1. An adjustable saw horse for cutting 2×10 and 2×12 sized lumber, said saw horse comprising:
a plurality of leg support members having a trapezoidal shape, each said leg support members further having top and bottom portions, said top portion being provided with a notch formed therein and extending downwardly therefrom wherein said notch terminates above a midpoint between said top and bottom portions, said leg support members being removably positional on a ground surface and maintaining a fixed spatial relationship defined along a linear axis during operating conditions, said leg support members further having substantially planar front and rear surfaces monolithically formed with said top and bottom portions, said bottom portions having bottom edges for resting on said ground surface;
a plurality of support arms pivotally connected to said leg support members, each said support arms having top and bottom edges terminating below said top portions and registered horizontally with said bottom portions respectively, each said support arms being adaptable between folded and unfolded positions defined at parallel and perpendicular angles with said leg support members respectively, said support arms are coextensive, wherein said bottom edges of said support arms are coplanar with said leg bottom edges of said support members respectively;
a first elongated support beam having a rectangular shape and being removably positioned into the notch such that said first support beam extends downwardly towards the midpoint, said first support beam having opposed end portions laterally situated away from said leg support members in such a manner that a major longitudinal length of said first support beam is horizontally intercalated between said leg support members;
a second support beam removably positioned in the notch wherein said second support beam has a planar bottom surface engaged with a top edge of said first support beam, said second support beam horizontally extending along said top edge of said first support beam and defining a work surface registered perpendicular to said first support beam; and
a plurality of rubber pads engaged with said bottom portions of said leg support members for assisting to maintain said saw horse at a substantially stable position during operating conditions;
wherein said second support beam have a longitudinal length greater than the longitudinal length of said first support beam;
wherein said leg support member have opposed outer edges converging upwardly towards said top portions respectively;
wherein the notch is T-shaped for selectively receiving said first and second support beams and maintaining said first and second support beams at substantially orthogonal positions during operating conditions;
wherein said leg support members are coextensive;
wherein said support arms have respective fulcrum axes extending parallel to a lower portion of the notch such that said fulcrum axis is registered medially between said outer edge portions;
wherein said first support beam extends parallel to a centrally registered longitudinal axis passing through said support second support beam;
wherein a first one of said support arms is offset to a left side of the centrally registered longitudinal axis and a second one of said support arms is offset to a right side of the centrally registered longitudinal axis;
wherein said first and second support arms are positioned on opposite sides of said first support beam such that said first and second support arms do not lay along a single plane.
