Remove the hinges from the cabinet door from where you want to install your tilt-out clothes hamper.
Cut two pieces of pegboard for the hamper sides. These pieces should be the same size. The height of each piece should be 4 inches shorter than the cabinet door on the front side (the side that will attach to the cabinet door) and 10 inches shorter on the back side. The depth of each piece should be 4 inches less than the inside depth of the cabinet where the tilt-out hamper will be installed.
Cut a third piece of pegboard for the back of the hamper. The back piece should be the height of the side piece's shortest end and the width should be 4 inches less than the cabinet door's width.
Attach a piece of 1-inch by 2-inch framing lumber to the bottom edge of the back piece using wood screws. The length of this piece of lumber should be the exact width of the bottom of the pegboard's back piece. The pegboard should fit flush with the bottom of the framing lumber.
Cut two lengths of framing lumber to attach to the edges of the back piece. These pieces should be screwed to the back piece flush with the outside edges on the same side as the bottom piece of framing.
Reinforce the joining point of the side frames and the bottom frames with L-shaped braces screwed to the inside of the right angle.
Place one side piece against the side of the back piece, with the short side joining the back piece. Measure the distance from the bottom framing board to the front edge of the side piece. Cut a length of framing board and screw it to the side piece. The front of the frame should be flush with the front of the side piece. Repeat for the other side piece.
Attach side pieces to the back piece with screws. Reinforce joining points with L-shaped braces.
Measure the front edge of each side piece from the top to the framing lumber. Cut framing lumber to attach to this front edge. Use screws to attach framing pieces. Reinforce joining points with L-shaped braces.
Measure the inside of the bottom of your hamper bin from the outside edge of one frame to the other. Cut another frame piece and attach with long screws, forming a complete rectangle of framing at the bottom of your bin. Reinforce all joining points with L-shaped braces.
Measure the inside dimensions of your hamper bin. Cut a piece of pegboard to fit the bottom. Slide the pegboard into the bottom of the bin. Attach with screws to the frame.
Attach the cabinet door to the opening with invisible hinges or piano hinge. Place hinges at the bottom so the door will tilt forward when opened.
Open the cabinet door and brace for support with a padded stool or other sturdy padded item to prevent scratching or marring the door. Place the hamper bin on the door, allowing even spaces on all sides. Attach the hamper bin to the door using eight L-shaped braces, one on each corner, top and bottom, and two evenly spaced on each side. Make certain your screws are not long enough to go all the way through the cabinet door.
