A temporary clamping fastener is disclosed, and includes a bushing having an inner cavity, an upper open end, and a lower open end. The temporary clamping fastener also includes a pull shaft having an elongated body and a slot extending through the elongated body. A portion of the pull shaft is disposed in the inner cavity of the bushing, and the pull shaft is configured to linearly translate relative to the bushing. The temporary clamping fastener also includes a clamp blade disposed within the slot of the pull shaft and rotatable between a stowed position where the clamp blade is housed within the slot and a deployed position and a portion of the clamp blade extends from the slot of the pull shaft to create an engagement surface for through-hole clamping.

A leak detection system configured to be attached on an exterior of a conduit to detect a leak in a non-pressurized conduit. The leak detection system includes a first fluid section and a second fluid section that each includes the same or similar fluid volumes. The first fluid section includes a testing chamber configured be attached to the conduit. With the testing chamber positioned on the conduit, a pressure sensor connected to each of the first and second fluid sections senses a difference in the fluid pressure between the first and second fluid sections to detect a leak.

Disclosed herein is a system for indexing a workpiece. The system comprises a vacuum source and a fixture plate, fluidly coupled with the vacuum source. The system also comprises an indexing stop, coupled to the fixture plate and fluidly coupled with the vacuum source. The indexing stop is actuatable between an extended position and a retracted position relative to the fixture plate. The vacuum source is selectively operable to concurrently apply a suction force to a workpiece supported on the fixture plate to urge the workpiece against the fixture plate and to the indexing stop to actuate the indexing stop from the extended position to the retracted position.

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.
