A recessed groove in the jig lets you slide the center pivot pin (your center point) up or down the length of the jig to find the correct, exact diameter of your circle. Use the 4-star knob to tighten the T-bolt with the center pivot pin installed and you're ready to go!
This jig's base is made from phenolic plywood. Its durable, slick surface is perfect for supporting the workpiece as you rotate it through the cut. An adjustable pivot pin on a heavy-duty aluminum bar allows you to cut circles up to 38" in diameter. Finally, a unique stop system lets you align the pivot pin with the front edge of the blade.
The Rockler Ellipse/Circle Router Jig lets you cut circles and ellipse shapes over a wide range of dimensions and proportions. With your router and this handy, easy-to-use jig, you'll be able to make picture frames, mirrors, signs, tabletops and more in just a matter of minutes.
