An assembly which provides a rotating work surface extension. The assembly may be attached or fixed to an existing work space platform. An assembly comprising interchangeable rotating work surface extensions is disclosed, along with a system comprising such an assembly and a method of positioning a workpiece utilizing such an assembly.

A carpentry block is provided to support a remote end of a board or work piece to be cut with a table saw or chop saw. The block has a triangular body which can be positioned on any base to define three different heights to support the remote work piece end. The block can also be positioned on the one end to define a fourth height for work piece support. An extension member can be added to the block to provide additional heights with the block, the outer end of the work piece is level with the saw table, thereby assuring an accurate cut of the work piece by the saw blade.

A magazine for storing shaft-shaped workpieces includes at least one receiving body (12) with at least one receiving hole (15) for insertion of an end section (11a) of a shaft-shaped workpiece (11). The end section (11a) that has been inserted in a receiving hole (15)viewed along the longitudinal axis (L) of the workpiece (11)is shorter, and, in particular, shorter by the factors three to five, than the remaining section of the workpiece (11) that adjoins the end section (11a). The receiving body (12) is configured in such a manner that, in operating position of the magazine (10), the center axes (M) of the at least one receiving hole (15) and the vertical (V) subtend a first angle of inclination (). As a result of this, it is achieved that the workpieces (11) tilt in a defined tilt direction (K) and do not hit each other.

Systems and methods for a stud plate connector are disclosed. The system can include a base plate having a first cam slot and a second cam slot, where the second cam slot is approximately a mirror image of the first cam slot. The system can include a first upper cam-follower located within the first cam slot. The system can include a second upper cam-follower located within the second cam slot, where the first and second cam-followers hold opposite sides of a first lumber and move the first lumber to contact a second lumber. The system can include a first lower gripper and a second lower gripper for holding the second lumber in a perpendicular direction with respect to the first lumber. The system can include a bonding device located before to the first and second lumber, where the bonding device bonds the first and second lumber together

An apparatus includes a chuck configured to hold a wafer and a tilt plate disposed beneath the chuck and adjustably connected to the chuck by a pair of upper screws and a pair of lower screws separately arranged in opposite corners of the chuck. Screw heads of the pair of upper screws rest against a top surface of the chuck, such that clockwise rotation of one of the upper screws pushes a corresponding corner of the chuck toward the tilt plate. Screw heads of the pair of lower screws rest against a bottom surface of the chuck, such that counter-clockwise rotation of one of the lower screws pushes a corresponding corner of the chuck away from the tilt plate.

A precision tripod motion system is provided. The tripod motion system in one example includes a bottom plate including three spaced-apart bottom single-degree-of-freedom hinges, a top plate including three spaced-apart top three-degrees-of-freedom (TDOF) joints, wherein the top plate is configured to receive a workpiece. Each linear actuator of three linear actuators is coupled to an associated SDOF hinge of the bottom plate and coupled to an associated TDOF joint of the top plate. Each linear actuator is configured to change length over a linear actuation span and configured to return the top plate to a predetermined set position after the top plate is displaced by an external force Each linear actuator includes a ball coupled to the associated three TDOF joint and a positioning actuator configured to move the ball to the predetermined set position prior to the return of the top plate to the predetermined set position.

Disclosed is a configurable table that uses configurable mounting pieces to mount a work piece on the configurable table at a predetermined location. The configurable table includes a fixed portion of a mounting clamp that can engage a rotatable portion of a mounting clamp on a positioner or other device. The positioner can then rotate the configurable table and work piece to various orientations for performing horizontal welds, using robotic welders, as well as machining and cutting. The configurable table can also be used for initial fabrication, cutting, or working, which eliminates the need for separate fabrication and finish welding tables.
