Duct tape is good --- Gorilla tape is better!
Solo is right -- you can make do without a saw/hatchet. If you don't believe him though, get one of those bucksaws that fold up into one single aluminum tube. All the components come out of it, as it forms half the frame. Will cut through anything. DON'T get the plastic handled, folding bucksaws....the blades heat up and snap far too easily. Even if you think you're being careful.
