ABSTRACT:
A radial arm saw features light weight, portability and simplicity of construction. A standard supports a one-piece radial arm that comprises a pair of horizontal, vertically spaced cantilever rails rigidly joined at their outer ends by an integral connecting member. A sliding runner spans the rails and has vertically spaced bearing parts receiving corresponding rails. A vertical spindle on the runner is connected at its lower end to the top of a cage that receives a conventional portable circular saw, thereby suspending the saw unit beneath the rails and above the work surface. The spindle permits the cage to be rotated for either cross-cut or ripping operations, and the radial arm is adjustable in a horizontal plane by a special detent arrangement on the standard that allows the elevation of the saw unit to be varied in any selected radial position.
