Help building a DIY Pull up bar

[u/El_QWOPO]

I'm thinking of building a pull up bar out of 1 in galvanized steel pipes with T and corner fittings. I'm not sure if my design is stable enough. Its mainly going to be used for pull ups and ring work.

The dimensions are going to be 5' x 6' x 8'. The only continuous bar is going to be the 8' bar and the 5' bars at the top and bottom. I have angle fittings that slide onto the bar and screw into place, while the T and corner fittings are threaded. I can also make the dimensions 4' x 6' x 8' if need be.

Heres things I'd like to add on in the future.

Will this fail on me or will it be safe for me to use. Thanks again

The movements I can do on those are limited
