An improved portable work bench includes a beam, legs for supporting the beam, and at least one bracket having first and second surfaces for contacting respective first and second sides of the beam, wherein the second surface is movable between a first position contacting the second side of the beam, and a second position not contacting the second side of the beam. A spring biases the second surface towards the first position.

Portable work bench

Various example embodiments are disclosed. According to one example embodiment, a router table may comprise a table top, a mounting can, a sleeve, and an adjustment mechanism. The table top may have an aperture and a plurality of support members; the support members may be configured to support the table top. The mounting can may be attachable to the table top in a vicinity of the aperture. The sleeve may be engaged to the mounting can, and may be configured to receive a router and to position a router bit of the router along an axis extending through the aperture. The adjustment mechanism may be configured to move the sleeve within the mounting can and relative to the table top to thereby move the router along the axis and position the router bit at one of a plurality of positions relative to the table top.

Workpiece support

A scroll saw including an adjustable tensioning mechanism is disclosed. The saw includes a housing having an inner surface and a pivoting arm having a rearward end disposed within an opening in the housing. A first blade clamp is disposed at the forward end of the pivoting arm and secures the upper end of a saw blade. The lower end of the saw blade is secured in a second blade clamp disposed at the forward end of a lower arm. A wedge is disposed within the housing, in contact with the inner surface of the housing. The wedge also is disposed in contact with and translatable along a surface of the pivoting arm. A rod is linked to the wedge at one end and extends through the pivoting arm. The rod includes an upwardly turned arm. A cam having a spiral track is rotatably mounted at the front of the pivoting arm with the upwardly turned arm disposed in the track. Rotation of the cam causes the track to move along the upwardly turned arm, further causing the rod and wedge to move forwardly, with the contact between the wedge and the inner surface causing the wedge and the rearward end of the pivoting arm to pivot downwardly, and the forward end of the pivoting arm to pivot upwardly to increase the tension of the blade.
