Specifically, the thread gets stuck at the part where the thread slides vertically down into the hidden disc on the side. I thought it needed some machine oil, so I bought some to put in it, but it’s still getting stuck. The thread just doesn’t slide through easily. Can anyone help? Thanks!!
I’ve used it several times in the past with no issues so I don’t think I’m threading it wrong.
Is the "hidden disk on the side" the tension disks? Are they dirty? Are you remembering to thread with them open (raise the presser foot, so the thread can actually enter the tension disk)? Are you sure you don’t have a threading problem farther up (a loop of thread caught around a spool pin under the spool, or in the notch of the thread spool?)
If you oiled the tension disks, you must get those clean again. They do not require oil, and will not function well in this state. Because you’ve oiled them, you’ll need several passes at cleaning them… use the rubbing alcohol on well washed cotton cloth strips trick several times, until the dry strips are no longer smelling of oil or have traces of it.
The 10 minute fix for most of what ails most sewing machines:
– Dig out the manual. Take all the thread out of/off of the
machine. Pull the needleplate and the bobbin case if it’s
removeable. Clean and oil per the manual’s recommendation. Use a
brush and vacuum, not compressed air (which blows lint in
farther), and real sewing machine oil, not 3-in-1 type oil (it
hardens and freezes the machine) nor WD-40 type stuff (it’s a
solvent, not a lubricant).
– Clean the tension disks. Take a fold of much-washed cotton fabric (a pillowcase hem or a bandanna is good for this) and dampen it with rubbing alcohol or unflavored vodka. Place the fold between the tension disks and "floss". Floss again with a dry fold of fabric.
– Put in a new needle of the correct point style for the fabric
you’re sewing (ballpoint for knits, sharps for wovens) and the
right size for the thickness of fabric (10/70 for shirting weight
fabrics, 12/80 for heavy shirtings or light pantsweight. 14/90
for medium to heavy pantsweight, 16/100 for very heavy fabrics.
Make sure the needle is in right way around — a needle in
backwards will skip stitches or not stitch at all.
– Rethread, with manual in hand. Make sure the presser foot is
UP when you thread the top — it opens the top tension so that
the thread actually gets in between the tension disk (loops on
the bottom, not enough tension on top).
– Fetch up the bobbin thread. You need about a 4" tail of thread
top and bottom. Run both threads under the presser foot and
behind it.
– If you’ve been playing with the top tension, set it to 4. If
you’ve been playing with the bobbin tension, let me know and
we’ll try to rebalance it, but you’re likely to have to take it
into the shop.
Now, each and every time you start to sew a seam, this is how you
do it:
1) Place the fabric under the needle, and use the handwheel to
lower the needle into the fabric (be sure to turn it the right
way… seee the manual).
2) Drop the presser foot.
3) Hold the thread tails behind the presser foot with your left
hand.
4) Take a couple of stitches
5) Drop the thread tails and sew normally.
