Machine for cutting and finishing curved wooden members with cut-off and routing attachments

A machine for precision cutting and finishing of curved wooden members, comprising:

• a. a generally vertically disposed column,
• b. a support assembly including a plurality of spaced, relatively narrow support guides, each connected at one end to the column and disposed to extend therefrom in predetermined radial planes generally perpendicular to the column,
• c. said plurality of support guides each having an upper support member disposed at a predetermined working height for mounting a curved wooden member thereon,
• d. a radially adjustable clamping assembly on each of at least two support guides, each clamping assembly having two locking jaws, at least one locking jaw being fluidly operated to move relative to the other locking jaw between an open and a closed position for holding and fixing the curved wooden member on each of the upper support members of the plurality of support guides,
• e. an elongated beam rotatably connected at one end to the upper end of the column and cantilevered to extend radially outward therefrom for movement in a circumferential arc over the upper support members,
• f. a tool support having one end slidably connected to the elongated cantilevered beam and movable to and fro along the radially extending axis of the beam,
• g. a tool holder adjustably connected on said tool support for generally vertical movement along a vertical axis transverse to the radially extending axis of the elongated beam and rotational movement with respect to the vertical axis,
• h. said tool holder having at least two tool connecting ends thereon, and a cutting saw attachment with a cutting blade connected therein, and a cutting saw attachment with a cutting blade connected therein on at least one of said tool connecting ends, whereby on movement of the tool holder, the saw blade can be positioned to make a finished cut along one exposed end of the curved wooden member in assembled position on the upper support member,
• i. moving means for moving the tool holder along said vertical axis, and
• j. counterbalance means connected to said moving means for counterbalancing the weight of said tool holder and any tools mounted thereon, so as to maintain said tool holder at any desired position with respect to said tool support.
