Precise measurement is crucial when centering. Use the caliper to measure the diameter of the router bit accurately.

Example:

Assuming you are using a 1/4-inch bit, this measurement is essential for future calculations.

Step 4: Mark the Center of the Workpiece

Begin by marking the center of the piece you are routing. For rectangular or square pieces, find the midpoint of each edge and draw lines connecting opposite corners to pinpoint the exact center. For circular pieces, measure the radius from the edge to the center.

Calculating Offsets

Once you have the measurements and center marked on your workpiece, it’s time to calculate the offsets based on the router bit size.

Step 5: Determine Offset Distance

To center the router on your workpiece, subtract half the diameter of the bit from the center of the workpiece. This calculated offset will allow you to align the router accurately.

Formula

Offset Distance = (Width of Workpiece / 2) – (Diameter of Router Bit / 2)

For instance, if your workpiece is 4 inches wide and your bit is 1/4 inch in diameter, the distance to measure from the edge of your workpiece is:

4 inches / 2 – (0.25 inches / 2) = 2 inches – 0.125 inches = 1.875 inches from the edge.

Step 6: Adjust Your Router

With the offset distance determined, adjust the position of your router. Set the edge guide (if used) to the calculated distance.

Tip:

For added precision, use clamps to hold your workpiece securely as you make adjustments. This prevents it from moving while you center the router.

Step 7: Test the Centering

Before committing to your project, perform a test run. Select a scrap piece of wood similar to your workpiece and execute the planned router operation. Measure the results to confirm that the cuts are as expected. If necessary, make small adjustments to the offset until you achieve perfect alignment.

While the previously discussed method is effective, several advanced techniques can also provide precise centering for the Dewalt DW621.

Using a Centering Template

One effective way to help center your router is by using a center marking template. This template is designed to outline the exact location where the router bit will cut and relieve the need for manual calculations.

Creating a Centering Template:

  1. Cut a piece of scrap material to the same dimensions as your workpiece.
  2. Mark the center point.
  3. Drill a hole in the center where the router bit will pass through.

This template can be clamped onto your workpiece, providing a visually guided outline for centering your Dewalt DW621.

Utilizing Dowels to Center the Router

For more challenging projects or when perfect accuracy is required, you can use dowels as a centering guide:

  1. Insert dowels into pre-drilled holes on both the router base and the workpiece.
  2. Line the dowels up properly, ensuring perfect alignment with the marked center on your workpiece.

This method is particularly useful for gang routing multiple pieces of the same configuration.
