A firearm maintenance aid can include a firearm vise and a firearm support device. Firearm vise can include vise jaws, a threaded rod connecting vise jaws together, and jaw pin holes in each jaw, the holes extending from an outer surface of a jaw through to an inner surface of each jaw, wherein the holes in the first jaw align with the holes in the second jaw. Firearm support device can include a clamping portion and a supporting portion. The clamping portion can be clamped between the jaws of the firearm vise, can include two parallel clamping faces, and can define vise pin holes that align with the jaw pin holes. The supporting portion can be located opposite the clamping portion and can include a cylindrical shaft. Vise pins can be received by the jaw pin holes and vise pin holes to fixedly connect the support device to the vise.

Add-on components for a workpiece holder or vise, including a pair of jaws. A work piece lock element is moveable and lockable along a top surface of one of the pair of jaws. The work piece lock element can be or include a positive lock, such as including a threaded element, a rounded or spherical element, and/or a spring loaded ball. In embodiments, a row of detents is disposed in one of the jaws, and each of the detents is configured to receive the positive lock in one position. An adjustable side extension can be included for laterally securing workpieces in the holder. A pair of clips, each attached to a side of one of the pair of jaws, can be used to secure a parallel against the one of the pair of jaws. Parallel keepers can be used to reduce lateral displacement upon tightening the jaws.

Implementations of a clamp finger may include a first portion including at least one tip configured to clamp a substrate against an anvil during a bonding operation; and a second portion including a first opening therethrough configured to permit coupling of the second portion with a clamping bridge. The first portion may be slidably coupled with the second portion through a rail and the first portion may include an opening therethrough configured to receive a screw that fixedly couples the at least one tip of the first portion at a desired position relative to the second portion.

An improved vise adapter for use with existing industrial single stage vises. A rear fixed jaw adapter block is mounted on the rear fixed jaw of the vise, a front floating jaw adapter block is mounted on the front floating jaw of the vise, and a middle floating jaw is slidingly mounted therebetween on two pairs of guide shafts extending out from the rear fixed jaw adapter block. The front floating jaw adapter block also is slidingly mounted on the guide shafts. As a linear clamping force is applied in the direction of the fixed jaw of the vise, the adapter holds two workpieces instead of a single workpiece.

Disclosed are vise embodiments designed to lower manufacturing cost and work well in an automated CNC milling production environment. The disclosed embodiments include rigid vises having high clamp force and low internal friction. The embodiments include features for resisting the ingress of metal chips into sensitive moving parts through the use of commonly available seals and the flow of CNC coolant to flush metal chips away from the vise.

A leveling system for a clamping device can include a base having a top, a bottom, and a plurality of sides; and a leveling knob positioned on one of the plurality of sides of the base and comprising a spring, a pin, and a knob connected at an outer end of the shaft. The spring can be compressible when the knob is pulled away from the base. In a locked configuration, the leveling knob can be at a neutral angle and in a home position with the pin positioned within the base. The pin can be removable from the base when the spring is compressed. The leveling knob can be twistable in at least one of clockwise and counterclockwise rotations when the pin is removed from the base.

A modular tray system can include a tray assembly and a ball head joint. The tray assembly can have a main tray and at least one liner tray nested in an interior of the main tray. The ball head joint can have a ball head and a stem, wherein the stem connects to the tray assembly. The modular tray system can include at least one magnet located between the main tray and the at least one liner tray. The at least one liner tray can have a plurality of compartments, wherein at least one magnet is located underneath each of the plurality of compartments. The at least one liner tray can be comprised of a first liner tray having a single compartment and a second liner have multiple compartments. A cover can secure onto the tray assembly to retain any pieces/liquids stored in the at least one liner tray.
