Is this a double secret website or something? About a half dozen posts
in a couple of threads the last few days and not one URL.

A web search yields hardly any hits on the topic and virtually all of
them refer to the one Australian occurance in that cite. Makes me
wonder...

Yes... very secret... would have to kill you if you found the website.

LRod, did you *read* any of the recent threads on it? The truth is out
there - but you have to *read* the messages to find out.

The reason there's no URL given is that you can't get in without a
username and password and you can't get a username and password until
you are invited by a current member. But, you can get an intro he
http://www.thewows.com

Here's a copy of my post that started it all (replying to Tom Nie):

By the way, you seem like a good candidate to enjoy the World of
Woodturners. It's a private group that was an idea a past newsgroup
participant came up with to share photos, get and offer critiques if
desired and just post about woodturning. There are hundreds of members
from novice to professional and thousands of pictures. To participate
you need to be invited by a current member - but anyone is welcome to
join. Be forewarned though, if you are a bad site citizen you'll be
kicked out by the cops.

Tom, if you or anyone else within the sound of my tic-ticking keyboard
would like an invitation drop me a **private** email at my address
above. In the email indicate a real email address for you to receive the
invitation with your user name and password.

It's serious enough for Lee Valley to have written a warning about it --
was in one of their recent catalogs.

Thermite is some serious stuff -- a few ounces can burn through an engine
block, apparently.

If you seriously want to expand your creativity as well as seeing
pictures of the "cutting edge" of woodturning, membership on WOW is a
necessity. The membership and invitation thing is only because of the
weird program they use. But it does allow easy, seamless viewing of
wonderfuly pictures of woodturning. Much better than any other service.
Anybody will get accepted that wants in.

That group that'd have you for a member...? I thought Twain said that.

The WoW site may be a little different than you're thinking with a Yahoo
group. What's your concern?

It's really like this newsgroup except in web format but with the
capability to post pictures, offer critique, etc. without any unruly
trolls. (I know that's similar to Yahoo but I'd like to know what it is
about Yahoo that you don't like.)

But if you don't behave yourself, Herm will terminate you. That was one of

Ken,
That "termination" doesn't sound like a bad thing. Though as a newbie I
haven't seen any reason on this NG to worry about it.
And the pictures ARE awesome.

Requires a magnesium strip or powder to ignite it- sparks off the
grinder aren't hot enough. But FWIW, I wouldn't grind aluminum
anyhow- clogs up the grinding wheels. Better to use a sander or saw
it. No doubt LV has it in the catalog as a CYA measure for the one
virtually impossible case of it happening.

I wouldn't worry awfully much about thermite, though. Even if you try
and make it intentionally, it's not all that easy to do. Iron or Iron
Oxide needs to be extremely fine, ditto for the aluminum, they need to
be mixed properly in the correct proportions, and it requires burning
magneisum or something equally hot to light it (which needs a
blowtorch to ignite in and of itself.) Miss any of these things, and
it's not going to happen. Seems more likely to me that some oil from
the outside of the metal could smolder inside the hood on the wheel-
seen that happen before and it can get pretty hot, but it's certainly
not thermite.

Hi Prometheus

I kind of agree with you, but you have to keep in mind that some people
think they are grinding aluminium when they are grinding magnesium, I
remember an event in our shop when my brother and I where building a kid
scale 53 Ford that was to be powered by a 3 hp B&S motor and we needed a
light transmission, and so he was cutting some steel of the transmission
housing we where going to use, when it started burning, it surprised us
to say the least, we had not considered the housing to have that much
magnesium in it, but had considered it to be just aluminium.
Sure gives a lot of light and smoke.

Have fun and take care

Hmmm. I recall a kid who got in trouble for placing magnesium wire in the
candle snuffer at church. It ignited without a blowtorch. Of course, I've
always felt God has a sense of humor. No other way to explain some of the
phenomena of daily life.

Could be a matter of surface area to volume ratio. I know the little
bits I played with back in high school chemistry needed a blowtorch,
or at least one of those butane *jet* lighters to ignite it. Might
have had something else in it to allow it light more easily as well,
never can tell what someone else has got going on, after all!

You mean like grown men and women hacking on a hunk of wood as it spins
at high speeds and calling it fun? Yeah, seems sorta weird. ;-)

I don't have a candle to measure its flame temperature, but doubt if it is

thinking they get that hot.

It was whatever they put in flashbulbs - thought it was Mg, might have been
Al. At any rate, did the job.

Surprisingly, to me at least, I found...

"A laminar diffusion flame is a candle. The fuel comes from the wax
vapor, while the oxidizer is air; they do not mix before being
introduced (by diffusion) into the flame zone. A peak temperature of
around 1400°C is found in a candle flame [3]. "
