These are the Cherry Saw Horses I built. Everything is mortise and tenon joints (no screws or nails) with Titebond II wood glue. I finished them with danish oil to help water proof them a little. Unfortunately, I also used them for many of the HVLP paint projects so they don't look nearly as nice as they do in these photos.

I have had over 4500lbs on these without any fear of failure.
