Claim:
An apparatus ( 10 ) for making a sloped surface having a point of lowest elevation and a point of highest elevation, the apparatus comprising: a guide member ( 36 ) positioned about a periphery of a surface, the guide member ( 36 ) having a top surface; and a leveling member ( 12 , 14 ) comprising a first leveling member ( 12 ) and a second leveling member ( 14 ) slidingly mounted to each other in a telescoping arrangement such that the leveling member ( 12 , 14 ) has a selectively adjustable length, one end of the first leveling member ( 12 ) positioned at the point of lowest elevation of the surface, and one end of the second leveling member ( 14 ) resting on the top surface of the guide member ( 36 ) to define a point of highest elevation of the surface; and wherein the leveling member ( 12 , 14 ) varies a slope of the surface ( 44 ) depending on a distance between the point of lowest elevation ( 54 ) and the point of highest elevation as the leveling member ( 12 ) travels along the top surface of the guide member ( 36 ).
