Before you begin, ensure that your table saw is unplugged. Even a momentary lapse in attention can result in serious injuries if the saw is accidentally powered on while you’re working on it. Wearing safety glasses is also recommended to protect your eyes from dust and debris.
2. Remove the Blade Guard
Start by removing the blade guard or any obstruction from your saw’s blade to provide an unobstructed view of the blade and the miter slot. This way, you can gauge the alignment more effectively as you work.
3. Adjust the Blade Height
Set your blade to a height that is about 1/8 inch above the thickness of the material you will mostly be cutting. This elevation offers maximum visibility and the most accurate view of the blade’s relationship with the miter slot.
4. Measure the Alignment
Now comes the critical part of the alignment process. You’ll want to ensure that the blade is parallel to the miter slot.
Using a Straight Edge
-
Place the Straight Edge: Lay your straight edge across the table saw so that it runs parallel to the miter slot. It should be touching the blade without moving the blade itself.
-
Identify the Gap: Measure the distance from one end of the straight edge to the blade at two points: the front and the rear of the blade.
-
Note the Measurements: Write down these two measurements.
Analyze the Measurements
If the distance is not the same in both places, your blade is out of alignment. The acceptable variance in measurements is typically no more than 0.002 inches. If your measurements exceed this, it’s time to make adjustments.
5. Adjust the Blade Alignment
To adjust the blade’s alignment, you will need to tweak the trunnion bolts or the alignment screws, which connect the blade assembly to the saw.
Locating the Adjustments
-
Identify the Location of the Bolts: Refer to your Dewalt table saw’s user manual to find the location of the alignment screws or trunnion bolts.
-
Make the Adjustment: Using your wrench, make tiny adjustments to the alignment bolts. It’s crucial to go slow—small turns can result in significant changes to blade alignment.
Re-Measure for Accuracy
After making adjustments, repeat the measuring process with your straight edge:
-
Recheck the Measurements: Measure again at the front and back of the blade.
-
Ensure Consistency: Keep adjusting until both measurements are within the acceptable range of 0.002 inches.
6. Finalize Blade Height and Stability
Once you’ve achieved the desired blade alignment, it’s time to set the blade height again:
-
Re-adjust the Height: Reset the blade height to your original setting (1/8 inch above the thickness of the material).
-
Check Stability: Make sure the blade is firmly in place and does not wobble. Wobbling can lead to inaccurate cuts and dangerous situations.
7. Test the Alignment
Before getting back to your project, it’s wise to conduct a test cut. Here’s how to do that:
-
Prepare a Test Piece: Take a scrap piece of wood similar to the material you plan to use.
-
Make the Cut: Feed it through the saw slowly and steadily.
-
Analyze the Cut: Examine the cut edge—there should be no binding or chipping, and it should be straight and smooth.
