Abstract: A woodworking gauge for use with a boring, drilling or cutting mechanism having a support surface and a cutting implement disposed on and extending through the support surface includes a pair of alignment blocks joined by a pair of connecting rods. The rods are slidably positioned within bores extending through each of the alignment blocks and can be fixed with regard to the alignment blocks by clamps disposed on the blocks. One alignment block includes a channel lock that is engaged with the support surface to secure the alignment block in a stationary position on the support surface. The remaining alignment block includes a cutting implement-engaging insert to be positioned against the boring, drilling or cutting blade. The position of the connecting rods extending past the alignment block engaged with the blade enables a cutting fence to be positioned to achieve the desired depth cut within the material workpiece.

Abstract: A magnetic clamping device is provided that includes a housing in which a number of magnets are disposed. A magnetizable core extends through the housing between the magnets and is movable with respect to the housing and the magnets. The core can be moved using a suitable mechanism disposed on the housing between an extended position where the core is positioned in contact with the support surface and a retracted position where the core is spaced from the support surface. The position of the core relative to the housing and the support surface adjusts the magnetic holding force transmitted from the magnets through the core to attract and hold the core on the support surface.

Abstract: An adjustable fence can be easily and securely attached to the support surface of a boring, drilling or cutting device. The fence includes a base that is releasably attachable to the support surface of the boring, drilling or cutting device adjacent boring, drilling or cutting mechanism. The base includes a pair of brackets located at each end of the base that rotatably support a barrier therebetween. The barrier or fence angle includes a clamping mechanism engageable with each of the brackets on the base in order to releasably secure the fence in the desired position relative to the base. The base also includes a number of stops moveably secured to the fence that can be positioned on the fence angle at the desired location to function as a stop for the movement of the work piece relative to the fence while acted on by the boring, drilling or cutting mechanism.
