Tree Stand

Does anybody know how to make a treestand? bc ima go bow hunting opening day and i wannna build a treestand but i may just buy one and i already have a treestand where theres no later and you have to climb up and all the good stuff. Any way?

I made a big lounger style hang on last year but only sat in it once, I just looked at a photo of one and tried to copy it, I assume you're wanting to weld one up?
