Why does my simplicity sewing machine keep jamming and the needle keeps breaking

My Grammy gave me her old Simplicity sewing machine and every time I go to use it the Bobbin keeps Jamming and the Needle breaks! Am I doing something wrong? Do I need to get it looked at? If so how much will that be? Thanks so much! J.L Cross.

It probably needs a good cleaning, proper threading and the correct seam starting technique.

Here are some common problems beginners who don't thread their sewing machines properly are likely to see:

Sewing machines should be threaded with the thread takeup lever and needle at the highest position of travel, with the presser foot UP. Follow the threading diagram in your sewing machine manual. Make sure you've got the correct bobbin in the bobbin case (two of the most popular bobbins look so much alike it's not funny) and it's in the correct orientation.

When you're ready to start a seam, do it like this:

  1. With the top and bobbin threaded, and about 3" of "thread tail" pulled out from the needle and bobbin case, pull the thread tails under and behind the presser foot.
  2. Place the seam under the needle.
  3. Using the handwheel or the needle up/down button, drop the needle into the fabric at the start of a seam (note: handwheels should always be turned in the direction that causes the feed dogs to move fabric from the front of the machine to the back).
  4. Drop the presser foot.
  5. Holding the thread tails behind the presser foot, take 2-3 stitches
  6. Drop the thread tails and sew normally.

Not all machines require holding the thread tails, but enough do that you might as well make it a habit. Saves many bad words and thread tangles.

If this machine hasn't been professionally serviced in the last couple of years, it's probably time to take it in. Can't tell you what it would cost where you are, but a typical COA (clean/oil/adjust) runs $50-100 in my part of the world, and when you get the machine back, it should run like new. Here's the sort of thing that happens at the shop:

The three most common causes of needles breaking that I see are:

1) Pushing or pulling the fabric under the needle. Guide the fabric, don't haul on it. Let the feed dogs do the work of transport. 2) Sewing onto or off of a thick area, like the thick spot on the side seam when you're hemming jeans. Use a "hump jumper" or a fold of fabric to keep the presser foot level while you're making the transition between the two thicknesses. 3) Sewing machine starts to jam (usually a threading and seam starting fault) and you keep stitching till the needle bends and breaks.

Remember to match the size of the needle to the thickness of fabric being sewn (in general, you want the smallest needle size that will let the stitch form) and make sure it's right way around in the machine and fully up in the needle clamp. Otherwise you'll get "skipped stitches": _ _______ _ __ _ ___ _ instead of _ _ _ _ _ _ _ _

If you don't have the manual, try to get a copy. It's one of your best sewing tools.

Amen to that! It's funny how many people are given a perfectly good old machine, and think it should run right off the bat with no maintenance. Unless the donor was scrupulous about cleaning and oiling it almost certainly needs a good servicing. You wouldn't take off on a long trip with a new-to-you-used car without, at a minimum, checking the fluids.

I would add to all of Kay's good advice, make sure the needle is inserted in the *correct* way. A needle in backwards will cause problems. and it goes without saying (but I'll say it anyway), be sure you have the correct needle *for your machine*, in the proper size for the project.
