I used a router with a circle cutting jig, but you can use a jig saw.
Step 1: Materials Needed....
1 - 4x8 sheet plywood (have your favorite home store but in half for easier handling)
4 - 2x4x8 (I used studs, but the key is to find the straightest boards you can)
2-1/2" wood screws
1-1/2" wood screws
I also used a router and chop saw, but if you only have a jig saw, it is perfect by its self.
Step 2: Cut ... It ... Out ...
measure and cut out your circles. (print out the plans, on how to lay out your circles.
