Question about Toyota STF39 Mechanical Sewing Machine

Open Question

Cannot get the tension right and think there is a problem with the stitch selection dial.

I have gone through the manual and done everything step by step to get the correct tension, but it is still sewing incorrectly. On the stitch selection dial and with the settings as recommended in the manual the only way to get it somewhat straight stitching is to have the stitch width dial at 0 (which is not what the manual recommends). If you want to stitch in a zigzag you have to increase the stitch width dial, but the manual does not address that. This still does not solve the tension problem though.

SOURCE: bobbin tension?

Try threading the machine with the presser foot up to see if this will solve the problem.

When a sewing machine is threaded with the presser foot down, the thread cannot properly enter the tension. No tension control of the top thread and it cannot form a satisfactory stitch.

You might be able to find a manual for your machine at sewusa.com

I think you need to use a teflon foot (the white plastic one) when sewing vinyl. Hope this helps.

SOURCE: I have a mORSE 6500

The tension will depend on the material (knit, heavy denim, etc). See this pdf for a description of testing and setting the tension: www.ca.uky.edu/HES/fcs/FACTSHTS/CT-MMB-213.pdf . Most of my sewing is on double knit fabric and I start with the tension on 4. (Turn the knob to the right to get a higher value and tighter tension). The stitch length depends on the material if you are basting (for test fitting or prior to installing a zipper, for example) or if you are sewing the seam. Basting uses a long stitch, about 5-6 mm (4-5 stitches per inch). Most seams for a mid-weight fabric use a stitch length of 3-3.5 mm (8-9 stitches per inch). See Table 1 here: http://www.dummies.com/how-to/content/making-machine-stitches-work-for-you.html for more details.

To insert the cams, open the top of the machine and identify the fixed cams in the machine. If another specialty cam is installed, you may need to remove it to put in another cam. My machine (a Singer) only has space for one specialty cam at a time. The cams are labeled with the stitch that they provide and the stitch indicator faces up on the cam stack. (For my machine that means that the tall ring of the cam is up.)

A You-tube video of using the Morse 6500 is available: http://www.youtube.com/watch?v=ksfZZyqO1eE .

I hope this helps.

Bottom thread seems too tight!!! Help!!!


If the bottom thread is tight there should also be loops on top and this means that the upper tension is too tight.
Get out your manual (http://www.singerco.com/uploads/download/1198_8763-efs.pdf) and turn to page 24. Under "ADJUSTING TOP THREAD TENSION" it tells you that if you're having thread tension issues, change the tension control dial on the top of your machine from auto. It also shows you a diagram with your problem illustrated on the right side of the page. The bobbin tension is set at the factory, so all tension problems can be solved with top tension adjustment. Set it manually and if it loops on top, loosen the tension a little. Test again. Repeat until loops are gone.
Using different colours on top and bobbin and a contrasting fabric (e.g. black top, white bottom, light blue fabric) means you can easily see what's happening. A perfect stitch is when you see exactly the same stitch pattern on both sides of the fabric. On top, the bobbin thread colour appears between stitches as a tiny dot and on the bottom, you see the top thread dot between stitches.
If it's impossible to get the tension right, take it to a technician, because it's a sign that the hook timing needs attention.

Singer xl-400 bobbin tread to loose when momograming


It means that your top thread tension is tighter than your bottom thread, and it's pulling your bobbin thread up. You loosen your top thread by turning the dial towards the "S." You should only have to loosen it by a maximum of one number; if it's more than that, you may have to adjust the bobbin thread tension.

You do that by first turning off the machine and removing the embroidery unit. Turn the tension dial to S. It helps to use a different color top and bottom thread, with the scrap fabric a third color. Run a straight stitch and zigzag stitch and examine them. If one size of the zigzag looks like "chicken tracks" or one side of the straight stitch is a straight line, it means that side is too tight. Take a look at your user's manual on page 11. If your top tension is on "S" and it is the side that is too tight, you will need to tighten the bobbin tension, to match the top tension. Tensions are a BALANCE.

The next step needs to be done systematically and carefully. If you don't, you can really make things worse. Set your mind to doing everything step by step--don't get tempted to jump ahead. Take the needle plate off and take out the bobbin case, and locate two screws on the side. One is a Phillips screw--leave it alone. The other is a straight screw--that's the one, and you will need a tiny screwdriver to adjust it.

The rule is "righty-tighty, lefty-loosey." Remember, you are trying to match the top tension! Give the screw on the case no more than 1/4 turn, reinsert and retest. You should see at least a little improvement. Keep doing that until you have balanced your stitches, and DON'T jump ahead! The difference between too tight or too lose is often a very small turn of that screw--especially when you're close.

Model # 64 60 viking sewing machine looking for manual for sewing leather or canvas which cam to use in it


As to your question about leather, the 6460 has a special stitch for sewing leather. Select Colormatic cam C and install in the cam hole at the back of the machine. To remove/add a cam turn the upper left hand dial on the front of the machine to the small dot. This disengages the cam. Gently remove the cam by pulling straight out from the back of the machine. Install cam C straight in, ever so slightly twisting it back and forth into the hole to find the sweet spot. You'll hear a click when it's all the way in.

To use Viking's leather stitch, turn the upper left dial to the color yellow. (Note: The slash line on the upper left dial is a stop. You can't turn past that point. Go in the other direction to get to the icon or color you want.) Turn the upper right and bottom right dial to yellow also. The upper left dial is what selects the particular stitch on the cam, the leather stitch in this case. The upper right dial selects stitch length, and the lower right dial selects stitch width. You can move the right dials within the color range. Experiment on a scrap of cloth to get the stitch size the way you want it. The leather stitch looks like a straight stitch with a block style edging to the right of the straight stitch. This is supposed to give a stronger stitch to the leather rather than a straight stitch by itself.
If you don't have the manual for your machine: Select which of the eight cams you want to use. All the cams are removed/installed by turning the upper left dial on machine front to the small dot. At the rear of the machine, pull/insert cam straight in or out and twist slightly as you push in or remove to find the sweet spot. Move the dial away from the small dot to lock the cam in.
Turn upper left dial to stitch type you want and match the other dials to that same color. Upper right controls stitch length, lower right controls width. Bobbin tension is controlled by the dial at front left of the machine, above the needle.
Cams A-C are the workhorse cams and the rest are embroidery stitches.Straight stitch, button and stitched zig-zag will work on any cam. These stitches do not rely on matching a color code. To use those three: To select straight stitch, on the upper left dial, choose the icon that looks like a buttonhole with a zig that trails off to the right. Select stitch length on upper right dial and turn the lower right dial to zero, going by number rather than color.
To select stitched zig zag, turn upper left dial to the broken zig zag icon (to the right of the straight stitch icon). Select stitch length and width.
To move the needle to the side for buttonhole stitching or other times when you want the needle off center, turn the upper left dial to the button icon. If stitching a button hole, set stitch length to zero and lower right dial to desired stitch width. Push in the small white button that's beneath the lower right dial in order to prevent the feed dogs from moving the fabric forward. Pushing that button in is also handy for putting cloth under the foot before sewing as it prevents snagging and is used for tacking.

I need to learn how to make a buttonhole on my Husqvarna 210 electronic sewing machine.My manual is gone.


You may be able to still get that manual, check with your dealer. If not you can call Viking at: 1-800-474-6437 if it's out of print for a photo copy of the original owners manual.

To make a buttonhole do the following:

1. Turn the selector dial to the top position, That is the first step of the buttonhole.
2. Turn the stitch length dial (the bottom dial) to the picture of the buttonhole, it's between the 0 and the 1 on the dial.
3 Put on the "C" foot and put the tension dial, (the small dial just above and to the right of the needle) on 4.
4. On a test fabric, sew about an inch or so and stop. Turn the selector dial down one click and sew the bar tack of the buttonhole. Just do a few passes, don't build up alot of stitches here.
5. Turn the dial down another click to the 3rd step, the right side of the buttonhole and sew until you reach the place where you started the left column of the buttonhole and stop.
6. Turn the dial UPWARD one click to the bar tack position again and do another bar tack like you did at the top of the buttonhole. Don't build up alot of stitches here, about three passes does the trick.
7 Remove the fabric from the machine and when you cut the threads, leave a tail about 2 inches or so of the thread. From the back side of the buttonhole, pull gently on the thread and a loop from the front thread will appear on the backside. Pull the front thread to the rear and tie off the threads and then cut them close to the knot you tied and the buttonhole will not come apart.

What are the settings for regular sewing, I do not have a manual. It has 3 knobs on the front and 1 on top? This might have something to do with my problems.


The three front dials are as follows....left to right-Stitch width, type of stitch, and stitch length. The dial on the top adjust the top tension.

For straight stitch you want 0 stitch width, straight stitch, 3 for stitch length.

For zig zag you want turn your stitch width to how wide you want the zig zag, choose zig zag stitch, and choose how close you want the stitches to be on the stitch length dial. Practice on a piece of fabric. Usually for zig zag you will want to loosen your top tension a little bit.

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing direction...do not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the needle...do it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.

Tension issues


I'm working on 2 different singers. One, Singer 3343C has upper and lower tension problems that turning the dial just doesn't help. How do I adjust the tension on this drop-in bobbin carrier? My other machine is Singer Model 15 (AL311850), I'm having upper tension problems and the machine is sewing loudly-it's never done that before. Help!
