Scrap 2xs and the cutoffs from I-joists make strong yet quickly constructed sawhorses. Leg spread is determined by the center-web height and the flange width. In my experience, 2×4 flanges work well. All cuts are straight; no bevel cuts are needed.
These sawhorses go together fast with a framing gun and will easily last until the end of a job. They aren’t as nice as our fancy aluminum horses, but these wooden ones can be left on the job site without concern about theft. We use them for worktables and for storing materials off the ground. When the job is complete, we either recycle them or leave them with the customer.
