Should The Fence On A Table Saw Be Perfectly Square
The table saw, a staple tool in any woodworker’s workshop, is known for its ability to make precise and accurate cuts. One of the key components of a table saw is the fence. The fence acts as a guide for the wood being cut, ensuring that it remains straight and parallel to the blade. While some may argue that the fence should be perfectly square to the blade, there are differing opinions on this matter.
Those in favor of a perfectly square fence argue that it is essential for achieving accurate and consistent cuts. A square fence ensures that the wood is always held at a 90-degree angle to the blade, resulting in clean and precise cuts. This is especially important when making joinery cuts, such as dadoes or rabbets, where any deviation from a perfect 90-degree angle can result in gaps or misalignments.
On the other hand, proponents of a slightly skewed fence argue that it allows for better control and versatility in cutting. They believe that a perfectly square fence restricts the ability to make angled cuts or to add a slight bevel to the edge of the wood. By allowing a small degree of skew, woodworkers can easily make angled cuts without needing to readjust the fence every time. This can save time and effort, especially when working on complex projects that require multiple angled cuts.
In conclusion, while the debate around whether the fence on a table saw should be perfectly square continues, it ultimately comes down to personal preference and the type of projects being undertaken. Woodworkers who primarily focus on precision and accuracy may find a perfectly square fence to be beneficial. However, those who value versatility and flexibility in their cutting options may prefer a slightly skewed fence. Ultimately, the goal is to find a setup that works best for each individual woodworker and their specific needs.

There are several steps you can take to prevent kickback and ensure your safety when using a table saw:
- Use a riving knife: A riving knife is a safety device that sits behind the blade and helps to prevent the wood from pinching the back of the blade, reducing the risk of kickback. Always make sure that the riving knife is properly aligned and functioning before making any cuts.
- Use a splitter: A splitter is another type of safety device that helps to prevent kickback. It is similar to a riving knife but remains fixed in position and does not move up and down with the blade. The splitter also helps to prevent the wood from closing in on the back of the blade.
- Use a featherboard: A featherboard is a device that applies pressure to the wood being cut, keeping it firmly against the fence and table. This helps to prevent the wood from lifting and reduces the risk of kickback.
- Set the proper fence distance: Ensuring that the fence is set at the correct distance from the blade is crucial for safety. If the fence is too close to the blade, it can cause the wood to get caught and kick back. If the fence is too far from the blade, it can cause the wood to bind and also increase the risk of kickback. Always follow the manufacturer’s guidelines for setting the fence distance.
- Use push sticks and push blocks: When cutting smaller pieces of wood, it is important to use push sticks or push blocks to keep your hands safely away from the blade. This helps to prevent accidents and reduces the risk of kickback.
By following these safety precautions and using the proper techniques, you can greatly reduce the risk of kickback and ensure a safer working environment when using a table saw.
Consistent and Precise Cuts
One of the main reasons why the fence on a table saw should be perfectly square is to ensure consistent and precise cuts. When the fence is not at a perfect 90-degree angle to the blade, it can lead to an uneven cut, resulting in a piece of wood that is not straight or accurately sized.
