How to Build a Dog Ramp

Fasten a block to the underside of the lid, ½ inch from one end. This block will serve as a handle for pulling the collapsed ramp out from underneath the bed.

Set the box upside down onto the underside of the lid. Center the box between the sides of the lid and so that the ends sit flush with the ends of the lid. Using a drill/driver, secure a 30-inch piano hinge, knuckle side out, to the side of the box. Screw the hinge to underside of the lid.
