The plastic string of a string trimmer is attached to a motor that spins it at a high speed, allowing it to cut through weeds, grass, and other plants. However, the plastic string can sometimes curve instead of pointing straight out. To straighten the string, you can cut it to length, staple each end to a piece of wood, and use a heat gun to soften the plastic. Once the plastic is soft, it can be reshaped, and after it cools down, it will retain its new shape.

What You'll Learn
Cut the line to length
Cutting the line to length is an important step in the process of straightening string trimmer plastic. When you purchase a new spool of trimmer line, the line may curve up or down instead of pointing straight out when installed in the trimmer head. Cutting the line to the correct length is the first step in rectifying this issue.
To cut the line to length, first, remove the old spool by reaching inside the cap's housing and gently pulling out the plastic disc. Take note of the orientation of the spool as you remove it. Then, cut a new piece of string that is about 8 feet long. If you have a 2-string trimmer, pull the string through the opening until you reach the middle, so you have two equal halves hanging off the spool.
Next, attach the new string to the spool. Pay close attention to how the final 5-6 inches (13-15 cm) of the thread are connected to the spool. Usually, there is a loop or opening in the spool that the end of the string goes through to secure it in place. If your trimmer has a self-winding head, simply feed the length of string through the spool and rotate the head to wind the string.
Finally, reinstall the spool and cap. Make sure not to add so much string that it extends past the rim of the spool. Leave 4-6 inches (10-15 cm) of wire at the end so that the trimmer works effectively. Now that the line is cut to length, you can proceed with the next steps to straighten the string trimmer plastic.

Staple each end to a 2x4
When you install a new piece of trimmer line, it may curve up or down instead of pointing straight out. To straighten it, you can staple each end to a 2x4. This method is useful if you want to avoid the common issue of warped 2x4s.
Firstly, cut the line to your desired length. Then, staple each end of the line to a piece of 2x4. Make sure the 2x4 is straight and not warped, as this will defeat the purpose of the exercise. If you are struggling to find a straight 2x4, you can cut a warped 2x4 along one edge in a straight line using a table saw sled. After you get a straight edge on the 2x4, you can turn it around, slide the fence in, and cut the other side of the 2x4 straight.
Alternatively, you can use the part of a warped 2x4 that is not affected by the problem. For example, if a board has a bad twist at one end, you can use the other end for a shorter piece.

Use a heat gun to soften the plastic
To straighten the string trimmer plastic, you will need a heat gun, a piece of 2x4 wood, and some staples. First, cut the plastic trimmer line to the desired length. Then, staple each end of the line down to the 2x4 wood. Now, carefully apply heat from the heat gun to the plastic line. This will soften the plastic, allowing you to mould it into a straight shape. Once it has cooled down slightly, fold the straightened line in half and staple each end down to the wood again. Finally, heat the folded end with the heat gun so that it retains its new, straight shape.
This method is effective because the heat from the gun softens the plastic, making it pliable. When the plastic is soft, it can be reshaped, and by stapling the ends to the wood, you ensure that the line stays straight as it cools. The final step of heating the folded end helps the plastic "remember" its new position, so it remains straight even after being removed from the wood.
It is important to work carefully when using a heat gun, as excessive heat can damage the plastic or even cause it to melt. Always follow the safety instructions provided with your heat gun, and take care not to touch the hot end of the gun or the heated plastic to avoid burns. Additionally, make sure to work in a well-ventilated area to prevent the inhalation of any fumes that may be released from the heated plastic.
By following these steps, you can effectively use a heat gun to straighten your string trimmer plastic, improving its performance and cutting ability.

Fold the line in half
To straighten the string trimmer plastic, you will need a few tools. Gather a heat gun, a piece of 2x4 wood, and some staples. Start by cutting the line to your desired length. Then, staple each end of the line down to the 2x4 wood. Next, use the heat gun to carefully heat up the plastic line. This will soften the plastic, making it pliable and easy to manipulate. Once the plastic is soft enough, you can begin to shape it.
The next step is to fold the straightened line in half. This is a crucial step in the straightening process. Carefully fold the line, ensuring that the two ends meet up perfectly. You don't want any unevenness or bumps along the fold, as this will impact the final result. Once you have a crisp fold, staple each end of the line down to the 2x4 wood again, holding the folded end securely in place.
Now that the line is folded and secured, it's time to apply heat to this section. Using your heat gun, carefully heat the folded end. This will help the plastic 'remember' its new position and maintain the straightness over time. Allow the plastic to cool completely before removing the staples and releasing the line from the 2x4 wood. Your trimmer line should now be straight and ready to cut weeds effectively.

Staple the ends to the 2x4 and heat
To straighten the string trimmer plastic, you will need a piece of 2x4 lumber, some staples, and a heat gun. First, cut the trimmer line to length. Then, staple each end of the line down to the 2x4. Make sure the staples are secure and that the line is taut. Once the ends are stapled down, take your heat gun and carefully apply heat to the plastic line. This will soften the plastic, allowing it to take on a new shape. Heat the plastic until it is pliable, then stop applying heat. It is important to be careful during this step, as too much heat can damage the plastic.
Now, this is where the process gets a little tricky. You want to act quickly, as the plastic will start to harden again as soon as it is removed from the heat. Carefully fold the straightened line in half, being mindful not to crease or bend the plastic. Once the line is folded, staple each end down to the 2x4 again, making sure that the staples are secure. Finally, reheat the folded end of the line with your heat gun. This step is crucial, as it helps the plastic "remember" its new position. Allow the plastic to cool completely before removing the staples and releasing the line.
The result should be a straight trimmer line that cuts weeds more effectively. This method is a great way to get more life out of your trimmer line and improve its performance. It may take a few tries to perfect the technique, but with practice, you'll be able to straighten your trimmer line like a pro. Remember always to exercise caution when working with heat guns and power tools, and always wear the appropriate safety gear.
