An improved portable work bench includes a structural body, and a platform disposed on and frictionally contacting the structural body. In addition, the platform includes an override mechanism for allowing horizontal movement of the platform along the structural body. Further, the portable work bench may include a plurality of legs for supporting the structural body. The structural body may be tubular and preferably has a trapezoidal cross-section. Such work bench can be used by disposing the platform on the structural body, so that the platform frictionally contacts the structural body. Then the user can mechanically override the static friction between the platform and the structural body and move the platform horizontally along the structural body.

Portable work bench

An improved portable work bench includes a structural body, and a platform disposed on the structural body. In addition, the platform includes a cam mechanism for locking the position of the platform along the structural body. Further, the portable work bench may include a plurality of legs for supporting the structural body. The structural body may be tubular and preferably has a square cross-section. Accordingly, the user need only place the platform in any position along the length of the structural body and move the cam mechanism to lock the platform in place. The cam mechanism may include a cam pivotally attached to the platform near the structural body, so that when the user rotates the cam, the cam contacts the structural body, locking the platform. A plate may be disposed between the cam and the structural body. The plate may have a hook portion, which contacts the bottom surface of the structural body.

The scroll saw disclosed herein includes a frame with a worktable for supporting workpieces, first and second blade clamps for clamping a blade therebetween, an oscillating mechanism disposed within the frame, the oscillating mechanism moving the first and second blade clamps in a direction along a substantially vertical axis, wherein one of the first and second blade clamps is selectively shiftable so that the blade is shifted to a selected angle from the vertical axis. Preferably, a cam is used to move one of the blade clamps.
