Abstract: A universal guide for an electric drill includes a transparent elongated L-shaped member with two mutually perpendicular faces. Each face has two parallel long edges and two short edges, and they share a common long edge. For each face, one of the two short edges is a perpendicular edge and the other of the two short edges is an angled edge in which the perpendicular edges are perpendicular to the long edges, and the common edge is formed such that the perpendicular edges are mutually adjacent to each other and the angled edges are mutually adjacent to each other. Magnetic areas are formed on surfaces of each of the faces. Level indicators are attached to each face perpendicular to the common long edge and to the common long edge in a direction perpendicular to the perpendicular level indicators. At least one long edge is ruled and guide lines are marked on the faces in a direction parallel to the long edges.

Abstract: A device and method for facilitating the installation of fascia materials such as tile on bathtub walls, fireplace facings and feature walls includes a support member with arms that extend so as to fit between facing side walls and be self supporting.

Abstract: The present invention discloses apparatus and method for centering the steering wheel of a vehicle prior to alignment of the vehicle wheels using a wheel aligner. A portion of the apparatus is mounted to the vehicle steering wheel for sensing deviation in the position of the steering wheel from a centered position. This portion of the apparatus can be mounted on vehicle steering wheels having different configurations and can wirelessly transmit signals corresponding to the deviations. The apparatus can be used with differently configured steering wheels by virtue of a linked cam assembly in which rotation of either of a pair of cams causes rotation of the other cam in an opposite direction of equal magnitude. In operation, the deviation in the position of the steering wheel from a centered position with a pre-selected tolerance is determined. When the deviation is greater than the pre-selected tolerance, alignment of the vehicle wheels by the wheel aligner is prevented.
