Abstract: The power trowel of this invention has a chassis comprising a gear box and a prime mover and has a plurality of blades which engage a surface to be finished and which are driven by the prime mover, through the gear box, for substantially edgewise rotation about a vertical axis. An elongated handle for controlling movements of the machine across the surface has a pivotal connection to the chassis to be swingable up and down, but has an upper limit of such motion from which it is swingable downwardly.

The center of gravity of the chassis is spaced forward of the vertical axis. Control of machine movements is minimally influenced by machine vibration, and is therefore more precise and less fatiguing.

Abstract: Disclosed is a method and fixture for applying a thin layer of polymer material to a piece of wavy sheet metal, so that the layer may function as a backer during electron beam drilling. The sheet is drawn to the smooth surface of a fixture using a vacuum, and polymer is flowed across the surface using a curved leveling board, which produces a generally uniform thickness molding. The edges of the backer are molded with a bevel edge by shaped side rails, to provide a relief around the edge of the backer layer. Thus a raised up portion usually occuring at the edge rail will not interfere with the precise spacing which the backer is intended to produce between the sheet and the workpiece holder during electron beam drilling.
