i built a tree stand out of bed rail by cutting slots and bending it in a rectangle then i bolted boards to it. i made one big one and one small one then i put two pc of sqaure stock between them with bolts fallowed by two chains from back pc to floor pc .i used a 4 inch ratchet strap to hang it to the tree.. one pc of board under the seat to hold it up and you have a nice little hang on stand,,,it even folds up to carry it,,it is quite heavy but it dont cost 350 dollars ..i bought ladder sticks to climb it and just hid em in a brush pile it worked great i belive its still on dads farm..and it dont use nails or screws
