In combination with a table saw having a table top and a rotating dado blade with a perimeter cutting edge, a device for cutting a tenon into the end of an elongated wood stock, the device comprising:
- a main frame removably fastened to the table top;
- a rocker assembly affixed to said main frame, functioning to enable the rotation of a central shaft in an arc over the table top;
- said rocker assembly further comprising an axis shaft mounted perpendicular to the central shaft, functioning to support the wood stock along a hole in the longitudinal axis of one end of the wood stock;
- and
- said rocker assembly further comprising means for predetermining an arc of rotation of the central shaft and axis shaft, whereby a tenon is cut into the wood stock at the end mounted on the axis shaft when the wood stock is rotated around the axis shaft and into the perimeter cutting edge of the dado blade within the predetermined arc of rotation of the axis shaft.
A tenonizer assembly removably fastened to a table saw top, said table saw top having a circular cutter mounted at a 90.degree. angle to the table saw top, said tensioner assembly comprising:
- a main frame having an elongated bar removably fastened to the table saw top;
- said elongated bar further comprising a plurality of stabilizing arms and bearing mounting arms;
- a rocker assembly having a central shaft, forward and rearward outrigger arms and a depth adjustment means functioning to provide a predetermined tenon diameter;
- said rocker assembly attaching at said central shaft to said bearing mounting arms of said elongated bar of said mainframe, functioning to allow rotation of said central shaft above said table top;
- and
- an axis shaft projecting from said rocker assembly above said circular cutter, functioning in conjunction with said central shaft to support and rotate a wood stock having an axial bore therein in a predetermined position in relation to said circular cutter.
