Simplicity is amazing isn't it. Makin' due with what one has is within all of our grasps. He overcame fear and did what he wanted to due; some would say that is crazy I say cheers but it comes with a price. ;) I wonder what he thought of his dream when it was all said and done? The hinges are fine though aren't they. Ripping lumber with the right tool just takes time and time he had because he made it.
