A polishing stand for supporting a slab of solid material comprises a plurality of vertical supports, a horizontal platform attached to the vertical supports, and at least one clamp member attached to the horizontal platform, the clamp member comprising a vertical section that is coupled to the horizontal platform and horizontally adjustable to clamp a slab. A sink installation tool features an elongated connecting rod, a clamp head mounted to a first end of the connecting rod, and a flip foot mounted to a second end of said connecting rod. The flip foot is movable between a first position substantially parallel to the connecting rod, so that the flip foot may be inserted through the drain hole of a sink, and a second a second position where the flip foot is nonparallel to the connecting rod to engage a bottom surface of the sink.
