Abstract: A bench and frame component for holding individual planks to be used in a sitting bench where fastening an individual plank to the frame can be avoided. The frame is configured to allow a plank to be received in a holding pocket defined by an upper pocket piece and a lower pocket piece. The upper pocket piece may be connected to and removed from the lower pocket piece. The lower pocket piece may include a series of pocket segments and when connected with the upper pocket piece form a series of two-piece holding pockets for receiving a plurality of planks. The frame component is combined with other components and planks to form a bench. The bench may comprise individual bench sections that connect with similar modular sections to form a sectional bench.

Abstract: A grinding system including a pilot bit and a base having teeth extending from the base. The pilot may have a tapered cross-section, threads to control the rate at which it engages an object and a flute to facilitate the removal of material of an object. A method of using the device may include allowing the bit and the base to work together in a manner that the portions of the system engage an object at a similar rate.
