How to Build a Barn Ramp

Hold a 120-inch board against the floor of the barn. You do not want to use these plans for a floor that is higher than 4 feet off the ground. With your angle finder, measure the angle between the board and the ground and the angle between the board and the barn. You will attach the ramp to the ledger board that is right below the barn floor.

Lay your board flat and draw a line on the board using your straightedge to match the angles. Repeat this step on each board. When the boards are cut along these lines and positioned against the building, there will be no corners that stick into the ground or push against the building.

Cut along the lines using your circular saw. All of the boards should have the same dimensions. The more precise your cuts, the more likely your ramp will will be level.

Position the 120-inch boards on edge, parallel and spaced 10 ½ inches apart. The cut edges should be facing upward and aligned between the boards. Screw a 48-inch board to the ends that were cut to match the barn floor so the sides of the two outside boards are flush with the ends of the 48-inch board. Use twelve screws for this task.

Position the four boards and the 48-inch board against the ledger board. The angled cuts to match the ground should be flat on the ground. The 48-inch board should be 1 ½ inches below the floor-top. Screw the 48-inch board to the ledger board using twelve screws. Use four screws between each 120-inch board.

Lay the rest of the 48-inch boards perpendicularly on top of the 120-inch boards so their ends are flush with the sides of the 120-inch boards. Space the boards ½ inch apart. Screw the 48-inch boards to the 120-inch boards using six screws for each board.
