How to fix bottom bobbin in mini sewing machine
It’s quite common for mini sewing machines to have a tendency to jam during stitching operations, with the bottom bobbin being a common culprit. That’s why it’s so important to know how to troubleshoot and repair the bottom bobbin of your machine. However, before diving into fixing it, there’s a few steps you should follow to ensure you do it safely and correctly.
What to do before you start
Firstly, you need to be sure that the machine is unplugged from the electrical outlet before you proceed with any troubleshooting repair. It’s also wise to consult with the user manual of your machine for detailed instructions and a list of specific parts. This will help you identify the problem faster and guarantee safety. Additionally, it’s possible that your sewing issue may require further repairs, so it’s best to be prepared for more complex and specific interventions.
Disassemble the bottom bobbin
Begin by removing the screwdriver tool and unscrew the bottom bobbin and its housing area. When disassembling the bobbin, gently pull it out of its housing area without forcefully removing it since that may cause further damage. Inspect the bobbin’s winding spool and ensure it’s tightly wound around the spool as per manufacturer requirements since any slack or snags can cause the machine to malfunction.
Reassemble the bottom bobbin
Once the bobbin is inspected and in-order, reassemble it in the reverse order of disassembling. Ensure that you tighten all the screws correctly, paying particular attention to the tension of the bobbin case so it’s neither too tight nor too loose. Maneuver the bobbin smoothly so that all the screws and cogs are correctly in-place.
Check the stitches
For the sewing machine to function optimally, it’s essential- to ensure the tension of the stitches are in-tune. To check the tension, run a stitching test on a scrap piece of fabric and check the stitches are correctly formed and have a uniform shape, size and width. Lastly, if the bobbin and its tension screws are adjusted correctly and the stitching is even, then the fix is complete.
Safety Considerations
When attempting any repairs to a sewing machine, safety is of utmost importance. Be sure to wear protective glasses to protect your eyes from any debris, such as fabric shavings, that may fly from the machine. Keep a pair of scissors or other sharp tools away from the machine and its parts to prevent potential accidents and injuries. In addition to this, it’s wise to also wear protective gloves as a guarantee against getting splinters or losing small parts.
Conclusion
Fortunately, after following the right steps, it’s relatively easy to troubleshoot and repair the bottom bobbin of your mini sewing machine. However, keep in mind that in order to prevent future problems you should always ensure that the bobbin and its tension screws are adjusted to the correct settings before you begin stitching.
Tips to Avoid Further Issues
In order to guarantee the longevity of your mini sewing machine, ensure you follow these general tips: use only high-quality thread or yarn that is compatible with your machine, lubricate the sewing needle regularly, and avoid pinning or sewing through thick materials. These tips can help you protect your machine from potential damage.
Cleaning for Maintenance
Besides following the above-mentioned tips to prevent potential issues, it is also important to clean the machine and its parts regularly for proper maintenance. Begin by unplugging the machine and removing any fabric residues from other parts with a metal brush or pin. At this point, you should also clean the storage area and its fixtures with a piece of soft cloth. Once done, you can reassemble the parts in their correct order and then lubricate the main body of the machine with machine oil.
Preventative Troubleshooting
In order to prevent future problems, it’s a good idea to periodically check the sticking points, springs, screws and other components of your machine. Additionally, keeping your machine away from direct sunlight and a safe level of heat can also help preserve the quality of its parts. Finally, store your machine in a cool and dry place, away from potential sources of dust and electric shock.
Testing on Scrap Fabric
In order to guarantee safety and optimal stitching performance, it’s best practice to test the machine on scrap fabric before using it on fabrics of value. Begin by cutting the desired material with a pair of fabric scissors and making the appropriate markings with tailor’s chalk. Then, make sure the fabric is inserted next to the bobbin and that the tension screws of the machine are adjusted correctly. Once that’s done, you’re ready to test the sewing machine on the fabric.
