Hand tool for assembling and disassembling roller chain

A method for assembling a work piece using a hand tool having at least one repository having a base, at least one channel, at least one manipulator, and at least one barrier, the work piece having at least a first link, a second link, and a pin, wherein the at least one repository being enclosed in at least one channel housing, the at least one channel housing having a length, the at least one channel housing including the at least one channel, the at least one channel having a second shape and enabling access to the work piece at the base, the at least one channel housing having a first housing end and a second housing end, the first housing end opposing the second housing end, the first housing end including an opposing opening, the method comprising:

• aligning the first link with the second link in the at least one repository;
• locking the aligned first link and the aligned second link in the at least one repository;
• inserting the pin in the at least one channel;
• and
• assembling the work piece by applying pressure, using the at least one manipulator, to the pin, the pressure moving the pin through the at least one channel, the first link, and the second link, the pin being blocked from travel by the at least one barrier.

A method for assembling a work piece, the work piece having at least a first link, a second link, at least one pin, at least one channel accepting the at least one pin, at least one repository having two opposing sides, a base, and an opposing opening, the two opposing sides being shaped to receive the work piece, the method comprising:

• aligning the first link with the second link according to the two opposing sides, the aligned first link and the aligned second link resting between the base and the opposing opening;
• applying pressure by at least one manipulator against the at least one pin, the pressure forcing the at least one pin through the at least one channel, the pressure operably coupling the aligned first link with the aligned second link;
• and
• blocking travel of the at least one pin by at least one door rotatably coupled with the opposing opening, the at least one door including at least one blind aperture, the at least one blind aperture abutting the at least one pin.

A method for assembling and disassembling a work piece using a hand tool including a body divided into a first work station and a second work station, the first work station and the second work station operably coupled by a bridging wall, the first work station including a first operative channel, the second work station including a second operative channel, the first operative channel including a first operative channel first opening and a first operative channel second opening, the second operative channel including a second operative channel first opening and a second operative channel second opening, a second door rotatably simultaneously covering the first operative channel first opening and the second operative channel first opening, a first door rotatably simultaneously covering the first operative channel second opening and the second operative channel second opening, a connector positioned in the bridging wall, the connector operably coupling the second door, the body, and the first door, the connector enabling rotation of the first door and the second door, at least one manipulator having a first end and a second end, the first end having an insert portion resting adjacent to at least one pin, the insert portion being shaped to accommodate the first operative channel first opening and the second operative channel first opening, the second end being configured to move the at least one pin with respect to the work piece, the method comprising:

• engaging the at least one pin with the insert portion at a second channel second opening;
• moving, by one of the at least one manipulator, the at least one pin through the work piece and through the first door;
• engaging the at least one pin with the insert portion at the first operative channel first opening;
• moving, by another of the at least one manipulator, the at least one pin through the first operative channel first opening;
• moving the at least one pin through the first operative channel;
• and
• moving the at least one pin into the work piece and against the first door at the first operative channel second opening in the second work station.
