ABSTRACT:
A sawhorse apparatus and a method of constructing a sawhorse is provided. The sawhorse apparatus comprises a horizontal top rail, support legs, lower leg members and a pair of diagonal brace members. The support legs may be notched at upper ends thereof to receive the top rail between opposing support leg members. The legs are firmly secured to the top rail. Opposing legs are interconnected at their lower ends by lower leg members. Diagonal braces extend from the top rail to the lower leg members to further support the top rail. The lower ends of the diagonal braces can be notched to receive the lower leg members. Additionally, the diagonal braces cross over each other, extending from one side of the top rail to the lower leg members at the opposite side of the sawhorse. The method includes appropriately notching the support legs to receive the rail and the diagonal brace members to receive the lower leg support members.
