Abstract:
1. A method of fabricating a runner for mounting on the underside of a snowmobile ski, comprising: preparing a single generally planar sheet of metal material having a predetermined hardness, a generally uniform thickness and upper and lower faces; separating a shaped workpiece from the planar sheet; bending predetermined runner portion side regions of the shaped workpiece out of the plane of the workpiece to extend the runner portions downwardly from laterally opposite sides of a central longitudinally extending base portion of the workpiece and defining a generally U-shaped channel on an underside of the workpiece; forming lower free edges of said runner portions with a notch recessed into said runner portions from said lower free edges; securing a hardened wear strip having a hardness greater than said predetermined hardness of said metal material in each of the notches, and, forming mounting portions on the base portion that project upwardly from a top side surface of the base portion and which do not extend into said U-shaped channel.
