A tool and method for replacing or installing components in a confined, interior space of a plumbing faucet valve assembly. The tool comprises a hollow body having a first end and a second end. The first end has an inner diameter and an outer diameter, and the second end has an inner diameter and an outer diameter, wherein the outer diameter of the first end is smaller than the outer diameter of the second end, thus forming a lip or flange proximal the first end for a purpose of engaging a plumbing faucet component for ease of installation during repair or replacement of the component in a plumbing faucet. The tool is manipulated by simply sliding it over the shaft of a screwdriver or other implement during operation. The tool facilitates proper alignment and installation of the replacement components into the confined interior space of the faucet.

A method and tool assembly (10) for unloading and reloading spring energy from a torsion bar (11) in a torsion bar suspension system of a motor vehicle. The tool assembly (10) includes a generally C-shaped body (14) having a screw shall (24) threaded through a boss (22) in a lower section (18) thereof. An anti-rotation stem (38) includes a knurled flat face (40) which increases versatility of the tool assembly (10) by enabling anti-slip operation with various vehicle types. A counter-torque tool perch (46) extends from the lower section (18) of the tool body (14) for applying a counter-rotational torque to the body (14) during use of the tool assembly (10).

A device to apply a rotational force to a spring of a rollup or overhead garage door counterbalancing mechanism. The device has a rotatable driven member mounted in a housing. The housing and the driven member have slots with an open end adapted to receive the shaft of the overhead garage door counterbalancing mechanism. A coupling member is configured to mount to the driven member and connect the driven member to the winding cone of a garage door spring to apply rotational force to the spring. The housing with the driven member may be connected to the body of an existing power tool in place of the original tool head, or, the housing may be permanently combined with a motor and transmission to provide a special purpose tool.

A device for extracting a deeply embedded helical coil is provided. The device includes a shaft, the shaft comprising a proximal end and a distal end; and a blade coupled to the distal end of the shaft, wherein the blade is configured to traverse into a mounting hole to engage the deeply embedded helical coil free of contact with a side of the mounting hole and wherein the deeply embedded helical coil is at least three to five thread pitches below a surface of the mounting hole.

A mainspring disassembly tool for M1911-style semiautomatic pistol mainspring housings is disclosed, allowing the compression of the mainspring (a.k.a. hammer spring) to be easily and safely released and the retaining pin removed without the use of a bench vise. The mainspring disassembly tool is compact, and can be used with one hand, leaving the other hand free to remove or insert the retaining pin, making it suitable for use in the field. Disassembly, removal, installation, and reassembly of the mainspring from the mainspring housing can all be accomplished readily with only two hands.

Torsion spring tensioning tool (100) for tensioning a torsion spring of a counterbalancing mechanism of an overhead door, wherein the torsion spring tensioning tool (100) comprises a housing (80), a gear wheel arrangement (20) adapted to be mounted on a shaft of the counterbalancing mechanism, said gear wheel arrangement (20) comprising a gear wheel (21) rotatably arranged in the housing (80), the torsion spring tensioning tool (100) further comprising a gear mechanism (54) coupled to the gear wheel (21) for rotating said gear wheel (21). The gear wheel arrangement (20) comprises a first and second engaging arrangement (32, 60) arranged to be fixed relative to the gear wheel (21).
