Things You'll Need
Instructions
Use your straight edge and a pencil to measure off a 4-foot-by-2-foot section of the plywood sheet--4-by-2 is the official size of a cornhole board.
Cut the markings with a table saw. Save the pieces you just cut off because you'll need them for the back of the ramp.
Use a tape measure and mark a point that is 9 inches from the back of the 4-by2 board (you will be measuring from one of the short sides). This mark should also be centered. You will be using this mark to indicate where the hole in the board should be.
Draw a circle 6 inches in diameter, using the mark you just made as the top of the circle. This means the top of your circle should be 9 inches from the top of the board.
Cut along the lines of the circle with a sabre saw to create a hole--this will be what you'll be aiming for during the game.
Cut a piece from the wood left over when you cut the 4-by-2 cornhole board by using the table saw. This piece should be 2-by-1; it will serve as the back stand of the board.
Cut a 10-degree angle on the top of 2-by-1 piece of wood. This slight angle will allow the cornhole board to rest flat on the stand.
Place the cornhole board on the back stand. The end with the hole should be resting on the stand; the other end of the board should be resting on the floor. This means the hole will be elevated off the floor.
Fasten the stand to the cornhole board by hammering the nails into the top of the board and into the stand.
