Abstract: An apparatus for use in cutting a mortice pocket in a leading edge of a door in-situ, the apparatus comprising: at least one elongate guide means; clamping means for clamping the elongate guide means to a door or other workpiece; a drill guide means mounted on the elongate guide means; and translating means; wherein the drill guide means comprises a bearing block and a saddle member, the saddle member having a bearing block aperture formed therethrough arranged to releasably receive the bearing block therein, the bearing block having a hole therethrough adapted snugly to receive a drill shaft such that the drill shaft is supported, directly or indirectly, by the bearings of the bearing block and is rotatable therein, and wherein at least one of the bearing block aperture and the bearing block is tapered.

Abstract: A saw guide intended for guiding the blade of a saw during cutting of a workpiece (220). The saw guide (10) comprises: a body portion (120) having a basal surface (115) and a guide surface (105) adapted to be positioned on a workpiece (220) to be cut, such that with the basal surface (115) engaging a surface (200) of the workpiece (220), the guide surface (105) extends across the surface to be cut at a forward position of the body portion, such that a cutting member (300) in face to face contact with the guide surface (105) may be guided during cutting of the workpiece (220), and measuring means for measuring a position of the guide surface (105) with respect to a workpiece (220) such that, in use, the position of the guide surface (105) may be monitored by reference to said measuring means, during a cutting operation of the workpiece (220). The saw guide enables a cut to be made with continual reference to the measuring means.
