The device includes a bed plate which can be placed on the table of a table saw and held against the rip fence and onto the table top by a block clamped to the rip fence which allows the bed to be moved fore-and-aft upon the table top parallel to the saw balde. A live center and a dead center are provided to hold a work piece therebetween parallel to the saw blade. In one aspect of the invention the work piece can be indexed and engage the saw blade to cut three or more equidistant lengthwise facets thereon. In another aspect these facets can be tapered end to end or from the center to each end by shifting the tail stock towards the blade or by first shifting the tail stock and then the head stock. In a still further aspect, the head stock includes means to rotate the work piece by a source of power so that a tapered cylindrical shape may be cut or dowels may be formed.
A lathe and indexing jig for use on a table saw which includes a planar table having an upper surface and a rotatable saw blade extending therethrough, a rip fence thereon extending parallel to the rotatable saw blade and being selectively moveable and clampable across the table top in direction perpendicular to the plane of rotation of the saw blade;
In combination with a table saw having a planar table with an upper surface thereon, a rotatable saw blade extending therethrough, a rip fence parallel to the plane of rotation of said saw blade, and being selectively moveable and clampable across the table top in a direction perpendicular to the plane of rotation of the said saw blade, a substantially rectangular bed plate, hold down means cooperating between said bed plate and the associated rip fence for mounting said bed plate upon the upper surface of the saw table for manual fore-and-aft movement thereon parallel to the plane of rotation of said saw blade and to one side thereof, a tail stock assembly adjustably mounted towards one end of said bed plate for selective and lockable fore-and-aft movement parallel to the plane of rotation of the saw blade, said tail stock including a dead centre component for engaging and supporting one end of an associated work piece, and a live centre assembly mounted towards the other end of said bed plate, said live centre assembly including a live centre component, and means to adjust said dead centre component and said live centre component independently and horizontally, parallel to the upper surface of the table top and relative to one another.
