Abstract: A finger joint cutting tool includes unitary finger joint cutter bits. Each cutter bit has a unitary body to provide several integrally formed finger cutting teeth for finger jointing wood materials. Preferably the body is formed by an electrical discharge machine (EDM) process to provide the cutting teeth without any pinchpoints between teeth. The cutter bit therefore does not include several separate stacked knives to provide the cutting teeth. The finger joint cutting tool includes a head having a predetermined axis of rotation. The head has a plurality of locating surfaces spaced radially about the head which receive the finger joint cutter bits at a constant diameter. Each cutter bit is unitary and has a planar cutting face capable of being sharpened. The cutting face includes a plurality cutting teeth having linear fingering edges extending radially between adjacent base and tip edges. Each of the base edges are located at the same radius relative to the axis.

Abstract: A multi-faceted T-slot cylinder for a cutterhead is mounted to a wood lathe arbor using set screws installed in tapped holes which are provided near opposite ends of the cylinder in diametrically opposite faces of the cylinder (rather than in the same face, as is conventional). Static balancing of the cylinder is thereby improved. For fine-tuning, a dynamic balancing collar is mounted on the arbor near the cylinder. This collar has a plurality of tapped holes provided radially therethrough around its circumference. As the arbor is turned slowly, if measurement shows eccentricity in rotation, the high side is determined and a set screw tightened against the arbor in the respective tapped hole. This dynamic balancing can be done before or after the cutterhead is installed on the arbor, and the dynamic balancer can be used in combination with a wholly conventional T-slot cylinder.

Abstract: A device for fastening a chisel to a rotatable chisel block of a wood working machine by means of a clamping bolt engaging a fastening slot in the chisel block, the shank of said bolt extending through an elongated hole in the chisel and by means of a clamping plate holding the chisel and having a transverse extension supporting set screws which engage a rearwardly diverging safety face of the chisel wherein the transverse extension has safety cams engaging recesses in the fastening slot so that the transverse extension is locked in place in a radial direction.
