The premise of this show, like many on that other channel HGTV, appeals to a large demographic for whom science is hard. People with absolutely no real engineering background show how easy this stuff is for ordinary guys with 'common sense.'
I suspect that there are professionals behind the scenes on a lot of shows like this so they don't get anyone killed, and the producers sued. That cannot be shown because it would spoil the illusion that 'smart guys' like Raney are improvising, and figuring it out as they go. I have a background in engineering and construction. I wouldn't watch any of this drivel were it not for my wife liking it.
