear of the machine, then hold you top thread end and lower your needle and watch it hook the bobbin thread (when you put your bobbin make sure you have it in your tension slot and there is at least 6 inches) then gently pull your top thread and pull your threads to the back (have at least 6inches or else the needle can unthread.

Here is a guide for bobbin winding and threading the 457 - http://www.sewusa.com/Threading_Diagrams/Threading_Pages/Singer_Sewing_Machine_Threading/singer_457_stylist_threading_diagram.htm

More than likely you have a broken vertical shaft gear.

When you turn the handwheel you should see the sewing hook moving under the bobbin case.

If not, take it to a sewing repair person and it should cost somewhere around $100 to repair.
