Mylock 634D looping left needle stitches

I have the above serger and the left needle stitches are looping. I have adjusted the tension and it doesn 't solve the problem. Does it with any thickness material. What else can I check on it?

    Thanks, ended up removing all threads, cleaning it up and rethreading it and so far it is working properly. Will remember your advice if it happens again.

Make sure the thread is in the tension disks. Do this by pulling the thread backwards towards the spools. Also set the tension on zero and check for any fluff, or thread that is stuck in the disks, preventing them from closing properly. Good luck

Adjusting tension on overlocker


overlockers and sergers are annoying in that every time you change materials and threads they must be re-tensioned.

Get a scrap piece of material. Thread your machine correctly according to the instructions in your manual. If no manual most sergers are threaded, upper looper, lower looper then needles from right to left. Make sure you thread with the presser foot UP.

You want to balance the stitches Begin by adjusting the looper dials, you want them to meet right at the cut edge. Then adjust your needles. Keep doing test seams until you have them balanced. If you are a novice... try threading with each thread point having it's own color. That will help you identify which thread is giving you fits.

Have fun.

Tension to loose and missing stitches


SKIPPED STITCHES ON A SERGER
1. Is the needle bent or worn--replace
2. Is the needle inserted correctly into the needle holder--check needle
3. Is the Serger threaded correctly--rethread
4. Is the presser foot pressure right for the fabric--adjust

use a scrap piece of fabric to sew on as you adjust the tension
when the tension is to loose adjust one number higher till stitch
looks good

I've just got janome 634d serger, how can i make the bottom of a T-shirt ? Thank you so much


If you want the bottom of the T to look like RTW with the double row of stitching, you cannot do this on a serger.

You can achieve the effect by using a twin needle, two spools of thread, bobbin and a straight stitch.

Make sure the double/twin needle will pass through the presser foot and opening in the needle plate below the presser foot.

Practice on a double layer of a scrap of the T shirt material as the tension may need to be slightly looser than the normal setting.
