i have 3 1/2 in pvc tubes that will be screwed into a 2 by 4 by 10. but before the tubes are attached, i have three sawhorse brackets that will be countersunk so that the top of the scre doesnt interfere with the pvs. then ill attach 2 2by 4s on each sawhorse bracket which will be attached together at the bottom by one 2 by 4 for each pair of legs. each of those will have a footlong nail droven through it into the ground.
it hasnt been tested yet, bc i didnt build it yet, and its my original design
