IDK,
Looking at his web site, all the pics, design etc, is his shop equipment. There are some nice ideas and attention to detail BUT, it is a small garage type shop. If this guy has been doing proto work for forty years it was someplace else. This stuff reeks of hobby shop, the wiring to his line reactor is far from conventional or within the scope of the NEC.
I get a kick out of the reactions guys with little to no actual shop experience have when they see stuff like this. Yea he spent a lot of time and effort on these projects and, he did a great job on finishing them. The stuff is great for his needs, it isn't what a 150.00 an hour shop would ever try do work with.
