So I have some sort of basic idea of how to build this pull up bar, I have a very specific requirement for it though that I am unsure of how to to go about. I need it to be able to fold out from the wall of my garage. The bar itself would be some sort of metal pipe. How can I go about having hinges to attach to the wall so it can fold out and still be a decent height to attach rings and be used for pull ups? via /r/DIY http://bit.ly/2Z0VWm4
