Cut the arms off the box, going to drill two holes in the sides and put Cat 0 pins and have the neighbor weld up the top pin location for me. That should let me use it this winter, I want to fill it and hang 4 suitcase weights off the back! I think about 400 lbs with the weights if I can find some steel to fill the box, if not it's going to get concrete in it which should give me about 300 with the weights.
