Shop-Built sawhorses. I built these from quarter sawn red oak.
Simple curves create soft edges that won't damage the projects that I use these horses to prop up. The top of the sawhorses are easily replaced when they wear out. They are jointed to the legs with lap joints held in place with a screw.
A trestle assembly is a strong way to build light weight sawhorses. The sled feet are attached to the legs with a draw-bore tenon with a single pin in each joint. The stretcher attaches to the legs with wedged through-tenons.
I used a table saw with a cross cut sled to cut the tenons. I drilled out the mortises with an electric drill then used a chisel and mallet to clean them up.
Hammering ebony wedges into slots cut in the tenons expands the tenons for a tight fit. All the mortise and tenon joints are glued together with yellow wood glue.
Trimming the wedges flush to the endgrain of the tenons with a pull-saw.
Cleaning up and chamfering the through tenons with a shoulder plane.
Nesting sawhorses don't take up much space.
The top of each horse is easily replaced when it wears out. They are attached to the legs with a lap joint and screw.
All done.
