Bobbin Free Sewing Machine
Posted in Crafts on 12/05/2010 03:39 pm by admin
Can you help me with my Kenmore sewing machine?
I have this sewing machine: http://www.sears.com/shc/s/p_10153_12605_02019233000P?mv=cf&vName=For+the+Home&cName=Sewing+Machines+%26+Accessories&sbf=Brand&sbv=Kenmore
the thread from the bobbin on the finished result on things that i sew look a lot different than the thread on the top. i’ve tried every tension number, but it’s only the top that seems to change. what else is there to change? it’s really loose and ugly. if i don’t sew a straight line, it makes it realllly obvious because it’s so loose. how can i fix this besides having a repairman come in? i don’t think it’s for free? i got it from sears.
my needle is already tight, i just cleaned the lint from under there, it is threaded right..
Are the loops on the top of the fabric when you sew? If so, you’ve got the bobbin misthreaded in the bobbin case, junk under the tension spring, missing bobbin case tension screw, or similar.
Make sure your bobbin is correct… there’s not a lot of visual difference between a type 15 and type 66 bobbin, the two most common generic bobbins. If you have multiple machines or you’ve bought the wrong kind of bobbins, it’s easy to mess up there.
If the loops are on the bottom of the fabric, the usual cause is a misthreaded upper machine tension — generally caused by not threading the upper tension with the presser foot up. Raising the presser foot opens the tension disks and allows the thread to actually enter the tension.
Normal upper tension setting is 4… if you’ve cleaned the tension, threaded properly, and you’ve got dressmaker weight thread on both top and bobbin, and you have to go below 2 or above 6 to get a balanced straight stitch, your machine is probably due for a professional COA (clean-oil-adjust).
But try the 10 minute fix first…
These are the likely culprits:
–Bad needle
–Dirty
–Misthreaded
–Seams started incorrectly
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).
– 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.
If this doesn’t fix your problems, you may have some thread
caught farther in the machine than you can spot… doesn’t take
much for some machines to start pitching a fit. Or you may have
accidentally knocked the machine out of time with one of the
jams. Bad timing is actually a fairly rare event, often preceeded
by broken needles and loud noises, but a good solid jam is
another way to throw off the timing. You can check here to see if
you think timing is the problem:

but that’s generally something that a repair shop needs to
adjust.
