I was unpacking my new Powermatic 54A Jointer yesterday evening and noticed
Powermatic's suggestion for table rust protection. Sprinkle talcum powder
on the table and rub it in with a blackboard eraser. They say the fine
powder fills pores in the metal and blocks moisture intrusion. Should be
Anyone else heard of or tried this?
It dries quickly, there's nothing to fling off!
Don't you live in Texas? You probably wouldn't get rust if you used
cooking oil. <G> Here in the Northeast, metal can rust if you look
at it wrong, and all the chains we get that were "lubed" with WD-40
are rust buckets.
The only part of a chain that needs lube are the internal pins, within
the bushings. Chain manufacturers, like Shimano, Sachs, and SRAM,
install a grease when they assemble the chain. WD-40 will remove this
grease and leave nothing. If you really want to prevent rust and lube
the chain, without buying expensive "bike specific" products, use
chain saw bar oil or air tool oil. Wipe as much as you can off after
you apply it. The film will last a good long time. Even better are
the dry lubes and wax based lubes sold for the purpose.
Anything left on the outside of a chain simply attracts dirt, which
grinds your expensive chainrings and cassettes away.
Your chains may not rust, but they're no longer lubricated, either, if
you're using WD-40.
Who puts 4-5000 miles a year in a bike saddle, some of it off-road.
I learned to use ATF on my bike chains almost 35 years ago. Once I
clean them off I soak them in a tin can and heat the ATF on my stove at
a very low heat. ATF is flammable so you have to be very cautious when
doing this. After the chains have soaked overnight I hang the chain
vertically and let if drip back into the same can until all the excess
has drained. The lubrication is good for several months of hard riding.
Well, if you can find talc powder. Most of what we call talc powder
seems to be marketed as 'baby powder' and is actually largely corn
starch if memory serves.
Talc powder is finely ground soapstone I think - not sure I'd want that
getting into my bearings and such. Think I'll stick to waxing the
surface of my machines...

And a good thing too, as a lot of talc contains asbestos.

No, this is quite unreasonable scare mongering. In no possible way
does "a lot of talc" contain asbestos.
Talc and asbestos are both amphibole minerals (a whole lot of minerals
are amphiboles - if it's a calcium / magnesium silicate, chances are
that it's an amphibole). _Some_ talc deposits have associated asbestos
deposits with them. _Some_ talc minerals have been mined from these
deposits, leading to contamination with asbestos.
In _ONE_ infamous case, a study of the talc filler used for making
children's crayons was found to contain a miniscule, but detectable,
level of asbestos. Cue instant hysteria from the "Think of the
_CHILDREN_" brigade. This trivial and insignificant case has been
blown up out of all proportion ever since.
If you're selecting talc to make cosmetic grade talcum powder, you
didn't use these deposits anyway. You wanted something that milled
finely, and the last thing you need is some tough old fibre in there.
Got any houseplants ? Any of them potted with vermiculite (those
white spongy granules, to improve water retention) ? You'll get more
asbestos exposure from those than you will from talc. In the waords
of that great sage, John Otway, "Be careful of the flowers 'cos I'm
sure they're gonna get you, yeah"
Now flame away. I'm so chock-full of asbestos I'm fire-proof.
I fear that Mr. Barss may be putting lots of that crap into poor,
unsuspecting students' minds on a daily basis, to their detriment.
I have at least 4 of his emails in my killfile and just added
another one this week, when he came back with a new one. His info
seems as valid as that of BAD and Joe Woody Woodpecker's. <sigh>
More info here:
We all now know that inhaling organic substances into our lungs is muy
peligroso, but the USGS points out that inhaling large quantities of
asbestos fibers is even more dangerous to smokers. (People who are
already killing themselves. Doh!)
Another dire hazard in working with plants is the exposure to another
deadly chemical: Dihydrogen Monoxide. Scary stuff, and it's more
deadly than asbestos. More here: http://www.dhmo.org/
MOST installed asbestos is not the deadly type, nor is it in everyday
contact with anyone's lungs, but the guys testing for and removing it
are making MILLIONS. What a scam!

Larry, the one on Global Warming is unfortunately mis-classified as a
scam. It is happening. And, no, it's not "junk science"- as if "W"
were familiar with either. Science _is_ the search for the truth,
You are partially correct. Science should be the search for truth. The whole global
warming issue is too politically charged to be
treated as such. There have been some recent studies that question the leading
research into global warming. Of interest is the
Mann et. al. study that introduces the "hockey stick" graph showing that in the last
century temps have been rising dramatically.
Other researchers using their data and computer code have found that regardless of
the data fed into the model, the graph has the

Science searches for fact. "Truth" is a philosophical concept.
Science answers the question how. Philosophy (or religion) tries to answer
That said, I wouldn't let SWMBO sit on any talc-protected tool.
Several years ago I was at a meeting at which it was suggested that
the long-haired researchers in attendance be care to not say "Global
Warming" instead they should say "Global Change."
Makes sense, especially for the ones studying plate tectonics.
