This is another one of the false rumors that goes around from time to time, usually around the 9/11 anniversary dates or whenever there is a major attack or threat.

Alot of thread on the backside, it worked fine for 2 seams then on the 3rd yuk!!

this sounds like a cotton tension problem, on the shuttle case their is two small screws which adjust the thread tension leaving the shuttle adjust the centre screw only by a very small amount clock wise and retry that's if it's a fixed shuttle case if it is of the type that can be removed then insert the bobbin into the shuttle case and thread it into the spring tensioner now hold the tail of the cotton and the shuttle case should hang down, now give them thread a sharp pull up a couple of times and the cotton should just slip and get longer if it does this then the tension is correct if it doesn't move then slacken the centre anti clockwise until it does slip as stated above, if none of the above do not cure the problem then it's possibly due to the pick hook not being in the correct position behind the needle and as to be adjusted, but hopefully it is just a thread tension problem either with the top tension which is more likely , but please make sure you have threaded the sewing machine correctly before doing any of the above.

Happy sewing

1910 Singer Hand Crank Machine shuttle hitting

Ok... great. That helps. Here is a manual for the 128 (the more modern version of the 27/28), on PDF page 9 there is an adjustment instructions for the shuttle area. Your shuttle carrier will be slightly different (no button to help remove the shuttle) but the adjustments are the same. Don't be a afraid to "tweak" your carrier gently with a pair of pliers if needed. I found my carrier had been bent slightly a few tweaks, straightened it out and gave me better results. The parts are hard to find and expensive.

I am sewing scout badges on a uniform and when I sew there is a bunch of needle thread bunched up on the bottom (the top looks fine). And the needle thread gets all caught up around the bobbin.

Clean out the bobbin area if there are any thread tangles there.

Refer to the maintenance section of the manual - see the configuration of the bobbin case and shuttle race? The bobbin case as an extending arm and the race a notch. When inserting the bobbin case into the shuttle, turn the handwheel so the needle is at it's highest position. Then lift the lever on the back of the bobbin case and insert the cast into the shuttle, arm pointing straight up toward the bed of the sewing machine.

Now thread the machine with the presser foot up - always - and see if the tangling stops.

When you forget to lift the presser foot before threading the machine, the tension control does not open to capture the thread. Then when you begin to sew, the top thread has no tension, and the bobbin thread, which does have tension, pulls the top thread to the bottom in messy loops.

Older 830 will not zig zag stitch. leavers and gears move fine. The needle moves back and forth - left and right but it doesn't pick up thread from the bobbin on the left side so it does a strait stitch...

Firstly, make sure you have fitted a new needle and that you have cleaned/oiled the hook race. Unfortunately, if you are finding that the machine will pick-up the thread and stitch OK when the needle is one side of the stitch-plate, but not when its on the other, it suggests that the timing/synchronisation is out and will need to be professionally adjusted. You can check the timing by adjusting the needle to its right-most position, remove the bobbin case, rotate the handwheel until the needle has gone down through the stitch-plate and is just about to come up again. Stop there. Tip the machine slightly back and release the black plastic hook/shuttle retainer by pressing the metal lever on the top-left side of the bobbin door, so that the hook/shuttle retainer pops open. Drop the hook/shuttle retainer, but leave the hook in place ... be careful that it doesn't drop out and slowly rotate the handwheel until the pointed part of the hook/shuttle rotates clockwise to the place where its point is directly behind the needle. Look carefully and you should see that the point of the hook/shuttle is just above the top of the thread hole in the needle. If it's much lower or higher, the timing is out and will need to be adjusted.

I have an old white sewing machine that works wonderful. I didn't get it new,so I don't have a instruction book with it. I think I need to adjust the tension because my thread keeps breaking..?

Thread breakage is not caused by tensions. If it is an oscillating shuttle machine ONLY, (do not do this on a rotary shuttle), check your shuttle tip for damage, if there is even the smallest damage on the tip, the thread will break. Find some 600 to 1000 grit emery paper and extremely gently remove any burrs.

Hardware may be

first of all do one thing and that is keep your platen marked A,B,C in b or c position then start printer if it prints then it means your shuttle gets very much tight in position A, for that please switch off the printer remove paper and loose your shuttle and adjust your shuttle according to the movement of paper. also do one thing that is clean your shuttle senser also.

The bobbin should be placed in the shuttle, with the needle at the top end travel. You can watch the shuttle move as the hand wheel is turned.
