Feed Dogs, Thread Tangle

I have a Singer portable, mfgd in 1941 (Model AG008912).  After trying to sew over a very heavy seam, feed dogs started bumping against the chrome plate beneath the presser foot. (The plate the needle goes thru.)

Also, when trying to catch bobbin thread, the thread from the needle wraps around the bobbin housing (??-not the bobbin case, but the stationary housing the bobbin case snaps into.)  When the plate is removed, the feed dog moves freely, but the thread still tangles, as described.

I tried replacing the needle, removing the feed dog (couldn't), switching the direction of the threaded bobbin, cleaning & oiling moving parts.

Great if you could tell me how to fix this!  The little machine is a gem.

Thanks, Jeanette

Re: Feed Dogs, Thread Tangle

Hi Jeanette! You have a Singer Featherweight--the best sewing machine ever made! (Mine dates from 1950/51 and I wouldn't trade it for the world.) These beautiful, sturdy machines were designed to be easily repairable at home, but you'll need a copy of the Service Manual (get the Instruction manual too, if you don't have one.) Go to and check out what they have available.

I had a similar problem (needle thread not catching the bobbin thread) and the problem was that I hadn't put the needle in correctly (flat side to the left). Also, I will occasionally get thread wrapped around the bobbin housing--sewing along just great and then everything comes to a screeching halt. I'm not sure why that happens, but I'm getting pretty good at taking the bobbin housing apart. The manual is pretty clear on how to do it. You can contact me direct at for more information.

Buttonhole attachment inplace ..all settings as directed.foot down..machine will not feed material and produce buttonhole

Are your feed dogs up or have they been accidently lowered? Are the feed dogs blocked with thread? Clean them out with a toothpick if so.

When i start to sew on my Janome sewing machine model Sewist 525S it does a couple of stitches on any stitch type then bangs then sews then bangs then stops. I look to see the problem and the bobbin and...

There has to be a problem in your threading or your needle. You may have the needle inserted backwards, flat side has to face rear or the needle is bent. Totally unthread your machine and make sure that there are no tangles and that it feeding the right way. Watch how they show your for threading and winding the bobbin, plus threading the bobbin. Good luck, but I truly think it is in your threading.

I have a Singer Stylist 513 & I cannot get the feed dogs raised.

The model 513 Singer has two gears which operate the feeding mechanism. If one of these gears is broken, the machine will run except the feed dogs will not move. This is a very common problem with this model.

Thread bunchingup on bottom of material on singer

Here are some solutions to try.

* Re-thread your machine
It may be threaded incorrectly.

* Raise your feed dogs If your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

I hope this helps.

Why would my Singer 6235 not feed the fabic:

h! there,
fabric moves forward when machine run due to movement of feed dogs,feed dog has a teeth, when your foot presser goes down attached to fabrics the pressure hold the fabric between pressure foot and feed dogs that why when machine run feed dogs pushed fabric when recieved stitch.try to check adjustment of feed dogs it maybe set at rest or neutral.reset it to upward towards needle.check also bobbins thread if accumulation was build up under feed dogs.regard and have a nice day.

Singer model ce100 does not sew with pedal

Check your feed dogs. On the front, left at the bottom is a manaul switch. If you push it to the right it drops the feed dogs, for embroidery and when you push it left it lift the feed dogs. Just remember to turn the handwheel towards you after switching it to the left, until you hear a clicking sound and the feed dogs engage. Hope this solves your problem.
