«»
Mark the tipping point of the teeter-totter at 5 feet along a 12-by-8-inch laminated shelving board. Positioning this fulcrum away from the entry side of the teeter-totter will slow the drop rate once the dog crosses it. Mark two lines 2 inches from either side of the fulcrum. Mark each outside line at 3 and 9 inches from the edge.
