hi all,

My friend and I (novices who have been learning for the last few months) have been intrigued by this serger business, so we got something on ebay - a singer 14SH644, for like $50. It's a basic machine, but we really just want to learn what it's all about. The machine seems to be in working order (I know, since we have no idea what we're doing, it's hard to make that judgement) - but it turns on, we cleaned out the lint, oiled it, when you turn the hand wheel it goes through the motions fine (also the foot controller works).
We threaded it as per the manual (which thankfully came with). It had a needle only in the right side, so we went ahead and set tensions for a middle weight fabric as suggested in the manual for this case, and got out some scraps from a sewing class project. The material is a woven bottom weight and a little bit stretchy, which I thought was the strength of a serger?
Anyway... not only did the thing jam up immediately, we actually managed to bend the needle, which is amazing (hope i loaded the picture right).

We are a bit stunned by our incompetence, and were hoping someone would have a suggestion about how to go at this problem better, or what might have happened? Could the knives be the problem?

Holy moly! That needle did its job--it didn't break.

I have a Singer serger, although not the model you do and I've experienced this same problem. There could be several things:
1) you were tugging too tightly on the fabric
2) the needle wasn't inserted all the way up (keep in mind when you insert two needles, they aren't the same length--just for reference-- as your post said you didn't insert two)
3) your knife might be disengaged/lowered. My machine likes to have the knife engaged, and when I'm working with fabric, I'll barely touch the edge of the knife. For some reason, the machine is happier this way.
4) the needle could have been slightly bent to begin with
5) the needle thread could have gotten stuck on the spool or somewhere in the thread path

I use to serge while standing up until realized that I was moving my fabric over too far away from the knife, and the fabric jammed and bent my needle; just like yours. Now that I sit when serging, it seems I don't have this problem.

Also, move your handwheel (large wheel on right side of machine) to see if the loopers are clicking. If they are, you'll need to have the machine adjusted. I check this every time I break a needle.

Wow, I thought I had created a new problem of my very own ;).

Thanks for the advice. I'll probably get back on the machine later today or tomorrow to check it out.

A couple tips:

Always make sure the lower looper thread is in front of and over top of the upper looper thread--very important!

After threading, pull both looper threads towards the back of the serger--not under the presser foot at all. Pull needle threads off to the left--sort of under the rear of the presser foot. When you start to serge, it works best to have needle(s) threads and looper threads separated.

Anytime you rethread, always serge a thread tail to test stitches before putting fabric under the presser foot. You can even hold those thread tails when starting your test as that will make sure the beginning stitches are not bunching up on the stitch finger under the presser foot.

Serging is great fun! Hope you get it going!
