I am dying to sew up another t-shirt but I didn’t want to risk it with my serger eating up fabric left and right. I took it in on Tuesday for new blades to a nearby sew/vac store in Encinitas. It had good reviews on Yelp. When I picked it up on Wednesday, I brought my offending fabric in to test the serger out on. The chewing problem was still there. :/
To be fair to the repair shop, when I brought my machine in, all I said to him was that I needed new blades and he said he would replace those and clean the machine. I didn’t mention the specific problem I was having as I was fairly confident that new blades and new needles would fix it.
But they didn’t fix the problem.
I took a short video of what happens when serging, in case anyone can point me in the right direction.
The problem seems to happen after the fabric passes and is cut by the blades and before it reaches the needles. The fabric juts out to the right and causes skipped stitches. It doesn’t break the thread, only skips stitches. And just for reference or proof, I checked the seams on Jack’s baseball shirt I made a couple of weeks ago using this same fabric, and there was no problem at all with the stitching. It’s even, no chewed fabric and no skipped stitches. I’m really at a loss as to why this is suddenly happening and mostly only on this fabric. I tried serging some black stable knit fabric and it wasn’t perfect, but almost. No problems at all on woven fabric. Granted the green knit fabric is fairly unstable, very stretchy with little to no recovery, so I assume it is a trickier fabric to sew/serge. But my machine could serge it fine two weeks ago and now it can’t.
I took it my machine back to the repair shop and he is going to look into it further. I hope he can fix it.
