When I attached the lower shelf to the legs, the shelf split at 3 of the 4 attachments.  Apparently I was tightening the screw locks too much.  In fact I snapped on of the metal screw lock thingies.  I really didn’t think I was tightening them too much, but be careful.  The table is stable enough even with the cracked shelf once I attached the top.  It’s a cute table, just don’t tighten the screws too much.
