I built this stand for guys 250# plus. I wanted a stand I could leave out on my lease all season and would accommodate a few of my heavier friends nicely. I call the stand "The Fatboy Deluxe". It measures 33"x27" its like standing out on a deck. There is enough room where you do not need to flip up the seat. I put over 400# on this stand at work and it does not bend,flex,sag,creak or anything. I used 1 1/2"x3/4"x.105 steel tubing for frame and grate was from Pallet racking. I will be posting more pics as I finish the stand.
Nice Kevin, I have one of those heavy duty ones to I made, it stays out year round like your wanting to do.
That thing is beefy for sure! You are going to need a crane to get it in the tree LOL. How much does it actually weight?
I've made afew in my day too that I left out all year. You have to watch out so your tubes don't fill up with water and freeze. This can split the tubes open and ruin the stand. Don't ask me how I know this.
Fill the tubes with some great stuff or something. That will help them stay quiet and keep them from getting foreign objects in them.
Thats a nice looking stand. I made a few like that (not near as nice lol), and filled the tubes with the Great Stuff foam. Be sure your completely done welding though, the foam sure does like to burn :D
