What kind of Base you got? You might wanna try out one Sahara Smokes Bases they seem to me to be one of the more stable bases out there or maybe look into one of those KM Jumbo Vases.
Something like These....
(Might have to contact them and see they can separate the base for ya) Or search around and see if ya can find another vendor if not.
Heres a Youtube video Photolinger did for Sahara smoke vases.... http://www.youtube.com/watch?v=adMVie6BtFA
Homemade fix just off the top of my head.... put your hookah in a milkcrate or fabricate some kinda of prop to hold it up.
