Sorry i guess the word would be spreading apart more than buckling. I think the main problem with the small horizontal brace, the one that separated is the 1 1/2 difference in flatness with the X pieces not being notched. The one end is screwed flat against the one X piece were as the other end is toe nailed(screwed) into the other X piece. This is what let go and spread, the toe nailed end. From the answers received so far, it look like if i do a 3/4" notch on both pieces and at least one lag bolt with some screws, then add an upper and lower X member brace that will now be flush should do the trick. Thanks all, i now have a small winter project to stay busy.:-) Dave No stringers there, so > maybe just a diagonal brace from end to end attached directly to the > legs.
