I assume he is talking about Richard King. I don't think he has his own channel. but as mentioned Stefan Gotteswinter and Keith Rucker both have videos of the scraping skills they learned from him. (Rucker has actually hosted several of King's classes in his workshop)
edit: I clearly misread the end of OP's post. Definitely not talking about Richard King.
He did years of scraping before he met Rich, but he did take a Rich King class to learn power scraping. Made it easier to justify skipping the expensive class for me.
