A rail shoe assembly for mounting a drilling machine to a rail of a railway track, with the drilling machine including a drill, a cutter, and a support frame with the support frame mounted to the rail, includes a base adapted to be positioned with respect to the rail and adapted to be coupled to the support frame. The rail shoe assembly also includes an adjustable bar coupled to and slideable relative to the base. The adjustable bar has a bottom edge for engagement with the rail. The adjustable bar defines a plurality of position indicators and the base defines a plurality of mounting chambers. At least one of the plurality of position indicators and at least one of the plurality of mounting chambers are alignable at a predetermined position for positioning said base relative to the rail such that the drill and cutter are positioned relative to the rail.

A fixturing device for attaching attached to a work piece and methods of attaching the fixturing device to the work piece. The device may include a body, a base, and an extension. The extension may extend outward from the body and is sized to initially be positioned within an opening in the work piece. The extension may be expandable in size to engage with a backside of the work piece at the opening to secure the device to the work piece. The device further includes an interface for receiving to a tool that performs an operation on the work piece.

A counterbalance system employs one or more springs to support a large motor drill on an upper horizontal work surface, for example on the tops of drill jigs or bushings. The counterbalance system supports the drill above the work surface where the counterbalance system can slide across the work surface to selectively position the drill over a drill bushing through which a drilling operation is to be performed. A user of the drill supported on the counterbalance system can then push downwardly on the drill to compress the spring and perform a drilling operation. On removal of the downward directed force exerted by the user of the drill, the spring pushes the drill upwardly to disengage the drill from the work surface. The user of the counterbalance system can then slide the counterbalance system and the drill across the top of the work surface.

A power tool stand includes a base and a projecting frame connected to the base. The power tool stand also comprises a power tool carriage moveably mounted on the projecting frame. The power tool stand further comprises a tool interface mounted on the power tool carriage arranged to secure a removeable power tool. The power tool carriage comprises at least one duct having a duct inlet in fluid communication with a duct outlet.

Embodiments generally relate to an alignment device to assist in drilling or reaming an opening in a structure. The device comprises: a base element, the base element having at least one first fixation element to allow fixation of the device relative to the structure; a positioning element coupled to the base element, wherein a position of the positioning element relative to the base element is adjustable; an alignment element mounted to the positioning element and rotatable in at least two dimensions to allow precise alignment for a drilling or reaming tool with a drilling or reaming site on the structure; at least one second fixation element to allow fixation of the positioning element relative to the base element; and at least one third fixation element to allow fixation of the alignment element relative to the positioning element.

A drill press comprises a hollow pillar with a base, a holder for a drill slidably mounted on the pillar and a clamp integral to the pillar for clamping the base to a work piece so that the drill is guided to the work piece. The clamp is a G clamp with a jaw held by an arm which engages a screw thread shaft housed in the pillar so that rotating the shaft raises and lowers the arm and the jaw.

A power tool stand includes a base and a frame connected to the base. A power tool carriage is mounted on the frame. A tool interface is mounted on the power tool carriage and arranged to secure a removeable power tool. The power tool carriage comprises at least one duct configured to convey a fluid. The tool interface includes a moveable fluid connector in fluid communication with the at least one duct wherein the moveable fluid connector is configured to move from a first position to a second position.

A power tool stand comprises a base; a projecting frame connected to the base; and a power tool carriage moveably mounted on the projecting frame. The power tool carriage comprises a first interface arranged to electrically connect with a removeable power tool and a second interface in electrical connection with the first interface and arranged to electrically connect with a removeable battery.
