Abstract: An expandable mandrel for holding a workpiece, including a mandrel body having an interior surface and an exterior surface. The interior surface defines at least first and second interior regions separated by a transition surface, the first region having a cross sectional area greater than a cross-sectional area of the second region. A plurality of slots extend between the interior surface and the exterior surface. A slave actuator having a bearing surface is at least partially disposed in the first region, and a master actuator is provided for urging the bearing surface against the transition surface to expand the mandrel against the workpiece.

Abstract: A device used to hold/support a target or multiple targets in the ground for the purpose of target shooting with firearms, air guns, and the like. This target supporting device allows any size or thickness material typically used for target shooting to be securely embedded into the ground, regardless of the slope of the ground to the line of fire. Additionally, any type of card, board, or sign can be supported in the ground to post information such as yard sales, keep off the grass notices, trail maintenance, etc.

Abstract: A removable ice cleat for an outer frame member of a snowshoe provides traction for snow packed and icy conditions. For looser conditions including powdery snow, the ice cleats are quickly removable thus making the snowshoe versatile for all weather conditions. The ice cleat is attached using a metal band clamp that is tightened by a screwdriver or nut driver thereby making deployment of the ice cleats possible while outdoors. The ice cleat has an ice pick that is clamped by the band to the bottom of the outer frame member of the snowshoe. Several ice picks can be clamped in this manner. The picks have legs that extend downwardly and outwardly from a mid portion thereof to pointed ends having a generally triangular shaped penetrating portion that maintains good penetrability even as the pointed end becomes dull.
