Foolish question here from an old-timer. Does the second level of horizontal lumber (let's call it shelving) near the floor provide the same amount of sturdiness to the benchwork construction as the old diagonal bracing that used to be placed in the corners and between the legs? I kind of worry about somebody leaning on an end of your benchwork and watching the whole thing collapse toward the other side. Didn't Westcott recommend gussets or diagonal bracing?
