Abstract: A rotary shaper tool for use in conjunction with a power tool used to rotate the shaper tool in which a cutter panel is formed about a cylindrical framework. The cutter panel is formed with rows or sets of cutter teeth and an array of vent holes. Chips formed by the engagement of the spinning cutter panel with a wooden workpiece pass to the interior of the shaper tool and are ejected from the vent holes remote from the area of engagement.

Abstract: A slide assembly for a drawer to be received in a frame has a drawer rail formed to include a rigid stop for attachment to the drawer, a frame rail for attachment to the frame, a bearing for receipt in the frame rail and for receiving the drawer rail slidably therein. The bearing includes a flexible stop which limits outward movement of the drawer rail by engaging the rigid stop when the flexible stop is in a first position and permits outward movement of the drawer rail when in a second deformed position.

Abstract: A slide assembly for a drawer to be received in a frame includes a channel formed to include a detent, a slide member having a tab, and a carriage disposed within the channel for longitudinal movement therein. The carriage includes a flexible finger and a stop configured to contact the detent to limit travel of the carriage relative to the channel. The slide member is configured to be longitudinally moveably received within the carriage and the flexible finger limits the outward travel of the slide member by contacting the tab when the slide member is received within the carriage.

Abstract: The present invention is a backing plate for an acetabular reamer assembly that allows for the attachment of a reamer driver. The acetabular reamer assembly comprises a cutting cup and backing plate, the cutting cup having an external surface with cutting teeth formed therein and having an internal surface, the cutting cup terminating in a peripheral edge. The rigid backing plate has a planar surface which terminates in an outer circumferential edge, the outer circumferential edge being coupled to the peripheral bottom edge of the cutting cup, the rigid plate also having an internal edge profile. The internal edge profile of the rigid backing plate has at least two finger elements protruding from the outer circumferential edge thereof towards a central vertical axis drawn perpendicular to the planar surface of the plate. Further, the finger elements of the backing plate form a holding opening for a reamer driver.

Abstract: A method is shown for manufacturing a bone saw blades from a metal blanks by using an electric discharge machining process. Plural stacks of metal blanks are formed and loaded into a jig where the stacks are secured in an angular position. The stacks of metal blanks are subjected to an electric discharge machining process whereby teeth are machined into the peripheral edges of the metal blanks. The positions of the stacks are switched and the electric discharge machining process is repeated.

Abstract: The invention relates to a method for manufacturing a sheet metal tool that is not planar, and the tools made from the method. A sheet metal blank has a predetermined design of etching resistant material applied to one surface to define exposed areas separated by resist areas. A layer of etching resistant material is also applied to a second surface of the metal blank which overlies at least the exposed areas on the first surface of the metal blank. The exposed areas on the first surface are then subjected to etchant applied from the first surface of the metal blank through the exposed areas to form a tooth shape with a cutting edge. The formed cutting edge terminates in a sharpened surface in the second surface, protected by the layer of the etching resistant material on the second surface of the metal blank.

Abstract: A method is shown for manufacturing a sheet metal tool from a metal blank in which a predetermined pattern of etching resistant material is applied to the back surface of the metal blank to define exposed areas separated by resist areas. A layer of etching resistant material is also applied to the front surface of the metal blank which overlies at least the exposed areas on the back surface of the metal blank. The exposed areas on the back surface are then subjected to etching treatment through the exposed areas to form a tooth shape with a cutting edge. The etching treatment is applied solely from the back surface of the metal blank, whereby the cutting edge is so formed terminate in sharpened surfaces in the plane of the front surface, protected by the layer of the etching resistant material on the front surface of the metal blank.
