Adjusting the Fence
One of the most important steps in getting perfect mitres on a table saw is adjusting the fence. The fence is the guide that keeps the workpiece in line as it is being cut, and if it is not properly aligned, the mitres will not be accurate.
1. Check the Alignment
Start by checking the alignment of the fence. Place a square against the fence and the table saw blade, making sure they are both perpendicular. If the fence is not square to the blade, it will need to be adjusted.
2. Adjusting the Fence
To adjust the fence, start by loosening the bolts or screws that hold it in place. Use a square to check the alignment again, and make small adjustments as needed. Once the fence is square to the blade, tighten the bolts or screws to secure it in place.
It’s important to note that different table saws may have different methods for adjusting the fence, so consult the owner’s manual for specific instructions for your model.
By taking the time to properly adjust the fence, you can ensure that your mitres will be perfectly straight and accurate, resulting in professional-looking projects.
Setting the Angle
Before making mitre cuts on a table saw, it is crucial to ensure that the blade is set at the correct angle. Here are the steps to set the angle:
- Start by turning off the table saw and unplugging it from the power source for safety.
