A fence assembly of a table saw includes rear and front sliding members on two rails of a table respectively, the rear sliding member having three top projections, the front sliding member having three forward projections, a transverse member interconnecting the sliding members, and a spring biased workpiece guide bar on the transverse member. The workpiece guide bar includes a front locking element for locking the front sliding member, a rear locking element for locking the rear sliding member, the rear locking element having a recess for receipt of the top projection, and a spring biased lever pivotably secured to a front end of the workpiece guide bar. A latch of the lever can be engaged with a protuberance of the front locking element to lock the front locking element or disengaged from the protuberance to unlock same. The lever includes a wedge for locking the front sliding member.

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.

A machining fixture configured to secure a blank part having part inner and outer circumferential surfaces, a part first axial face opposing a part second axial face, and at least two threaded part openings extending inwardly from the part second axial face and toward the first axial face. The machining fixture includes an annular body sized to be disposable upon a pallet of a machine table and has an upper surface including a substantially flat annular surface section, opposing lower surface and at least two through-holes extending between the upper and lower surfaces. At least two fasteners are disposed at least partially within a separate one of the at least two through-holes such that the at least two fasteners project upwardly from the upper surface, and the at least two fasteners are configured to threadedly engage a separate one of the at least two part openings to removably clamp the part second face against the body flat surface section.
