Tips for Repairing a Sewing Machine

When individuals are learning how to use and maintain a sewing machine, mistakes are inevitable since they constitute part of the learning curve. A skilled seamstress can also face challenges due to dreaded skipped stitches, broken needles, thread bunching or general machine breakdown. Stitches that turn out puckered, loopy or uneven might be signs of inappropriate pressure on the pressure foot, a misaligned needle, worn-out tension disks or an insecure needle plate. Nevertheless, it is important to understand the mechanics around your sewing machine regardless of whether you are a novice with needles or a seamless pro.

As your machine gets older, there is a likelihood that it will require periodic checkups to identify any faulty parts that need to be replaced before the problem grows worse. However, there are some tricks you can learn to fix your machine at home instead of having to pay someone else to do so. The following are examples of common tips for repairing a sewing machine:

When a thread is bunching under the fabric, it implies that the top has a perfectly straight stitch while a “bird’s nest” is formed on the bottom. A seamstress may assume that this inconsistency is caused by the bobbin, but this might not be the actual cause. They fail to acknowledge that the thread can snarl under the fabric due to decreased tension on the upper thread. The best remedy to this drawback is to raise the presser foot lifter and rethread the machine. The tension mechanism will open up to receive the thread. Depending on the description given in your machine’s manual, you will also be required to raise the needle and the take-up lever to the highest position. This helps confirm that the right tension has been obtained.

If the stitches are skipping entirely or coming out uneven, there is a high chance that the needle is damaged or broken. According to expert recommendation, the needle should be replaced after every sixteen hours of stitching time. This problem can also arise if the fabric is mishandled while sewing. If you develop a tendency of making the fabric go through the sewing machine by pulling the fabric forcefully from behind, the outcome might be unclean stitching or machine breakage. This technique of force-feeding the fabric might work against the metal teeth-like ridges known as feed dogs that grip the bottom of the fabric, making it move further from the needle during stitching. Refraining from force-feeding the fabric is the best way to avoid this problem.

If the needle keeps breaking, you might be using the wrong needle. The size of the needle determines the machine’s output, and selection of the right size can lead to improvement in its performance. Needle sizes range from eight to eighteen. However, each size has a specified function. A needle of size nine or eleven is ideal for delicate, lightweight fabrics such as organza, silk or chiffon. On the other hand, a needle of size fourteen is ideal for medium-weight fabrics such as linen, flannel and synthetic suedes. A needle of size sixteen or eighteen is preserved for heavyweight fabrics such as denim due to its strength. Therefore, using a needle of size nine to sew denim will automatically break the needle. Also, remember to check whether you are using the appropriate type of tip. A needle can either have a regular point, ballpoint or wedge point.

If the threads begin knotting up together or get jammed in the sewing machine, examine both bobbin and spool threads to confirm whether they are sticking out toward the sewing machine’s backside. Putting the threads in the right direction prevents them from twisting up in the stitching. Also, ensure that the sewing starts a few mm from the edge of the fabric. To avoid the occurrence of gaps in the stitching, back tack a bit. If there is insufficient fabric under the needle when stitching begins, tangling up of the spool thread with the bobbin thread that lay underneath it might occur and cause knots.

Sometimes the sewing machine might jam and stop sewing. When this problem occurs, it is advisable to remove the fabric you were trying to sew. For safe removal, gently tug at the fabric and lift it slightly to snip at the sewing threads until the fabric is detached from the machine. After that, remove all the jammed threads before you begin to sew again. Remember also to examine the needle and confirm that it is not bent since it could also be the cause of the problem.

Improper winding of the bobbin might cause the lower thread to break. Regardless of whether the bobbin is wound on top of the hand wheel, inside the machine or on the front side next to the hand wheel, the main “bobbin” rules apply. The bobbin should be wound with a complete thread evenly and across to form level layers. However, refrain from winding it so full that it poses a challenge while inserting it in the bobbin case. Some newer models of sewing machines are fitted with a device that enables an automatic “shut off” when the bobbin gets full, but if your model does not, you will need to be aware of this precautionary measure. The spool and bobbin thread should not have varying sizes unless you intend to do some specialty sewing or sewing machine embroidery. If different weights of sewing threads in the bobbin and on the spool for general sewing are used, ragged stitches and other complicated stitching problems will arise.

Tightening the screws of the sewing machine is another important repair mechanism. Loosening of the screws used to join the various parts of the sewing machine may make it rattle unnecessarily. It is recommended to examine loose parts on a regular basis and tighten the visible screws and bolts. Nonetheless, caution should be taken to avoid over tightening the screws to avoid minor problems.

Always give the machine a break after prolonged hours of sewing to avoid overlooking its problem. Although this repair technique might sound irrelevant, it is vital since it eliminates vague assumptions. Constant usage of the machine can make it overheat and begin to malfunction. Overheating occurs when the fibers get trapped in the bobbin or if you fail to oil the machine. This problem is normally indicated by a burnt smell.

If your machine is producing clunking, banging and grinding noises, it needs thorough examination since this might be a signal of minor problems that could result in a major breakdown. These signals might be indicators that a key part of the machine has jammed or is rubbing. Frequently cleaning and oiling the machine can eliminate this problem. Make sure to follow the guidelines outlined in the sewing machine manual for guidance during oiling or cleaning.

It is recommended that you use the above tips to repair a sewing machine before a problem gets worse. These repair tactics help in mitigating the damage that could result in costly repairs. If the sewing machine develops a solvable mechanical problem, the user can immediately fix the problem and later obtain help from technicians if the problem persists. Periodic replacement of worn-out parts may prevent frequent breakdowns and other minor problems that lead to poor sewing. However, it is important to keep tools such as screwdrivers, tweezers, an emery cloth, small brush and sewing machine oil somewhere close since they aid in repairing the machine. It is also advisable to lubricate the sewing machine regularly to prevent unexpected breakdowns and solve minor problems.

So, whether you have a heavy duty sewing machine, a sewing machine for beginners, a sewing machine for quilting or even a Brother sewing machine, I hope you found this post useful.
