lol i dont' have a scale, i was guestimating. but it really is quite heavy, the handle buckles when i hold it. i suspect the 2 coats of paint saturated the cardboard. but no matter, it IS a prototype. the real one (when i get to it) will be made with sexy sturdy foam-board, oooh yea!
I'm working on one too, I'm trying to make it with wood, but it's hard :S Can't wait to see yours Foam might be my Plan B if I don't have enough patience...
But still pretty neat
