Abstract: Disclosed is an apparatus, system, and method for precisely placing holes or attaching sub-components to vertical mullions or other workpieces of various shapes and material compositions. The apparatus, in its basic mode of operation, can accurately locate the positions of holes or groupings of holes to be drilled in the workpiece by means of the calibrated positioning, along the workpiece, of a plurality of fixtures affixed to specially-designed drill guide plates. When used in its advanced mode of operation, the fixtures of the apparatus are re-configured and loaded with a plurality of shear blocks or other connectors, and thereupon an operator, by calibrated placement of the fixtures, may simultaneously pinpoint the required fastening location of the shear blocks and sequentially attach specified fasteners through each shear block, directly onto the workpiece.

Abstract: A process is provided for continuously applying a substantially uniform and smooth filler of a water-based filler material to underlying wood substrates. The process comprises introducing the underlying wood substrates into a filler application area. Then, the initial temperature of the outer surface of the underlying wood substrates is determined. Prior to applying the water-based filler material, the initial temperature of said water-based filler material is determined. Prior to applying same to said underlying wood substrates, the initial temperature of the water-based filler material is continuously adjusted, based on the initial temperature of the underlying wood substrate, so that the final temperature of the water-based filler material of the outer surface of the underlying substrate is maintained. The water-based filler material is continuously applied to the outer surface of the underlying wood substrates in the filler application area.
