I used 3/16" steel and had to adapt the slots to fit. Even then I had a few issues but as you can see it came together quite well. Along the way I decided to modify a few pieces... ie: a bolt cut off and welded in to place at a hinge point or two.
So if you're looking to chill... have some fun... try one of these out !
