A device for positioning and stabilizing individual teeth during laboratory research for cutting or crown removal. The device includes an adjustable bar having a first side wall and a second side wall located opposite the first side wall. An adjustment mechanism is located on the second side wall. The adjustment mechanism is adjustable in a direction perpendicular to the first side wall. A plate is located between the first side wall and the second side wall. A height adjusting screw is located at the bottom of the adjustable bar moving the plate in a vertical direction adjusting the height of the plate. A first tilt screw is located at an opposite end of the adjustable bar as a second tilt screw allowing for rotation of the adjustable bar around the first and second tilt screws.

An alignment tool for use in a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a clamp portion, a component engagement portion and an arm portion that extends between the clamp portion and the component engagement portion. The clamp portion establishes a fixed datum surface for positioning a component within the gas turbine engine.

Adapters are described which enable a wide array of tools to be secured and/or mounted in a chain pipe vise. Also described are methods of using adapters with chain pipe vises in order to stably mount tools in the chain pipe vise.

A machining tool assembly is provided for machining a blank to form a firearm lower receiver. The assembly includes a pair of side plates positionable on opposed sides of the blank to capture the blank therebetween. A template plate having a template aperture is adapted to be removeably attachable to the side plates. The template aperture is aligned with a top surface of the blank and is adapted for machining a cavity within the blank having a peripheral contour complimentary to a peripheral contour of the template aperture. A centering mechanism is adapted to be removeably attachable to the template plate, with the centering mechanism including an opening aligned with a corresponding void formed on the blank to align the blank with the template plate.

A line mount includes a treatment machine having a housing and one or more magnets or ferromagnetic elements mounted thereon, a line holder having at least one complementary one of magnets and ferromagnetic elements such as to cause the line holder to be attachable magnetically to the housing. The one or more magnets or ferromagnetic elements being numbered and arranged to permit the line holder to be supported thereby in multiple positions and orientations relative to the housing.

Disclosed generally is a quick change face plate for a vise.

A T-Nut for use in a machine tool having a tooling plate with an inverted T-shaped channel. The T-Nut comprises a central body having oppositely inclined faces each including an opening forming a cavity extending through the central body, and first and second wedges in slideable communication with the central body inclined faces. Each of the wedges have wings extending laterally beyond the central body to engage upper surfaces of the channel lower wide portion and include a clearance hole extending through a length of the wedge. A rotatable actuation member abuts the first wedge at an end opposite the first wedge mating surface and is internally threaded for a distance from one end thereof. An externally threaded cylindrical shaft is engaged with the internal threads of the actuation member and extends through the first and second wedge clearance holes, the shaft being secured to and non-rotatable with the second wedge. In operation, when tooling is secured to the top surface of the central body and the actuation member is rotated, the first and second wedges are slideably moved symmetrically along the central body inclined faces until the first and second wedge wings engage upper surfaces of the channel lower wide portion while the tooling is simultaneously urged in the direction of the tooling plate until the tooling mounting surface bears against the tooling plate top surface, thereby removably securing the tooling to the tooling plate.

A hydraulic fluid actuated lathe tool mounting expander assembly incorporating a block having a base, an inner end, an outer end, a compression end, and a compression face; a first cylindrical void extending into the block, the first cylindrical void having a floor and opening at the block's compression face; a second cylindrical void extending into the block, the second cylindrical void having a floor and opening at the block's outer end; first and second pistons respectively slidably mounted within the first and second cylindrical voids; a conduit extending between the first and second cylindrical voids, the conduit being adapted for conveying the hydraulic fluid from the second cylindrical void to the first cylindrical void; and a jack screw actuator connected operatively to the block for driving the second piston against the hydraulic fluid for upwardly driving the first piston.
