Router Tips

The Pedestal Table!

After taking the time to turn that special pedestal leg it is important to make sure that the position of the three legs is equally spaced. Follow these simple steps to find the location of the equally spaced dovetails on the pedestal.

Making The Pattern:

The pattern is used to make sure we have three equally spaced dovetail slots on the pedestal base and that the base lies flat on the router table when cutting the dovetails.

Before making the pattern we need to know the outer most diameter of the pedestal leg. This diameter will determine the size of the triangular fixture.

Once the largest diameter of the pedestal leg has been determined, draw a circle on the 1/4" plywood pattern material. We now have to draw an equalateral triangle around this circle. Draw a line on the edge of the circle, this will be the base line of the triangle. Draw a perpendicular line through the center of the circle.

Using a 60 degree plastic template along the base line, connect the base line and the perpendicular line where it intersects the circle. Repeat on the opposite side to complete the equalateral triangle.

Now draw a line through the center of the circle 90 degrees to each base line. Our circle is now divided into six equal parts. The marks on the circle will determine where we cut our jig and also be used later for locating the fence.

Cutting & Mounting The Jig:

Cut out the main triangle shape. When making the six cuts make sure the cut is 90 degrees to the center marks. This will allow the pedestal to remain flat while cutting the dovetails.

We used a 1" flat bottom bit and a backer block when cutting the square recesses in the plywood jig. Make sure the bit is high enough that it does not interfere with the dovetail bit.

To mount the fixture on to the pedestal, drill a hole in the center of the jig and screw into place in the center of the pedestal. To keep the plywood jig from moving as the router bit cuts into the pedestal, place another screw in an offset position as seen below.

Completing The Cuts

We used a shop-made table fence with a 30-degree angle. The jig rests against the fence and the base plate keeping the pedestal leg flat when cutting the dovetail slot.
