He's a guru.
He has followers, er, acolytes. He gets them to do his DIY.
He makes odd stuff, sometimes designed quite badly, that is somehow supposed to be special. One example is a rack for router cutters, recently, notable for its impracticality and odd use of joints and glue. It wouldn't last five minutes in my "workshop".
I've watched a few of his videos. I've subscribed/unsubscribed to his channel a few times.
He is very good at teasing titles. Every time I get suckered it's the title. Since he recently made a "hot tub*" using barrel stave construction, I had simply assumed it was leaking. What a disappointment.

PS: I couldn't watch more than a minute or so. If it really was his hot tub leaking, someone please say, as that might be more fun.
* a cold tub is simply a wooden water tank.
