Boxing/punching bag stand build

[le swiss]

Engineers from the construction/materials science type fields please shed some advice on this project. What's the simplest design for building a punching bag stand?
Criteria: freestanding/not bolted down (i.e into floors, walls, ceiling, et), stable, least corrosion & health/safety concerns, support 200lb bag, and minimal cost. So far it seems best solution is a pull-up bar design: 2 10ft posts with support legs and joined with a 15ft pipe, 2in+ thick (stainless steel, titanium, or other steel type).

le swiss,

Draw a free-body diagram.

I don't know how hard people can punch. Look up MIL-STD-1472, Department of Defence Design Criteria Standard Human Engineering. This usually is up on the internet. The latest version I am aware of is[ ]G. You may have to set something up and get a big, musclebound friend to hit it.

After that, a convenient design is something that can be fabricated by the resources you have available. Off the top of my head, I would think welded steel tube would be a good idea. Strong. No sharp edges, or things sticking out.

I used to train on one of these while growing up:

Still have it at my parents place, wish I had the space in my small condo for it, especially with gyms closed for the time being.

If you're looking for one I'd recommend it over the freestanding type that are filled with water at the base. Those are annoying because they move around too much, which isn't much fun in a small home gym.
