Why Does My Table Saw Not Cut Straight
Table saws are an essential tool for any woodworking enthusiast. They allow you to make precise cuts with ease, but what do you do when your table saw isn’t cutting straight? This can be a frustrating problem, as it can lead to inaccurate cuts and wasted material. However, with a little understanding of the common causes and some simple fixes, you can get your table saw back on track.
One of the most common reasons for a table saw not cutting straight is a misaligned fence. The fence is the guide that runs parallel to the blade and helps to keep your cuts straight. If the fence is not properly aligned, it can cause the material to bind against the blade, resulting in an uneven cut. To check if your fence is aligned correctly, use a straight edge to compare it to the path of the blade. If there are any deviations, you may need to adjust the fence using the adjustment screws or bolts.
Another possible cause of a table saw not cutting straight is a dull or misaligned blade. Over time, blades can become dull or warp, which can lead to inaccurate cuts. To check if your blade is the problem, inspect it for any signs of damage or wear. If you notice any issues, it may be time to replace or sharpen your blade. Additionally, make sure that your blade is properly aligned with the miter gauge slots, as this can also affect the straightness of your cuts.
Finally, it’s important to consider the quality of your table saw itself. Cheaper or older models may not have the same level of precision and accuracy as higher-end models. If you find that your table saw consistently struggles to make straight cuts, it may be worth investing in a new saw that offers better stability and alignment. Remember, the quality of your tools can have a significant impact on the quality of your work.
In conclusion, there are several reasons why your table saw may not be cutting straight. It could be due to a misaligned fence, a dull or misaligned blade, or the quality of your table saw itself. By understanding these common causes and taking the necessary steps to fix them, you can ensure that your table saw is cutting straight and producing accurate cuts for all your woodworking projects.
Common Causes of Poor Table Saw Accuracy
When using a table saw, it can be frustrating when the cuts are not coming out straight and accurate. There are several common causes for poor table saw accuracy that you should be aware of:
1. Improper Blade Alignment
One of the most common reasons for a table saw not cutting straight is improper blade alignment. If the blade is not aligned correctly with the miter slot or the fence, it can lead to inaccurate cuts. Make sure to check the alignment of the blade regularly and adjust it if necessary.
2. Dull or Damaged Blade
A dull or damaged blade can also cause poor table saw accuracy. If the blade is not sharp enough or has teeth that are chipped or worn, it will struggle to make clean and accurate cuts. Regularly inspect and replace blades as needed.
3. Inadequate Fence Support
If the fence on your table saw is not properly supported, it can lead to inconsistent cuts. Make sure that the fence is securely attached to the table and is straight and parallel to the blade. If necessary, use additional support devices to ensure stability.
4. Incorrect Blade Height
The height of the blade can also impact the accuracy of your cuts. If the blade is too low or too high, it can result in cuts that are not straight. Use the height adjustment mechanism on your table saw to set the blade at the appropriate height for your desired cut.
5. Improper Technique
Lastly, poor table saw accuracy can also be caused by improper technique. Make sure that you are applying steady pressure and feeding the material evenly through the blade. Avoid pushing or pulling the material too forcefully, as it can lead to crooked cuts.
By addressing these common causes of poor table saw accuracy, you can improve the quality of your cuts and achieve straighter and more precise results.
Misalignment of Blade and Fence
One of the common reasons why a table saw does not cut straight is the misalignment of the blade and fence. The blade and fence should be parallel to each other in order to make accurate cuts.
Causes of Misalignment
There are a few possible causes of misalignment between the blade and fence:
1. Improper setup: If the table saw was not set up correctly during its initial assembly, it may result in misalignment. This could include the blade not being aligned correctly to the miter slots or the fence not being adjusted properly.
2. Wear and tear: Over time, the table saw components can experience wear and tear, which can lead to misalignment. This could include the fence or blade becoming loose or shifting out of place.
How to Correct the Misalignment
1. Check the setup: Start by checking if the table saw was set up correctly. This includes making sure the blade is aligned parallel to the miter slots and that the fence is adjusted properly. Refer to the table saw’s manual for specific instructions on how to adjust these components.

3. Use a straight edge: To check if the blade and fence are parallel, use a straight edge or a piece of material with a straight edge. Place it against the fence and then the blade, and compare the two. If they are not parallel, adjustments will need to be made.
4. Adjust the fence: If the fence is misaligned, adjust it by loosening the bolts or screws that hold it in place, then slowly move it until it is parallel to the blade. Tighten the bolts or screws once it is properly aligned.
5. Align the blade: If the blade is misaligned, refer to the table saw’s manual on how to align it correctly. This may involve adjusting the trunnions or using shims to make precise adjustments.
By properly aligning the blade and fence, you can ensure that your table saw cuts straight and accurately. Regular maintenance and checks for misalignment will help maintain the performance of your table saw over time.
Dull or Incorrect Blade
If your table saw is not cutting straight, one possible reason could be a dull or incorrect blade. Over time, blades can become dull, which can cause them to veer off course and make inaccurate cuts. Additionally, using the wrong type of blade for the material you are cutting can also result in crooked cuts.
It is important to regularly inspect and replace your table saw blade when it becomes dull. A dull blade can put unnecessary strain on the saw motor and can also increase the risk of kickback.
When choosing a blade for your table saw, make sure to select the appropriate type for the material you will be cutting. Different blades are designed for cutting different materials, such as wood, plywood, or metal. Using the wrong blade can cause it to bind or wander off the desired cutting line.
To ensure straight and accurate cuts, remember to always use a sharp and properly matched blade for your table saw.
Tips:
- Regularly inspect and replace the blade when it becomes dull.
- Select the appropriate blade for the material you are cutting.
- Take proper safety precautions, such as wearing protective eyewear and using a push stick.
Inaccurate Miter Gauge
An inaccurate miter gauge can be another reason why your table saw is not cutting straight. The miter gauge is responsible for guiding the workpiece at the desired angle when making angled cuts. If the miter gauge is not calibrated accurately, it can lead to uneven cuts and a lack of precision.
Here are a few factors that can cause an inaccurate miter gauge:
1. Misalignment
A common issue with the miter gauge is misalignment. The gauge may not be aligned parallel to the saw blade, causing the workpiece to veer off course during cuts. To fix this, check if the miter gauge is properly seated in its slot and adjust it accordingly. Additionally, ensure that the gauge’s fence is perpendicular to the table surface.
2. Worn or Loose Parts
Over time, the miter gauge’s parts can become worn or loose, leading to inaccuracies. Check for any signs of wear on the miter gauge’s components, such as the bar and locking mechanism. Tighten or replace any loose or worn parts to improve accuracy.
Note: It’s also worth mentioning that some table saws come with stock miter gauges that are known for their lack of precision. Upgrading to a high-quality aftermarket miter gauge can significantly improve the accuracy of your cuts.
Properly maintaining and calibrating your miter gauge is crucial to ensure accurate and straight cuts. Regularly check for misalignment, loose or worn parts, and consider upgrading to a better miter gauge if necessary. With a properly functioning miter gauge, you will be able to achieve precise and straight cuts on your table saw.
Poor Quality Materials
One possible reason why your table saw is not cutting straight is due to the use of poor quality materials. When your table saw is made with low-quality components or materials, it can result in a lack of stability and precision during the cutting process.
Low-grade materials can lead to issues such as excessive vibration, flexing, or even inaccurate measurements. For example, if the tabletop of your table saw is not made from a sturdy and flat material, it may warp or bow over time, leading to an uneven cutting surface.
In addition, the quality of the saw blade itself can greatly affect the straightness of your cuts. A low-quality blade may have uneven teeth, dull edges, or improper tension, causing it to drag or wander during cutting, resulting in crooked cuts.
How to Address the Issue:
If you suspect that poor quality materials are the cause of your table saw not cutting straight, there are a few steps you can take to address the issue:
- Check the tabletop for any warping or unevenness. If necessary, consider replacing it with a higher-quality tabletop that is flat and sturdy.
- Inspect the saw blade for any damage or signs of wear. Replace it with a high-quality blade that is suitable for your cutting needs.

Incorrect Feed Speed
If your table saw is not cutting straight, one possible cause could be an incorrect feed speed. The feed speed refers to how fast or slow you are pushing the material through the blade. If you are not feeding the material at a consistent speed, it can result in a crooked or uneven cut.
When feeding the material too quickly, the saw blade may not have enough time to properly cut through the material. This can cause the blade to bind or deflect, resulting in a cut that is not straight. On the other hand, if you feed the material too slowly, the blade may have a tendency to wander, leading to an inaccurate cut.
How to adjust the feed speed:
To ensure a straight cut, it is important to find the right balance in feed speed. Start by adjusting the feed rate to a moderate pace to allow the blade to cut through the material smoothly. Avoid forcing the material through the blade, as this can lead to binding or kickback.
Experiment with different feed speeds:
Depending on the type of material you are cutting and the blade you are using, you may need to adjust the feed speed accordingly. Slow down your feed rate if you notice the blade deflecting or if the cut is not straight. Similarly, if you find that the cut is burning the material or the blade is getting bogged down, try increasing the feed speed slightly.
Use a push stick:
When feeding the material through the table saw, it is important to use a push stick. This will keep your hands safe and allow for better control over the feed speed. A push stick also helps to maintain a consistent feed rate, resulting in a straighter cut.
Note: It is always recommended to consult the manufacturer’s instructions and safety guidelines for your specific table saw model.
Lack of Maintenance and Cleaning
One common reason why a table saw may not cut straight is due to a lack of maintenance and cleaning. Over time, dust, debris, and build-up can accumulate on the saw blade, the fence, and other parts of the saw, causing them to become misaligned or worn out. This can result in the saw not making accurate and straight cuts.
Regular maintenance and cleaning of your table saw is essential to ensure its optimal performance. Here are a few steps you can take:
Clean the Saw Blade
The saw blade can become covered in pitch, resin, or sawdust, which can affect its ability to cut straight. Use a blade cleaning solution or a mixture of water and soap to clean the blade. Gently scrub the blade with a soft brush or a cloth to remove any debris. Be sure to follow the manufacturer’s instructions and take appropriate safety precautions when cleaning the blade.
Check and Adjust the Fence
The table saw fence plays a crucial role in guiding the workpiece and ensuring straight cuts. Inspect the fence for any signs of damage, misalignment, or wear. If necessary, adjust the fence to make sure it is parallel to the blade. Refer to your saw’s manual for specific instructions on how to adjust the fence.
Additionally, make sure the fence is clean and free from any debris that may obstruct its movement or cause inaccuracies in cutting.
Note: Always disconnect the table saw from the power source before performing any maintenance or cleaning.
By regularly maintaining and cleaning your table saw, you can help prevent issues that may cause it not to cut straight. Taking the time to properly care for your saw will not only ensure accurate cuts but will also extend its lifespan.
