Installing the Circle Cutting Attachment:

The circle cutting attachment will allow you cut circles from a minimum diameter of 4” to a

maximum diameter of 12”. The circle cutting attachment will require using the palm held base if

you want to hold the router motor with the palm of your hand or the t-handle base if you want to

guide the router by holding the pistol grip base. Unscrew the sole plate from the D-shaped ring to

remove the mounting hardware from the circle cutting attachment. Place the D-shaped ring into

the top side of the base you plan to use, aligning the flat edge on the nut with the flat edge on the

through hole in the base and with the threads protruding through the bottom of the base. Place

the circle cutter arm over the exposed threads and secure to the base by threading the sole plate

back onto the D-shaped ring. Insert the router motor into the base and lock in place at the desired

height by flipping the locking lever on the base to secure the router in the base. The cut should be

made by making multiple passes, adjusting the cutting depth each time until the final cut will

allow you to completely cut through the stock thickness.

Making a Circle Cut:

To make a circle, drill a 1/8” diameter hole to a depth of 9/32” in the center of the circle for the

pivot pin to be inserted into. Adjust the pivot pin to position on the circle-cutting jig using the

scale on the side of the circle-cutting jig. Turn the knob clockwise to lock the pivot pin at the

desired diameter.

The cut is made by inserting the pivot pin into the 1/8” center hole with the router bit and router

held above the stock. Carefully turn the router on and slowly plunge the rotating router bit into

the stock until the sole plate sits squarely on the stock. With one hand holding the router or pistol

grip handle and the other hand on the ball knob on the end opposite the router, slowly rotate the

router around the pivot pin until you have completed a full circle around the pivot point. Turn the

router off and allow the bit to come to a full stop before removing the router bit from the cut.

Readjust the cutting depth and repeat until you have completed making the circular cut out.
