That is REALLY cool. I love it. The top of that lid looks like you've polished it to the point of it being near chrome like.
The only thing I see, is that little handle. I can picture myself grabbing that handle and trying to move that beast (that weighs a few multiples of me) and not getting very far before I run those 2"x2" legs throw my socks and slice major flesh. Your "lever" needs to be longer to get your feets and legs away from the sharp stuff.
Otherwise, that's a awesome rig. I need one.
