Abstract: A masking tool includes a body portion; a masking portion supported by the body portion, the masking portion having an engagement surface sized to fit a periphery of the opening; and a retention member extending from the body portion, the retention member being positioned to engage a surface of the recess to retain at least a portion of the body portion within the recess and to maintain the engagement surface of the masking portion against the periphery of the opening.

Abstract: Fastener alignment tools and methods of utilizing the same are disclosed herein. The fastener alignment tools are configured to operatively engage a plurality of fasteners with a corresponding plurality of fastening locations and include a gripping region and an alignment tool body. The alignment tool body defines a plurality of fastener-receiving regions. Each fastener-receiving region includes a fastener receptacle, which is configured to receive a corresponding fastener in a received orientation relative to the alignment tool body, and a fastener retention structure, which is configured to retain the corresponding fastener within the fastener-receiving region at a retained orientation relative to the alignment tool body.

Abstract: Drill guides for right angle drills include an elongate base, a fore guide, a fore mount, an aft guide, and an aft mount. The fore mount and the aft mount are configured to be operatively coupled to a right angle drill, and the fore guide and the aft guide are configured to permit selective translation of the right angle drill toward and away from the base.

Abstract: A modular system that provides multiple support surfaces for a large heavy object and enables movement of that object with no friction (e.g., on a cushion of air). Each module has an object support surface and a bearing that enables the modules and the heavy object being supported thereby to be moved across a floor with no friction. Each module restrains a portion of the object on top within a frame that opens to allow the supported portion of the object to move off the support surface of the module and onto a stationary object support structure (e.g., a milling machine bed), using a cushion of air at an elevated height from the floor equal to that of the top surface of each module. The modules can be used independently or locked together to move a very large and heavy object or can be used to build a type of bridge which the air bearings underneath the object can cross.

Abstract: An apparatus for comprises a base, a wall, and an opening in the wall. The base has a first end, a second end, and a channel system. The channel system is located closer to the first end than the second end of the base. The wall extends from a side of the base to partially enclose the channel system. The opening in the wall is located closer to the second end than the first end. The shape of the wall is capable of retaining a gas introduced through the channel system in a welding location and causing the gas to move away from the channel system and through the opening in the wall.
