A guy here welds a 3 or 4" pipe to the center of an old semi wheel with the tire still on it then he fills the rim full of cement then he bolts 3 or 4 12' boards on it horizontally then nail's the windbreak boards vertical. He has hooks of some sort so he can lift them by the pipes then he just staggers them kinda like snake fence to keep them from blowing over. Uses them in the corrals also to make a quick portable pen.
