  • Patent number: 6293320
    Abstract: A precision multi-purpose machining apparatus for facilitating lathing, milling, drilling, sawing or routing operations typically using a rotary-type cutting tool. In a preferred embodiment the multi-purpose machining apparatus of this invention is characterized by an elongated support frame and a cutting tool mount cradle which is adjustably mounted on the support frame for receiving a cutting tool, such as an electric-powered DREMEL (trademark) rotary cutting tool. The support frame is capable of resting in a horizontal position, in which the cutting tool can be fitted with a cutting tool bit and the frame fitted with alternative workstock mounting attachments, to facilitate various lathing operations on a wooden or aluminum workstock. Alternatively, a saw table and saw blade can be removably mounted on the horizontal support frame and the cutting tool becomes a saw motor, the rotating shaft of which is connected to the saw blade by means of a drive belt, to facilitate various sawing operations.

  • Patent number: 5535652
    Abstract: The invention comprises an automatic lathe apparatus adapted to be programmed for automatically cutting work pieces into contours with a pair of radial saw blades. The apparatus has an elongated frame with a center drive mechanism movably mounted on the frame intermediate the ends of the frame to accommodate variable length work pieces. The center drive mechanism provides opposing drive spindles independently driven to engage a pair of work pieces at one of their ends and drive them thereby. A pair of tail stock spindles are movably mounted and adjustable at the ends of the frame and have air operated cylinders to drive the spindles into engagement with the other ends of the work pieces. A screw operated platform is power driven by a screw to drive longitudinally along the length of the frame.

  • Patent number: 5333657
    Abstract: Apparatus for turning and milling a workpiece includes a frame having a chuck and a spindle spaced laterally of the chuck mounting respective opposite ends of the workplace for rotation generally about its longitudinal axis. A carriage mounting the milling device is supported by a rail on the frame for movement generally side-to-side of the frame and longitudinally of the workpiece. A first variable speed electric motor operatively connected to the chuck for driving the rotation of the workpiece about its longitudinal axis is controlled by a first control, which is used to selectively set the rotational speed of the workpiece.

  • Patent number: 5065802
    Abstract: A dado lathe is provided for use with a table saw in performing numerous cutting operations on a piece of wood stock. The dado lathe device includes a pair of parallel, spaced apart guide rails upon which a frame is slidably mounted. The frame includes vertically and longitudinally adjustable headstock and tailstock spindles for rotatably supporting the wood stock. A drive system selectively rotates the wood stock while moving the frame longitudinally along the guide rails. Using the dado lathe device, a square wood stock can be turned to a round wood stock, spiral and grooves can be cut in the wood stock, the wood stock can be tapered, and beading and reeding can be cut along the length of the wood stock.
