Drill two 2"X8"X4 foot pieces of Pressure treated lumber 5 inches twice(holes level in relation to the end of the board. Put four threaded rods 1/2" by 4 foot long into the holes and add nuts and washers to each end. Cut cardboard into 14" X 36" pieces(free at most stores), and stack the cardboard into the frame you have just built. Now tighten the frame until you are scared something will happen, or your butt puckers. Stand the frame on end so the cardboard is vertical. Put in the spot you will shoot at it, and cover the top with a lumber tarp (available FREE at most hardware stores---the big lumber companies ship the lumber to the stores covered in them). I WILL stop anything you can toss at it-recurve, longbow, crossbow, compound. When it starts developing a soft middle section, just tighten the bolts. I would not advise using broadheads in this thing---you WON"T get 'em out---too dense. But it is a good regular field point target & should last for years.
