How do you attach cutting wheel to the bit?

How do you attach the cutting wheel to a bit. I assume I need to use the pointed threaded bit but I can't get the wheel to thread on the bit. The bit appears to big for the wheel.

You need a # 402 bit. This comes with a screw on top that detaches and goes through the hole in the cutting wheel (very small hole). Then just re-attach it to the bit and you're in business. Depending on the particular cut-off wheel you're using, the wheel can be extremely fragile. Even though it will cut steel, it is brittle. ALWAYS wear safety glasses when using a cut-off wheel particularly, they will inevitably shatter and go flying!
Probably best to go to a local hobby store, buy a few bits for $10, and pick the owners brain about the tool.

Do not use the threaded bit. You need a mandrel that has a tiny screw on the top. Take the screw out and thread it onto the cutting wheel and then screw it back on. My book says its mandrel #401.

How do you remove thread caught in hand wheel in babylock?

Take a good look in your manual and see how to clean and oil you machine. Now, take a new paint 2" brush(from Dollar store) and really brush that thread, when you get a little tail slowly pull it while turning the handwheel slowly is the key. Use tweezers if you need too. Keep going until you have no more thread, remove bobbin and cut the thread attached to the machine.

Hi. I have a new overlocker. Fabric got jammed ,got it out but machine now jams at half turn . Could some fabric still be under feed dogs ? How to get it out ?

Hello Jenny hornsey

This may sound traumatic, but there is no easy way to pin point where the tie-up is located. So proceed as follows.
Cut all the threads as they come off the antennas.

Open the front cover and pull-out all the threads by pulling them straight toward the back. If they do not come easily, try moving the hand wheel back and forth by a 1/4 revolution .. this is like a rocking motion. If still not budging, start cutting back the threads and removing them in sections until all the threads are cleared. If this step is still challenging; check that there is no residual fabric or threads still wrapped around the loopers or other part/s of the serger. If so cut them out bit by bit until everything below is cleared.

Great. Now check for threads wrapped and/or jammed anywhere above.

Since the overlocker jammed, it is possible that the needles were bent. This will continue to cause issues in stitch formation. So just to make sure; change the needle/s. Make sure that the correct needle type is being used. Every overlocker is engineered to be used with a specific needle type. The needle type will be specified in the manual and will also appear on the needle package. If the needle types are not the same, do not use those needles.

Re-thread the overlocker and stitch test on a piece of fabric before pressing down on the foot control.

This should get the overlocker back on track and you back to overlocking.

Please let me know how this works out for you.

Happy overlocking

Fix a mess - the thread wound under the bobbin spindle?

so take of the thread and cut it off the needle and remove as much thread as you can see. pull through anything from the spool. take off the tray in front of the foot, there is a door right under the foot where the bobbin goes, open the door under the foot is a silver dome looking thing with a flat lever on the front, pull on this lever a little and it unlocks the bobbin holder, this whole dome piece will slide out and the bobbin is in it there is probably a bunch of thread around there, cut it out and pull out with tweezers , careful there is a very sharp hook that rotates and catches the thread, it Will cut you. you might have to yank and cut a little while you pull . once you have the bobbin out yur at the spindle. Crank the wheel on the outside top on the right trying to rotate the sewing machine, it should move a little and by finding a thread in there you can pull it out . you can turn hard enough to make it tear the thread you wont break the machine.
Note: to release the sewing machine motor from the mechanism, you rotate the little wheel in the larger wheel, make sure this is engaged all the way, at a halfway point it acts like a brake.this mechanism is usually used when rewinding the bobbin, so the machine stops turning.

All of a sudden , as soon as i finish sewing a piece of fabric the thread will break. i can continue to sew as the main machine is still threaded.

There may be a bit of thread stuck in the bobbin or somewhere under the machine. Turn the machine sideways and look with a flashlight. Then turn the wheel a couple times and look again...Good Luck...xo

How can I free up the thread take up lever whcih is seized in my brother bc2100 sewing machine?

Cut the jammed thread away, carefully. It may only need the thread path cleaned of all loose thread bits after you cut off what's gotten jammed up on the lever.

My bobbin seems to be incorrectly, after a struggle -now the needle keeps losing its thread, so I'm sowing with no top thread!!! What am I doing!!'

Assuming your bobbin is threaded correctly. Try to pull your top thread thru the needle a bit longer & suggest you turn your hand wheel towards you till the needle just poked thru the fabric, then only you start sewing.

Artista 180 - I keep getting error message to check upper thread - happens almost every stich - changed thread, changed fabric, changed needle - error keeps happening...any ideas?

There are a number of possible reasons for this, but, assuming the thread hasn't actually broken (!), it may well be that the upper thread sensor flag has come off the check spring - this is something I see fairly regularly and is frequently the result of people pulling the upper thread 'backwards' out of the machine a bit too quickly, rather than cutting it off at the spool and drawing it through the machine in the correct direction. It's a bit fiddly and very difficult to explain how to check this, without taking all the covers off. However .... if you take the head cover off (single screw) and look carefully at the bottom of the metal takeup lever cover you will see a large slotted screw with a spring wound around it - this is the check spring. The end of the check spring pokes-out behind the takeup lever cover and the thread goes through a loop in its end when you thread the machine up. Thread the machine up as far as the takeup lever, take hold of both ends of the thread and gently raise it - you should see the check spring move upwards. Now, look very carefully at the part of the spring between the big coil around the screw and the loop where the thread passes-through ... there should be a black plastic part attached from the other side of the takeup mechanism (you cant get at this without taking the front cover off !). If it's not attached, you can very very carefully wiggle the spring and sensor flag back so that the spring sits in the slotted part of the sensor flag (either that or take it to your Bernina service agent !). If the sensor appears to be attached, it could also be the optical sensor which is attached to the front cover just above the reverse switch - sometimes this gets full of fluff or I have seen a couple with manufacturing faults where the sensor flag gets caught in the optical sensor circuit board ... whatever the case, this is really a job for the service agent.
Good Luck

I have an Elna 745 serger/overlock machine. Whenever I'm doing a double cover stitch hem, when I'm at the end, the thread release lever does not release the thread. To release it, I have to cut the...

There are two methods to release the cover stitch with sufficient slack in the thread. Since you are using the thread release lever, did you set the Brown tension dial to zero? Before changing the tension, you have to first lower the needles to their lowest position in the fabric with the hand wheel and then turn the hand wheel backwards to bring the needles to the highest point in the cycle.

The other method may work better for you. Bring the needles to the highest point in the cycle and lift the presser foot. Then slide a thin object (a sewing ruler, for example) between the presser foot and the feed dogs and pull the needle thread towards you. Cut the needle threads Then pull the fabric away from you before cutting the looper threads.

Both of these options are described on page 98 of the manual, which is available from Elna. The current link to the manual is . Pictures for the second method are available here: . (Ending the double cover stitch hem is the same as that for the single cover stitch.)

I hope this helps.

White serger

You did not say it jammed from thread or just stopped working.

If it is thread, then you will need to carefully use embroidery scissors with a sharp point or a razor blade to cut at the lump of threads and carefully pull them out with your tweezers till you clear the mess. Use your vacuum to get all bits out of there, being careful and not hitting the loopers. You can knock them out of alignment with thread jams and such.

If it just stopped and you cannot turn the wheel, then it needs a trip to the repair shop, either your dealer or to a sew and vac repair where they know how to service sergers.
