Before anything else, you'll need to prepare the following:

Tools and Equipment:


Now here are the steps to follow:

1. Cutting the Plywood

Remove the router's sub-base so you will know how big the end of your jig should be. After that, cut the plywood's end into a circle that is about the same size as your router's sub-base.

2. Drilling Holes

Drill holes on to the jig's circular end to match the sub-bases holes. You can use the sub-base as a guide will drilling.

3. Screwing the Jig

Screw the circular end of your jig to the base of the router. Make sure that you align the circles on the sub-base, along with the holes that were drilled on your jig.

4. Drilling Pivot Holes

Drill tiny pivot holes on the jig's arm. They should be spaced at about one inch apart.

5. Cut the Circle

Now it's time to use the jib so you can cut a circle. Draw a line on your workpiece, starting from the center until the end of your desired radius. Center the router on top of the radios' endpoint, then drive a nail into the appropriate holes in the jig, which follows the center of your workpiece.

Set the router to the right depth, then make one slow pass through your workpiece. Use the nail as a pivot point and continue to create deep cuts in several passes. In each pass, lower the router a bit.

6. Drill Holes on Block

We'll be using the second jig for cutting circles, which can be made out of scraps from your workshop. This will be attached to your router's sub-base.

Drill holes that are the same size as your dowels in one of the long edges of a 12"x1"x4" wooden block. The holes must be at the same distance as the router's base's diameter.

7. Sand the Dowels

Using the sandpaper, sand the dowel's tips well until it's smooth and ready to use.

8. Add Wood Glue

Put a bit of wood glue in the holes of the wood block. Place your dowels inside the holes of the block, then let the glue dry for a few minutes.

9. Place the Dowels on Router

Lay your dowels through the holes in the sides of your router's base.

10. Cut the Circle

Now it's time to use the jig to cut the wood into a circle! Nail the center of the block to the center of your preferred circle. Then slide your router to the right spot on the dowels. This will match the end point of your circle's radius. Set your router bit to the right depth.

Once it's ready, swing the router slowly and cut through the workpiece. Remember to use the wood block as your pivot point. Continue to repeat this process as many times as needed, lowering the router bit slowly as you make another pass.

Remember to do this slowly and with steady hands, as you wouldn't want to make a mistake and start all over! But do not go too slow, as this may break the wood you're cutting.

Once you have finally cut through the wood, you have a perfect circle to use for your next woodworking projects!

Remember to continue practicing with scrap wood until you get it right. I'm sure that as long as you continue to work on your circles and follow these steps, cutting a circle will be like a reflex to you.
