I wonder why no one has commissioned a "how to" book from Bill? Granted a book would be a lot different than a website in format and style, but Bill's information is so much more in depth than any of the dust control books out there. I would think a publishing company could assign an editor to work with Bill and help him develop the info on his web site into a info-packed "how to" on selecting, designing, and building the most effective dust collection system for home shops.
