Dont start sweating yet, Let me tell you in plain english how to Build cornhole boards. This is easy I swear. These plans work for Baggo, Corntoss, Tailgate Toss and Bean Bag Toss.
Here is the materials you will need.
A 4′x4′x1/2″ or thicker sheet of plywood. The smoother the better.
4 - 2×4x8’s
screws
Ok here we go, Cut the plywood in two so you have 2- 2′x4′ pieces.
Cut your 2×4’s you will need 4-48″s long for the sides and 4-21″s long for the fronts and backs
now lay a frame of 2 48″ boards with two 21″ boards in between them and lay the plywood on top.
Make sure all the edges are pretty flush and then screw down the plywood to the 2×4’s
Then from one end measure down 9″s somewhere close to center and put a line then from a side measure over 12″s and put a line. You need to draw the lines out until they cross. That point is center for your hole. Now center that with your 6″ hole saw and drill your hole. If you dont have a hole saw then measure out 3″ around the cross you made and use a jig saw.
Now the Legs, Cut 2 12″ 2×4s and then fasten them to the inside frame at the end with the hole
now make your other Cornhole Board and go play cornhole
