Ultimate Circle Cutting Trim Router Jig

*Ignore the "scratches" in the photos. They are on the removeable clear plastic protective film that all of our acrylic components ship with.*

In the 14th-century Italian painter Giotto demonstrated his skill to a messenger from Pope Benedict XI by drawing a perfect red circle with one brushstroke. For the rest of us, there is the Crafted Elements circle making jig.

We figured it was as good a time as any to throw our hat into the "Circle Cutting Router Jig" ring. By no means is this a revolutionary product. However, it is an incredibly functional one that you'll wonder how you ever lived without.

Available in two different sizes and designed to be compatible with most common trim routers from Rigid, Ryobi, Dewalt, Makita, Milwaukee, Bosch and more (see the full compatibility list below). The small sizes enables the creation of circles between 6" and 24" in 1" increments. The large size is a behemoth and is ideal for table making with a range of 6" to 55" in diameter in 1" increments.

How does this simple yet useful piece of plastic make circle shaping a breeze? Simply attach any compatible trim router and a 1/4" diameter cutting bit. Nail a 9 or 10 gauge nail or #8 screw into the hole corresponding to the diameter of the circle you wish to cut. Keep in mind that you'll want to be working on the BOTTOM side of your workpiece, as you will be left with a small center hole left over once you remove the jig. The nail/screw acts as your center rotation point. Slowly rotate the router around the perimeter keeping your bit at an appropriate cutting height. Depending on the thickness of your workpiece you may have to do this in multiple passes, lowering the router bit with each consecutive pass to get a progressively deeper cut.

Alternatively you can create an initial circle that only penetrates 1/4-1/2" through your workpiece. Then, using a jigsaw and the recessed area you've created as a guide rough-cut around the entire circle. Then remove the excess material using a flush trim router bit, letting the bearing glide along the recess you initially created with the jig.

Don't get left making circles by hand! Use this handy jig along with any compatible trim router (and 1/4" bit) to produce beautiful, accurate circles without the fuss.

Note: Our circle jigs are calibrated to work with a 1/4" diameter router bit (with a 1/4" diameter cutter). Using a smaller or larger diameter bit will result in a positive or negative offset. No router mounting screws are provided. You'll need to remove your OEM router base to install this jig (as it effectively acts as a router base). We suggest using your OEM router base screws to attach your router to this acrylic jig. Recessed holes to match your routers hole pattern are built into the jig.

If your router is not listed in the table above but has an OEM router plate of 6" or less you can still use this jig. You'll simply need to drill your own mounting holes. Check out this helpful video on how to drill your own mounting holes in our router bases.
