Apparatus for accurately cutting timbers

Claim 1

Apparatus for cutting large work pieces at precise angles comprising: means for supporting a work piece; a frame base having a work surface in a plane defined by a first and second axis, said frame base being pivotally mounted to said support means such that when said frame base is rotated around said pivot support and positioned at a selected angle with respect to said support means, said work surface remain in said plane defined by said first and second axis; a plurality of support members secured to said frame support base and mounted perpendicular to said work surface of said frame base; a plurality of guide means for moving along each of said plurality of support members; a plurality of support braces each having a first and further end, said first end permanently secured to said guide means, and said second end suitable for rigidly mounting the bar of a chain saw thereto; and a chain saw having a power source, a cutting chain and a chain saw bar for guiding and supporting said cutting chain, said chain saw bar having a long and a short axis which defines a cutting plane and said chain saw bar being mounted to said support braces such that said long axis of said chain saw bar is substantially parallel to said work surface and said cutting plane is perpendicular to said work surface so that said chain saw is raised and lowered as said guide means move along said support member such that said cutting chain can be moved through said work piece supported by said support means to precisely cut said work piece at said selected angle.
