You will need to email me to get a password to open the file. The link to do so is on the download page. When you get the password, please DO NOT share it with others; let them email me to get it. I do want to maintain some level of control on the dissemination of this article.
A person emailed me the following concern which I would like do address while preserving his anonymity:
"I saw your post on the metal polishing article, and would like to see it. I assume the password request is to keep the people *not* really that interested in the article *out*, and those who want to learn more in?"
-------------
Let me put everyone's fears and misgivings to rest:
It's nothing as subversive or selfish as that. I just don't want some publisher finding the article and running it in their magazine or web site without my permission and without compensation to me.
I have a constant and ongoing problem with copy and photos from my site appearing in all sorts of places -- people have even emailed me from overseas countries advising that my photos have appeared in glossy high-end magazines!
Of course the worst offenders are eBay users and that's what gets my goat the worst. People have not only directly ripped off copy from my site, they have placed links to it without asking - increasing bandwidth to my site and more than once causing me to incur costs and in one case causing my site to be shut down because of the excessive traffic to it, and some people have even used MY photos to sell THEIR vacuum cleaners!
Some f@#khead in Taiwan has published the entire contents of my Theremin History article (www.137.com/history/...) on his or her site. I have no idea who this person is or what other content is on the site because it's all in Chinese so the characters appear as gibberish on my (Western character set) screen. I did scrounge around the underlying code and found a couple of email links which I sent emails to, asking that my article be removed. Naturally, I never heard anything back, and the last time I checked my article was still there.
Publishing materials on the Internet is always risky; especially useful "how-to" articles such as my metal polishing article. The only way to keep materials from being stolen or plagiarized, and to keep track of who is accessing them, is to password-secure such materials. Fortunately, Adobe Acrobat's security system is very complex and nearly foolproof.
Anyway, hope this clears up any concerns. I am more than happy -- thrilled actually -- to share my experience and knowledge with anyone who has a legitimate interest in it and use for it. But I do not want to open the next issue of Popular Mechanics and find my article in it; or have someone in Sri Lanka send me a link to my article on some web site in their country!!
