Tip & How-To about Sewing Machines

3 things to do if your sewing machine stops sewing right

1) re-thread your machine
2) check your upper tension and stitch length to see that nothing got changed
3) change the needle

not necessarily in that order, but try these things first before taking things apart.

Brother 1034d serger skipping stitches. Stitches are loose even when adjusting the tension.

It appears that there are two issues: skipping stitches, and, loose stitches. Let's deal with them individually but first some general points to check.
1. Change both needles for completely fresh ones out of the package. Make sure that they are inserted all the way up, this is very important. The right needle should appear longer than the left one. Make sure also that you are using the correct needles for your serger.
2. Use a good quality thread with very little stretch, almost no fuzzies, and in pastel colour. Dark thread ages quicker, therefore has a shorter shelf live. A good quality sewing machine thread is also acceptable.
3. Make sure that the tension dials are clean and free of lint or other debris.
4. Re-thread the serger in this order, keeping the presser foot in the down position at all times
a) Upper looper. Ensure that the thread is securely embedded inside the tension discs. Place the thread tail under the presser foot to 11:00 o'clock and place the presser foot down again
b) Lower looper. This is the difficult one to thread but make sure that all the thread guides are properly threaded as well as the upper looper elbow. Check that the thread is lodged between the tension discs. Once the lower looper eye is threaded, place the thread in front and over the upper looper and then under the presser foot to 11:00 o'clock and place the presser foot down again.
c) Right Needle. Thread the right needle path, again ensuring that the thread is between the tension discs. Place the thread tail under the presser foot to 11:00 o'clock and lower the presser foot.
d) Left Needle. Proceed as with left needle.
e) Double check that all tension dials have their respective threads embedded between the discs by pulling firmly up on each thread above the tension dials.
f) Check that the stitch length is set to between 2.5 and 3.0, differential to normal, blade position to middle, blade is engaged, and upper looper converter not in use.
g) Set tensions to recommended setting for 4-thread overlock.
g) Make a test stitch out. How is it? Still having the same issue/s?
If yes, continue with the items listed below, otherwise have a great time serging.

Skipping Stitches:
1. Check that the looper tips are smooth. Burrs will cause problems.
2. Check that the needles match the type of fabric being sewn.

Loose Stitches:
1. Double check threading.
2. Debris caught between tension discs will also manifest itself in loose stitches. Take an 8" X 6" piece of medium weight clean and lint free cotton fabric, fold it in half length-wise and pass the fold only firmly between the tension discs from top to bottom (with the presser foot up and no thread in the tension dials).

Re-thread and test stitch. How is it now?

My stitch length is tiny and will not change

When selecting a stich, there's a button with a triangle with one edge pointing down. There you can select Needle Position and Stitch Length. --PDF manual, page 23

The thread tension has no influence on the stitch length. It just adjusts, where needle thread and bobbin thread 'meet' inside the fabric. A too high tension means, the bobbin thread is pulled trough the fabric and can be seen on the upper (needle) side. A too low tension means, the bobbin thread is not pulled through the fabric and you can see the needle thread on the bobbin side.

How do I get the stitch length to be consistent? It changes with speed

consistent stitch length depends primarily on tension settings. there are 2 different tension settings on all machines. 1. upper thread tension. 2. bobbin thread tension. since these work together to create the correct stitch length+width, having either of these adjusted inappropriately can significantly impair stitch quality. "knowing' your machine has a lot to do with knowing how tight or loose the tension should be for BOTH settings. the settings will be different for each type of stitch, for each type of needle used, and for each type of thread used, meaning tensions will need to be re-adjusted after each change. in other words, the setting for a medium-width zig-zag with a size 10 needle using mercerized cotton thread to sew light-weight canvas will be completely different than the settings for a regular straight stitch using a size 8 ball tip needle using polyester thread to sew silky lingerie material.

Stitch tension problem - bobbin thread lies flat or bunches. If you increase the needle thread tension there is no improvement - even at the highest needle thread tension the bobbin thread is a mess. Any suggestions - I have checked the bobbin thread tension also - turned the screw on the case and shook the thread and case to see if it dropped evenly. This is a Consew 7360R Industrial machine working on patio - outdoor fabrics. I have tried size 18 and 16 needles and 3 different size threads - all stitch the same.

Good day!

A sewing machine operator can often help themselves when their machine does not operate properly.
Here are some simple instructions, which if properly used can save time and mechanics service calls.
TROUBLE;UPPER THREAD KEEPS BREAKING;
This could be trouble;================Do this;
1.Top tension to tight================loosen tension 1 turn
2.Machine improperly threaded=========check threading
3.Thread twisted on guide post========"
4.Thread twisted out of tension======="
5.Take up spring bent or broken=======Check action of spring
6.Thread jumped off pull off finger===Check threading
7.Needle bent or burred===============new needle
8.Bad cone of thread==================try another cone
TROUBLE;LOWER THREAD KEEPS BREAKING;
1.Bobbin tensionspring to tight=======Loosen tension slightly
2.Bobbin threaded wrong===============check threading
3.Bobbin wound to tight or uneven=====try new bobbin
4.lint or thread on bobbin case=======clean inside case
5.Lint or thread inside hook==========clean inside hook
6.Bobbin case nicked bent or burred===check/change case
TROUBLE;MACHINE STARTED SKIPPING STITCHES;
1.Needle bent or burred===============change
2.Needle set in crooked===============Check
3.Thread jumped off take up spring====check threading
4.Thread jumped off pull off finger===check threading
TROUBLE STITCHES SHOWING LOOPS;
1.Forming loops on top of cloth=======Tighten bobbin tension
======================================or loosen top tension.
2.forming loops on bottom of cloth====Tighten top tension
3.Bobbin placed in case incorrectly===remove and replace
4.Bobbin thread slipped from under====check threading of

5.Lint or thread in top tension=======clean between tension discs


Thank you and good luck.

Instructions for threading Baby lock eclipse BLE1LX for 2 thread sergering

I have just learned this :)
Either needle thread may be engaged for 2-thread serging.
1. Open the front cover and cutting blade cover, cut the upper looper thread just above the threading guide ( this is plate that has two holes for the threads) Raise the presser foot and pull out the clipped thread from under the foot. Remove upper thread from the machine (or you can leave the cone thread on, it doesn't matter).
2. Rotate the handwheel to bring the upper looper to its lowest position.
3. Rotate the subsidiary looper up and to the left, then slip the end into the upper looper thread eye from backside.(this sounds complicated, yes? but it is very simple : the looper has a counter part that is spring-locked to move from left to right and right to left. This is the little claw-looking part of the looper that when in the postion to serg with four threads is to the right side of the looper. It looks like a scorpion's tale. If you can't figure which part it is, use your finger to probe the looper and you'll feel it give a little. This part needs to be moved to the left - it will not slide over, but swing up and over and down, like an arch. Then, where the thread comes out of the looper is where you want the little claw-like part to hook into.)
4. Close the covers. Decrease the needel tension - this depends on what the stitch length is. Stitch length: 2-3, stitch width: 3.0 = L needle n/a, R needle 1; upper looper n/a, lower looper 5
stitch length: 2-3, stitch width: 5.0 = L needle 0, R needle n/a, upper looper n/a, lower looper 3.5

Those are for a flatlock stitch - for a 2-thread rolled edge :
Stitch length: 0.5, stitch width: M = L needle n/a, R needle 4.5, upper looper n/a, lower looper 3.5
Stitch lenght: 1.0, stitch width: M = L needle n/a, R needle 4, upper lopper n/a, lower looper 3.0
