OK...I give. Not really but I could use a little help. I have read posts on this forum for many many hours, and I am truly grateful to all the generous contributions from many savvy individuals. I have somehow been able to get things figured out without having to start a new post but I'm afraid I'm at the point now where I just can't figure this one, so here it is, my first post. Just to give you an idea of my experience level... about a year ago, when I bought the machine, the man was showing me how to thread it, and to my amazement, he showed me the bobbin!! That blew my mind. I had no idea there were two threads on a sewing machine. You see, that was the first time I'd been withing 10 feet of one.
So you're wondering....if I didn't know anything about sewing machines, how did I wind up buying a Singer 111W156.....this board, that's how (thanks Wizcrafts)!!
Anyhow....I wanted to make a boat cover, which I have, (among other things) but I've always struggled with the thread tension. I'm the kind of person, like many on this board, that likes to do things themselves. I find that it's usually the only way you get anything right. So....I had quite a learning curve with this here Singer. We have spent some serious bonding time together.
As I mentioned, I've always struggled with the thread tension, I usually have to run more tension on the needle than I would like in order to achieve any semblance of a balanced stitch. I can't seem to get he bobbin tension light enough to allow for a balanced stitch. I can't loosen the bobbing tension spring screw any further without it coming right out. It only has a couple of threads engaged anyway and I have to run it 1 1/2 turns out. I know you should hardly ever have to mess with the bobbin tension but I have to. And it's not that tight. I pulls out with a little resistance. But the top thread....I have to have that cranked pretty tight, way tighter than I think it should be. But really, what do I know, I didn't even know it had a bobbin remember?
So, I know this starts (and rightfully so), especially with a rookie like myself. The first things you're going to question are obviously the basics like, is it threaded correctly, is the bobbin in properly, is it clean, is the needle in right, is it the right needle, did I change the needle, thread, etc, etc. The answer to all the above is yes...yes...yes. I have timed everything numerous times. The tension discs are good and functional. The bobbin basket is clean and burr free. The hook is sharp and smooth. There is no slop in the clutch dog and the shafts are in perfect time. I am using a sunbrella type canvas with left twist poly 90 thread and a #21 needle.
So...I think I have most of the basics right. My question is, why do I have to run my top thread so dog gone tight. I mean, in order to get a decent thread (without the bottom thread laying strait across) I need to have my upper thread tension knob cranked almost all the way down. It is extremely tight, to the point where the thread, although not braking, is starting become distorted and kinda "squirmy" if that makes any sense. Like its really stressed. BTW, I have adjusted my thread controller a million times and currently have the thread controller spring pretty much all the way CCW (down) in an effort to help pull the bottom thread up.
Maybe there's nothing wrong. Maybe that's the way it works. Doesn't seem right to me, but I know nothing about sewing. Seems like I should be able to run my upper thread tension with the knurled knob flush with the end of the shaft, or in a couple of turns, that feels right. My bobbin has some resistance, it's not free wheeling, but I can't go any looser without the screw coming out (lost one already).
Well there you have it...a self taught rookie in over his head. If you have any nuggets of wisdom, I'm receptive and grateful for anything you may throw my way.
Thanks
