Cut boards to size
Follow the Cutting List and crosscut your boards with a miter saw to the correct size.
Round ends of the sides (part F) with jigsaw
Mark 1-3/4-in.-radius circles at the ends of the sides (part F). I traced a 1-qt. measuring cup to get the arc. Clamp the board to the work surface and cut along the line with a jigsaw. Sand the arcs smooth with low-grit sandpaper.
Fasten together the base
Drill pilot holes and fasten the long base parts (B) into the ends of the short base parts (A) with 2-in. construction screws. Attach the base supports (part E) to the rest of the base. These pieces will shore up the base and give the legs a place to sit.
Create the ramp
Drill pilot holes and fasten the struts (part D) to the sides of the plywood ramp (part C) with 1-1/4-in. construction screws. Set the ramp on a 3/4-in. scrap piece to get the correct spacing. Lay the sides (F) against the edge of the ramp and fasten with pilot holes and 2-in. construction screws. I used four screws for each side.
Attach the ramp to the base with the hinges
Clamp the hinge support (part G) to one of the short sides of the base. Mark the centers and make sure they match up when clamped. Fasten the 12-in. hinge to both the base and hinge support. Flip the hinge closed and use a scrap 1×4 and shim to keep the hinge support flat. Lay the ramp assembly onto the base, plumb the hinge end, and fasten the ramp to the hinge support with five pilot holes and five 1-1/4-in. construction screws.
Fasten the legs to the ramp
Round one end of the 1×2 leg boards (part H). Gang up the two legs and drill a 1/4-in. pilot hole into that end of the boards. Attach the leg supports (part J) with two 2-in. construction screws 3 in. from the non-hinge end of the ramp. Drill a 1/4-in. pilot hole through the ramp sides (F) and leg supports (J). Fasten the legs 5 in. from the end of the ramp to the inner edge of the leg supports with 1/4-in. x 3-1/2-in. carriage bolts, 1/4-in. washers and 1/4-in. nylon bolts.
Staple on the carpet
Cut the carpet to size (part L) with a utility knife or carpet cutter. Staple the carpet to the ramp with a staple gun.
