With this simple jig, you can cut out a perfect size circle with just a jigsaw. Before you put everything together lets drill the anchor holes into the Side Anchor board for the Jigsaw holder. Once the circle is cut using your new Jigsaw circle jig unscrew the anchor point and you will have yourself a perfectly round circle.
Align the edge of the saw’s foot with one end of the hardboard and cut a slot for the blade. Mark a line on the bottom face of the base parallel to the edge and aligned with the blade teeth. Measure from the inside edge of the blade and mark your desired radius along the line.
Straight lines can be accomplished with a fence, but a perfect circle. Now, draw your circle with a compass or a circle guide. You’d cut one perfect circle as a guide, then cut out a slightly larger circle from your final material.
