I don't know if this will help, but I think it was John Monroe (sp?) that had a pretty extensive thread on his experience building a floating island. It was about a year ago?

Edit: here is the thread I was thinking about http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=298434&page=6 . Apparantly is was started by AP and then Monroe tried his version starting around page 6.
