I can't seem to find this manual online.  The SM is a 15 clone, but the tensioner has differently shaped parts and I can't get it together properly. TIA

Margaret,
I don't have a manual or this machine. Have you gotten it figured out? I know it seems strange, but it seems like I have a clone that has a tension similar to the one on page 17 of this pdf -> http://parts.singerco.com/IPinstManuals/15-91.pdf maybe it will help. Do you have a picture of it before you took it apart? and/or the pieces?
Janey

Hi, Janey and John! I'm going to send you a lot of pictures now - hope they show what's going on.  I wonder if I'm missing a piece, or have the parts aligned improperly, or have the wrong spring. Sew Classic only had two choices for springs for a 15 clone, so I ordered both of them and used the one that is the same coil length as the original.

IMG_1088.JPG  IMG_1089.JPG This is how I had it set up, with the new take-up spring (BTW, it didn't work right with the old spring either.)

IMG_1090.JPG  IMG_1091.JPG These are pics of the old spring and what my stitches look like, no matter where the tension is set.

matter where the tension is set IMG_1092.JPG This is the position these parts were in when assembled. IMG_1093.JPG  IMG_1095.JPG Further pics. IMG_1096.JPG  This shows the big spring - looks like it should be straighter than that!
IMG_1097[204].jpg  This one is sideways, but shows all the parts in the order in which I removed them.

I have never had to take apart and reassemble a tension before, so it's quite likely I did it wrong.  I thank you so much for being willing to help me!

Margaret

Fear Not, Margaret.
We well get you through this.

Here is a .pdf that you may find helpful. It illustrates several types of common tensioners.

Hope this helps.

Thank you SD for reminding us about this resource.

Margaret,
I agree the spring doesn't look quite right. IIRC, the spring end (the smaller circle) might need to be through the split in the tension stud. It looks like you have it inserted correctly with the larger end toward the machine. I know not all springs are alike. Does it feel like it is tightening or loosening as you turn the outermost part?

I think that it should be threaded so that the thread goes back almost straight up over the bar and then through the check spring then up to the take-up lever. The best drawing I could find is on page 14 of this pdf -> http://www.singerco.com/uploads/download/55dc9c90390ea8ad32a3a1c51afbce7d9fb8c05e.pdf

Thank you, Steve! I lost this document when the original site made it unavailable. I will save it. What do you think about the beehive spring? Is it ok like that?

I may not have time to work on this for a few days, but will get back to you!

Margaret you've got it threaded wrong. I think Janey has it right.

Yes, it looks like the threading is wrong. I will try to get it right tomorrow. There's lots of good info on how to line everything up properly, too. Planning a drive to Hermiston, OR, tomorrow to look at the Handiquilter line, so may not get much repair work done! Thank you all.

Ok, got it back together and threaded it correctly and it's stitching. I can't get the tension right, but I'm pretty sure that is because of the bent up beehive spring - putting differential pressure on the tension plates. I will steal a spring from another machine to see if it comes out better, but not until tomorrow.

The other potential problem is that I might be missing a part - the diagram for the Singer 15 calls for a small stop washer between the beehive spring ang the tension dial. I don't know if I need that, this being a clone and a different kind of assembly. Do all the clones you've seen need this washer? Thanks for all your help!

That little washer may be hard to get! They don't offer it on Sew Classic. I need a parts machine!

Would you like a 15 nose plate with a tension?

Miriam, that would be the perfect solution. This machine is for sewing, not for looks or authenticity. PM me with the price!

Friends, I am absolutely done with this machine.  I've wasted enough time on it! I borrowed a 15 faceplate with a tension that I know is working right, and it still didn't work.  I believe someone must've replaced the original face plate, because I couldn't screw in the thumb screw and also put the plate in the right position. The hole on the machine that takes the thumbscrew is up too high.  I suppose you could use a Dremel to make the face plate hole a bit longer at the top, but I'm not going to do it.  This machine cost me $30 and way too much time. I will happily sell it to anyone who will pay me $30 plus shipping.

It's actually a nice looking machine, but has very little it any wear on the decals.  I suspect it hasn't worked right for a very long time! I was also unable to get the stop-motion washer on the handwheel to work properly.  It has a case.

ba 5.jpg  No other accessories, though.  I could probably sell the parts for more than I paid for the machine!

Tried it, Miriam. That's not the problem, it seems. I'm putting it away until I can get over to see Cari. Heads up, Cari!

yes, bring it with you and we'll see if we can get it going. I have at least one clone face plate we can try on it.

Ok, great. I will be there when the snow ends, maybe July. I'll bring my other two clones if I can find them!
