Set the 61-by-48-by-3/4-inch plywood on the sawhorses. Measure from one corner and make a mark at 40-inches on the 48-inch edge. Drive the 4-penny nail on the face of the plywood at that 40-inch mark.

Hang the end of the chalk box line on the nail. Pull the string of the chalk box down to the diagonal corner and pop a line on the plywood. The chalk line represents the slope of the bank ramp. It is 72 15/16-inches in length.

Cut the chalk line on the plywood with the circular saw. Trace the pattern of this piece on the remaining piece of the 61-by-48-by-3/4-inch plywood. Cut with the circular saw.

Stand one of the pieces on the ground on its sloped edge. Butt the ends of five of the pieces of 2-by-4-by-46 1/2-inch lumber against the plywood. Secure them through the plywood with the 2-inch deck screws. Space them on 12-inch centers with the first and the last ones 12-inches from the ends of the slope. Secure the other sloped piece to the lumber..

Hold two pieces of 2-by-4-by-46 1/2-inch lumber between the 40-inch edges of the sloped pieces, so that the widest part of the lumber is even with the 40-inch edge. Secure one of them as close to the top as you can. Secure the other at the bottom with the 2-inch deck screws. Repeat this with the remaining 2-by-4-by-46 1/2-inch lumber on the 61-inch edge. Space them evenly between the ends of the 61-inch edge.

Turn the bank ramp frame upright. Lay the 73-by-48-by-3/4-inch plywood on the bank ramp frame. Secure it to one sloped edge of the frame with the 2-inch deck screws, aligning it as you go. Secure it to the other sloped edge and then to the 2-by-4-by-46 1/2-inch lumber.

Build three frames by securing the 2-by-4-by-21-inch lumber between the 2-by-4-by-39 1/4-inch lumber with the 3-inch deck screws. Secure the frames to the 2-by-4-by-46 1/2-inch pieces on the backside of the bank ramp with the 3-inch deck screws. Place a carpenter's level on them vertically to keep them plumb.

Hold the 2-by-4-by-48-inch lumber under the top pieces of the backside of the frame. Secure it to the frames through the top and sidepieces of the frames with the 3-inch drywall screws. Secure the 24-by-48-by-3/4-inch plywood on top of the frame at the top of the bank ramp.
