Final welding project for AWS Level II

I was required to build a piece involving pipe and make my own blueprints after it was finished. I bit off waaaaaayyy more then my other classmates. I found this picture of a cast iron drafting table from the 1800s. I had no blueprints to work from. I just gave it a look and started building it in my mind... Scaffolding legs, gears from a differential, a 1" solid bar for a drive shaft. Here is my progress.
