In conclusion, a straight edge is an invaluable tool for any woodworker. It improves accuracy, enhances safety, and allows for professional-quality results. Investing in a good quality straight edge is a wise decision that will pay off in the long run.
Preparing the Workpiece
Before using a table saw to get a straight edge, it is crucial to properly prepare the workpiece. The following steps outline the process:
1. Choosing the Right Piece of Wood
Start by selecting a high-quality piece of wood for your project. Look for straight-grained, stable, and dimensionally accurate stock. Avoid using warped or twisted wood as it will be challenging to achieve a straight edge.
2. Measuring and Marking
Once you have chosen the wood, mark the desired length and width on the board. Use a measuring tape or a straightedge to ensure accurate measurements. Double-check your markings before proceeding.
3. Rough Sizing
If your board is significantly longer and wider than the final dimensions, it’s best to rough cut it before using the table saw. This will make it easier to handle and reduce the risk of tear-out or blade binding during the final cut.
- Measure the length of the piece and mark the rough cut line on each end.
- Use a circular saw or a jigsaw to make the rough cuts, staying slightly outside the marked lines.
- Remove any excess material, leaving a rough piece close to the final size.
4. Joint One Straight Edge
To create a reference edge for your table saw, you need to joint one side of the board. The jointed edge will be used against the table saw fence to guide the workpiece during the final cut.
- Set up a jointer or a hand plane, ensuring it is properly aligned and sharp.
- Place the rough piece on the jointer table, with the face against the fence.
- Apply even pressure and push the board through the jointer, keeping it firmly against the fence at all times.
- Continue jointing until you achieve a straight and smooth edge along the entire length.
Once you have prepared the workpiece by following these steps, you are ready to proceed to the next stage of getting a straight edge on a table saw.
Measuring and Marking
Before you begin using a table saw to get a straight edge, it’s important to measure and mark your materials correctly. This will ensure that you achieve accurate and precise cuts.
Measuring:
Use a tape measure or ruler to measure the length and width of the material you will be cutting. Make sure to measure from the same reference point for consistency.
Marking:
Once you have taken your measurements, use a pencil or marking knife to mark the cut line on the material. Make sure to mark both ends of the material, as well as any intermediary points if necessary.
Squareness:
To ensure that your cut line is square, use a combination square or a framing square to check the angle of the line. Place the square against the edge of the material, and adjust the cut line as needed until it is perfectly square.
Using a Table Saw Fence
A table saw fence is a useful tool for making straight cuts. It is a guide that can be adjusted to ensure that your cut line is parallel to the blade of the table saw.
Setting the Fence:
Measure the desired distance from the edge of the material to the cut line and adjust the fence accordingly. Use a measuring tape or ruler to ensure accurate positioning.
Clamping the Fence:
Once the fence is set, use clamps to secure it in place. This will prevent it from moving during the cutting process and ensure that your cut remains straight.
Cutting:
With the fence set and clamped, carefully push the material through the table saw, keeping it flush against the fence. This will guide the material and help you achieve a straight edge.

1. Check the Alignment
Start by checking the alignment of the fence. If the fence is not aligned properly, it can cause your cuts to be off and affect the accuracy of your work. To check the alignment, measure the distance between the front and rear of the fence at different points along its length. The measurements should be the same. If they are not, you will need to adjust the fence to align it properly.
2. Adjusting the Fence
To adjust the fence, loosen the bolts or screws that hold it in place. Move the fence to the desired position and tighten the bolts or screws back up. Make sure to double-check the alignment after making the adjustments to ensure the fence is straight.
Some table saws have a ruler or measuring tape on the fence itself, which can help you set it to the desired position accurately. Use the ruler or measuring tape to measure the distance between the fence and the blade, and adjust accordingly to achieve the desired width for your cut.
3. Parallel to the Blade
It is crucial that the fence is parallel to the blade. To check the parallelity, use a straight edge or a piece of wood. Place it against the blade and then slide it against the fence. The straight edge or wood should make contact with the fence along its entire length. If there are any gaps or uneven areas, make further adjustments to ensure the fence is parallel to the blade.
Remember to always follow the manufacturer’s instructions for your specific table saw model when adjusting the fence. Proper alignment of the fence is essential for getting straight and accurate cuts on your table saw.
