    What in heck are you talking about? I need more input (like #5), more Input!

    Remember, I am Canadian - I do not listen to Rush Windbag!

    Dave- no problem, I thought it was funny also . I have NO use for a person who can spell a word only one way (courtesy Mark Twain), I seldom make so fitting a mistake.

    May you all find many more as good & point them out.

    Relax - it was a hoot! I read grain dust too (brain thinking instead of reading) - so don't feel bad. Those test to see who's paying attention - you had it all planned, you sneaky bugger!

    read it again, bud- I said "should" not "did or do". I bet I read my "Brain Dust" post after I posted it and every time I read it it said "Grain Dust". Since it went up right at 2 Pm and was wrong by 8:30 when Composite found it, it must be Neil's fault. To Whom and where do I lodge a complaint?
    Peace, Gents

    Don't blame macroslop for your airrors - you no bill gaates nevur makes missteaks. I uze thair spel cheecker awl thu tyme and I doant git mistaks! Four sham, Steave...

    Brain Dust: n. - what you get when you put your nose to the grindstone too long without the right coolant, also that funny smell in your mouth when the dentist says "oops! nurse call this number - quick"

    Re: Brain dust.
    Gents please be informed that ALL my posts should go through Microsoft spell check, etc.
    Microsoft agrees that "brain dust" is a OK phrase- when I use it. Microsoft also approves of "grain dust"- which explodes also, Drain dust which is rare,Krain dust is a protected specis, Train dust is now rare.
    Hope you are more aware than before

    Zirconium was used in cluster bombs ond other high explosive applications.

    After Steve's warning about brain dust I will put the q-tips I use in my ears in the fire proof rag can and not the garbage. If I run a towel straight through both ears does this work better than the q-tips? I have seen Stimpy do this, but he removes his brain first with tweezers ("It's so small...!"). And should I use coolant in this procedure?

    It is doubtful you could get a high enough concentration of brain dust to explode. Brains will autoignite. Dumb salesclerks frequently seem effective with mine.
    As regards the rest of post, the link on Titanium was interesting. I have been trying to find similar information for other materials, such as iron, as I suspect information will be quite similar. Many MSDS's I found for Titanium listed autoignition and explosive limits as N/A. Iron too.
    Iron is very easy to get to burn, you can light steel wool with a match. It is not easy to extinguish either.
    The mention of dust explosions was generic, and should not be taken lightly, dust plus ignition source can be very hazardous.

    Any one dealing with metals dust should go to fire code and readup. Ground small enough, most will burn and even explode. Flour dust, brain dust cotton lint (as in clothes dryer) oxidize with ease and speed.
    Lee Valley catalog had a story (I think it was Lee- comments please) about a grinding wheel use for iron and aluminum that exploded. I've doubts about the story but it is possible given right conditions- I guess

    Thanks for the url - most informative. I was unaware of the 480* ignition problem with <100 mesh dust. I did not know paint dust would do that either until it set our dumpster on fire. I have seen the other metals I mentioned burn (along with Na, Li, & K in water) but have never seen a Ti chip burn. I stand corrected again - geez I am a dork. Twice in one day. I will have to try burning some now!

    Ti chips can burn. Been there, done that. http://www.titanium.com/tech_manual/tech15.cfm

    p.s. Ti has an oxide coating like Al and when cut this layer is missing and reforms on the hot chip in a vogerous manner called fire.

    Only thing I can think of is they are machining Zirconium - it will burn in the air if heated and looks and feels similar to Titanium. I was trying to figure out what was going on and that was the only thing I could come up with.
