Q:

I have a Kenmore 38512714090, 20-year-old mechanical sewing machine and I'm having trouble with the tension.

A:

Thank you for your question on the tension adjustment.

You would need a special measuring tool to be able to set the tension as described in the manual.

I do not use one to these adjustment tools but you should not need one either.

Please set the bobbin tension and the point where by holding the thread the bobbin will drop an inch or so when you do a yo yo motion with the bobbin assembly. This may it easier to adjust the upper tension assembly.

If you thread the top tension as shown in the picture below and then do the tug pull on the thread with the presser foot down you should be able to get it correct after a number of tries.

It is a feel that you get for this as a sewing machine technician.

Please keep trying and I will give you the image just incase you do not already have it.

If you cannot get it adjusted correctly you may have to replace the upper tension assembly, but I a confident that you will get it resolved.

Upper tension assembly for model 385.12714090 .

Please let me know how it goes and if you need more help please reply, and Happy Quilting.

Thank you Andrea for the update and no you can't yo yo you machine for the top tension. Since you did some adjusting on the main adjustment screw and not just on the numbered dial I would suggest that you set the numbered dial to 3 and then adjust the bottom bobbin tension and then let the presser foot down to close the upper tension discs and then see if you can feel the same tension on the upper tension thread as you did on the bottom tension thread. You may also want to take some waxed dental floss and run it back and forth through the upper tension discs with the presser foot down to clean any lint out of the discs and lubricate the thread path with the wax off the dental floss. It is a little hard to tell you exactly how the tension should feel but you goal is to match the upper and lower tension for a stitch that will lock in the center of the material. I like to use the widest zig zag because it will make it easier to see which thread is dominant, so you can adjust the upper tension dial higher or lower to balance the two threads. I do not know of your quilting experience but if you are going to top stitch the quilt yourself I would suggest using a 1/4 seam allowance foot for piecing and a walking foot for top stitching. Please let me know how it turns out. And if you have anymore questions please feel free to ask. P.S. that fan quilt took six months to complete, and it was a gift to a granddaughter. Sam A.

Thank you for the update and I am glad that you got your machine working well enough to finish your first quilt. I am sure your little girl will cherish this quilt for a long time. Because it is you first quilt I would suggest that you top quilt on the seams, what is called stitch in the ditch. My youngest daughter still has the first one my wife made for her when she was a child. We really enjoy making these quilts together. You may want to be careful though because it can get addictive once you start quilting. My wife say's that it is a race to see who will have the most fabric. Thank you again for your update on your machine and quilting project. Sam A. Happy Quilting.

Yes it can be a fun hobby. My wife did top stitch quilting most of yesterday. You may want to consider ready made embroidery pieces that you can sew onto the top of the quilt. But your idea of having someone with a machine that has electronic embroidery templates that either built in or can be downloaded from a computer. I am sure she will cherish it for a long time. When you go to the fabric store the next time you may want to ask if there are any local quilter’s guilds in your area. I sure there are. Please let me know your progress as you continue to quilt. Happy Quilting. And please post a picture of your finished quilt if you can. Sam A.
