A method and apparatus for automated engagement of a fitting coupled to a structure. A first member of a first engagement device is moved relative to a base in a first direction substantially parallel to an x-axis such that a tapered end portion of the first member passes through a hole in the fitting and moves towards a channel within a second member of a second engagement device. The tapered end portion of the first member is secured within the channel of the second member to thereby engage the fitting between the first engagement device and the second engagement device.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.

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.

A tool or hinge positioning jig for creating hinge mortises including a hinge jaw having an hinge jaw first portion opposite and substantially parallel to an hinge jaw second portion, and an exterior first surface facing opposite an exterior second surface wherein at least one of the exterior first surface or the exterior second surface is laterally adjustably coupled to the hinge jaw, and wherein the hinge jaw first portion and hinge jaw second portion are capable of being aligned with first and second hinge edges, respectively, and the exterior first surface and exterior second surface are capable of being aligned with first and second workpiece edges, respectively.

The inventive working spindle comprises a spindle housing and a spindle shaft with axial positioning surface and axial contact surface by which the correct axial position of each fitting provided spindle shaft in the spindle housing is obtained. For torque-proof holding of the spindle shaft in the spindle housing, preferably with stationary motor, a braking unit is provided that comprises a radial outer part that is coupled with the spindle housing in a torque-proof manner and a radial inner part that is coupled with the spindle shaft in a torque-proof manner. The largest outer diameter of the peripheral surface of the inner part is smaller than the narrowest location of the through-opening of the spindle housing between the braking unit and the tool side end of the spindle housing. For this reason the spindle shaft can be readily removed from the spindle housing without disassembly measures of the braking unit, if required, and can be reinserted in reverse route. The inventive working spindle is simply constructed and can be versatilely used. Concurrently it is remarkably easy to maintain.
