Things You'll Need

Instructions

1

Stand the sawhorse beam up vertically, centered on the plywood with the edge of the beam flush with the edge of the plywood. Lay two of the legs out on their sides on the left and right in their angled portions as if they were already attached to the beam.
2

Lay a straightedge along the bottom of the legs as if the straightedge were the floor.
3

Hold the straightedge in that position. Remove both legs and the beam and draw a line down the straightedge to represent where the floor would be.
4

Measure from the top of the plywood to the line for the exact height of the sawhorse.
