I have built a few elevated box stands in the past. Most are 4x6 and I just dug into the ground set the post and ran than straight up and than I usually have a tree real close that I brace the stand to the bottom of the trunk for extra stability. I'm looking at building another elevated box stand, but I won't have any trees nearby for the extra stability, so I want to angle the post slightly outward to give it a wider base. Does anyone know roughly what angle these post should be compared to the floor? I know they sell brackets already made for this, but I"m cheap and can fab most stuff myself, just need to know how much of an angle the post should be.
