Im pretty much stuck between either using the metal "tub" of like a radio flyer or the "tub" of a wheel barrow. And im gonna use cinderblocks for the weight cause weight plates are kind pricy and cinderblocks are free
It cost me $22 to make and the harness(no pic) is a extra full-body harness that you would use to secure yourself in a tree stand that i cut the leg straps off of.
