I've been trying to find some pics from the A-Line and BWT ranges. They have ones just like this and a bunch more that make it awkward as shit to shoot. They're great training though. Instead of diesel fuel, you should cover it with pig guts just to make to as awkward as possible.
I was thinking of laying down some gobs of contact cement on the platform and then just sprinkling broken glass on top... or... how about some nails driven upward from underneath... that ought to make for some good shit...
