Jamie, is the "U" channel one piece of wood or 3 pieces, I could not tell from the pictured? Also what kind of hinges did you use . I really like your set up, having a small work shop I have to cut my sheet goods outside and I have to go to the RV shed to get my saw horses then bring them back when finished. I have been putting off making a new set of horses so now would be the time to try yours especially since they take so little storage space. Also what size lumber did you use for the legs ect.
