An extendable utility bar includes a substantially straight elongate outer tube defining an axis and having inner and outer ends and an inner cylindrical surface. A substantially straight elongate inner tube has an axis generally coextensive with the axis of the outer tube and has inner and outer ends and an outer cylindrical surface configured and dimensioned to be slidingly engaged at the inner ends within the outer tube in telescoping relationship to move between fully retracted and extended conditions in which the remote ends of the tubes are minimum and maximum distances, respectively, from each other. A first prying member at the remote end of the outer tube and a second prying member at the remote end of the inner tube are provided. A lock selectively locks the inner and outer tubes relative to each other to fix the positions of the prying members at a distance no less than the minimum distance and no greater than the maximum distance. In this way, the length of the utility bar can be increased to provide increased prying leverage and can be decreased to shorten the length of the bar for storage or mobility.

The present invention discloses a workshop unit for use as a grinding center that includes a support frame having a drive motor and a multi-station tool mounted thereto. Particularly, the grinding center may be used for operations including but not limited to grinding, buffing, polishing, sanding, and cleaning. The multi-station tool includes a plurality of rotary tools, a power transfer system, and a rotary tool selecting system. The power transfer system operates through a plurality of pulleys each in communication with at least one rotary tool and the drive motor through a plurality of transmission links. The rotary tool selecting system, which includes one or more control shafts and a clutch system, allows each tool to be selectively and independently operated. The present invention provides a cost and space saving apparatus in which several tools share expensive components and are arranged within one unit to provide more functionality in less space relative to the same tools purchased and operated individually.
