Abstract: A soft synthetic resin, such as polyurethane, body is molded onto a metallic steering wheel frame except for a part thereof intended for installation of the steering wheel onto a column shaft and a soft burr formed on the resultant covered steering wheel along the parting line of the mold is removed by refrigerating the steering wheel to make the burr hard and fragile and then removing the burr by shot blast treatment, whereafter the steering wheel is heat dried to eliminate water from the atmosphere condensing on the exposed metallic installation part of the steering wheel and prevent resulting corrosion of that part.

Abstract: The invention provides a manually operable wet sander which uses standard strips or rolls of sandpaper. The sander has a one-piece generally solid body containing a means for removably securing the sandpaper to the sander without piercing the sandpaper. Conduits contained within the sander body regulate the flow of water, or other suitable liquid, from an external pressurized source to a plurality of liquid outlets along both sides of the sander. The water then flows past the edges of the sandpaper strip and onto the surface being sanded. Edge strips are preferably added to direct the water when the surface being worked is vertical or near-vertical or overhanging.

Abstract: An apparatus for abrasive machining has an annular support (1) and a faceplate (5) which is operatively connected to a drive and is mounted on a thrust bearing (2) for rotation in a radial bearing (8). According to the invention, the faceplate (5) has a coaxial bushing (7) journalled in the radial bearing (8), and the faceplate (5) and the annular support (1) are elastically coupled to each other by means of an axle (9) extending through the bushing (7) and biased by a spring in the direction of preload in the thrust bearing (2), the faceplate (5) being connected to the axle (9) for rotation relative thereto by an auxiliary thrust bearing (12) and having on the outer cylindrical periphery thereof a driven member of the drive, a plane (17) drawn through the middle of width of the driven member (16) of the drive extending through a plane (18) drawn substantially through the middle of width of the radial bearing (8 ).
