A cam lock connected with a fence assembly includes a handle portion, a top carrier and a bottom carrier connected by a threaded shaft. The handle portion and top carrier are positioned above the fence assembly and a work table or surface; wherein the bottom carrier is positioned below the fence assembly and work table or surface. The top carrier and bottom carrier both have a pair of alignment arms with a space positioned therebetween, the alignment arms of the top carrier nest with the alignment arms of the bottom carrier. The handle portion and top carrier both have cam surfaces that engage one another such that when the handle portion is rotated around the axis of the threaded shaft the handle portion is raised or lowered thereby raising or lowering the bottom carrier, thereby locking or unlocking the fence assembly in a quick, durable, easy and accurate manner.

A mechanical self-centring gear extractor device allows the use of a hydraulic cylinder to provide the extraction force, while having self-centring that prevents the accidental opening of the claws, increasing safety during extraction. The extractor includes a first spindle and pulling claws articulated and indirectly coupled to the first spindle, so they can move along it while being supported by it; including a centring device for the claws consisting of connecting rods articulated at one of their ends to intermediate regions of the claws and at the opposite end to a support whose position can be adjusted coaxially along the upper part of the first spindle, including a second spindle coaxial with the first spindle and independent of it in rotation and secured to it in stroke, and including an external thread to thread a handle joined in stroke and independent in rotation of that position adjustable support.

A single-hand operable portable hand-held saw, including a handle portion with a motor. The motor is operably connected to one or more drive gears positioned on an interior side of a protective cover. One or more idle gears are positioned on an interior side of the protective cover. The idle gears and the drive gears are operatively coupled with and rotatably engaged with an annular saw blade. A throat opening in the protective cover is positioned adjacent a stop guide for stabilizing the saw against a material during cutting operations.

The invention allows for alignment perpendicular to a track engaged by a securing nut. An opposing tooth key type aligner has two functions: keeps the second track perpendicular to the first track and allows the securing nut to always be correctly oriented to engage with the track. A bolt clamps the securing nut to the track to lock the position of the invention. A second axis perpendicular to the lower track is created with a second track. A bolt connected to a coupler nut engages with the middle track to create a third axis perpendicular to both previous axes. A washer provides a neutral bearing surface between the coupler nut and second track. An elevation bolt sets the vertical position of the object to be mounted. A bolt can be used to fasten an object to the end of the elevation bolt.
