From the start, you can see this guy has a passion for what he does, which at times comes across as a little arrogant.
But make no mistake, he knows his stuff and puts it across well, even if you get the feeling he has no time for anyone who builds wheels differently.
If you want to build your own wheels, all you need to know is here. It's well illustrated and if you patiently follow the instructions (you cannot build wheels without patience), you can't fail. For me, that makes it good value.
Having said that, I'm keen to find another book on the subject, I can't help feeling there's more to learn. Perhaps I'll treat myself to the Jobst Brandt book.
