Why Is Sewing Machine Timing so Important
Setting the proper timing on a sewing machine is critical to proper maintenance and operation of the machine. The timing of the machine is the distance in which the needle bar and the needle plate move from the highest point to the lowest point on the arm of the machine. If the timing is not properly set, the machine will not stitch correctly and can be a safety hazard due to possible needle breakage.
The importance of setting the timing on a sewing machine can not be understated. Poor timing can lead to broken needles, skipped stitches, tension problems, and inaccurate seam allowance. It’s also important to remember that sewing machines tend to need regular timing adjustments due to normal wear and tear of the parts.
Tools and Materials Required
To properly set the timing on a sewing machine, most people will need to have both the appropriate tools for the job, as well as any necessary timing parts for the machine. Some of the tools that may be necessary include a screwdriver, level, feeler gauge, and a small wrench. Depending on the make and model of the machine, it’s also possible that you may need additional supplies.
When it comes to the timing parts on the machine, it’s important to make sure you have identified all the parts that need to be replaced. There should be a diagram/photo that comes with the machine, as well as any accompanying literature, which will help identify the parts that need to be replaced. Additionally, a lot of machines may have extra timing plates or screws, which will also need to be replaced.
Steps to Set the Timing
Once you have the necessary tools and parts, you can begin the timing process. Most sewing machines should have a timing lever and or a timing wheel or screw. With some machines, this lever/wheel needs to be adjusted in order to properly set up the timer. With others, reversing the direction of the machine by using a timing screw can also help in setting the timing correctly. Once you have identified and adjusted the lever/screw as required, it’s time to check the timing.
To do this, you will need a feeler gauge, which will measure the gap between the needle bar and the needle plate. The distance between the two should be around 0.8mm, which is the correct setting for your machine. If the distance does not match the ideal setting, you will need to adjust the timing screw or lever in order to get the right measurement. It’s also important to check the tension on the thread as this can also affect the sewing machine’s timing.
Checking the Timing and Finishing Up
Once you think the timing is correctly set, you will need to check the tension by putting a piece of fabric in the machine and running it through. The stitch should be uniform, even, and the tension should be right. If it’s not, then you will need to adjust the tension.
It’s also important to do a visual inspection of the timing wheels, tension springs, and hook assembly to make sure everything is in working order. This is a good idea to do as regular maintenance as it will ensure that the machine is running smoothly and efficiently.
Regular Maintenance and Troubleshooting
Regular maintenance is key when it comes to the proper operation of a sewing machine. It’s important to make sure that any parts that have been replaced are properly re-timed and functioning correctly. Additionally, if there’s an issue with the machine such as a skipped stitch or tension problems, it’s a good idea to check the timing as this could be the cause of the issue.
It’s also important to make sure that the machine is cleaned and oiled regularly, as not doing so can lead to damage to the machine. Additionally, if the machine is running slowly, it could be the case that the belt is worn out and needs to be replaced. This can also cause issues with the timing of the sewing machine.
Correcting Wrong Timing on a Sewing Machine
If the timing on a sewing machine is off due to improper assembly or neglect, it’s important to correct it as soon as possible. Most machines have a wheel or lever that is used to adjust the timing. If this was adjusted in the wrong direction, it can cause the needle to jam or break. It’s important to carefully adjust the wheel or lever until the needle bar is at the correct height.
Additionally, if there are any components that are loose or worn, it’s important to replace them as soon as possible. This can be a very easy process as long as you have the right tools, replacement parts, and diagrams. Once the parts have been replaced, very little fine tuning should be required.
Conclusion
Setting the timing on a sewing machine can sound like a daunting task, but with the right tools and parts, it can be a relatively simple process. In most cases, it’s as simple as adjusting the wheel or lever, checking the gap between the needle bar and the needle plate, and making any necessary tension adjustments. It’s important to remember that performing regular maintenance on the machine and replacing any worn components can help avoid any potential issues with timing.
