These sawhorses are strong, yet they stack compactly. Build them from construction-grade 1x4s (for the legs) and 1x6s (for the top), glue and a handful of screws.
The legs are 32 in. long, which puts the horse height at about 30 in., the height of a standard table. Adjust the leg length to your own comfort level. The top 1x6 is 32 in. long, but again, adjust its length to fit your needs.
The trickiest part is cutting the sharp (15-degree) angle on the top of each leg. The best method is to clamp at least four 1x4s together and cut them on edge (Photo 1). Mark the cutting line on all sides because you have to flip the 1x4s over to complete the cut. A standard Speed Square has angle marks that’ll help you measure the 15 degrees. Then cut the legs to length at a 75-degree angle (15-degree saw setting) so they rest flat on the floor.
If you don’t have a table saw, screw the cleat stock to your workbench using spacers (Photo 2). That’ll keep the piece stable while you cut the angles with a circular saw. Note that the narrow side of the cleat is 2-1/8 in. wide. Make sure the legs are perpendicular to the 1x6 when you assemble them (Photo 3).
