This is the most frustrating thing I have ever tried to put together.  The directions are maddening and now I have wasted two hours of my Saturday morning and it has unsuccessfully been pushed to the side.  One side of what they call  the 'nipple' has a bolt attached, but it never makes clear if that is suppose to be non the top or on the bottom.  I have a wound on my hand from trying to tighten it up enough for it to stand on its on, but to no avail.  I don't know what to do.
