[modeleng] Re: flat belt grip

Barry,

Over here Kitty Litter and "Oil Dry" are made from a clay called 
"Bentonite".  There used to be (may still be) a Bentonite mine near 
Louisville Mississippi and the black laborers who worked there called it "de 
dirt factory".  About 5% powdered Bentonite is mixed with sand to make 
molding sand for foundry use and it is also used in oil well drilling among 
other things.

Fuller's Earth is I believe composed of zillions of tiny silicon skeletons 
of Diatoms and is also called Diatomaceous Earth.  Great for filtering oil 
when re-refining it and also a great insecticide if you get fleas etc in 
your carpets. (It gets into the joints of the insects exoskeletons)  Only 
one problem, the stuff is highly abrasive and will destroy a vacuum cleaner 
in only a few minutes unless it is a wet or dry shop vac where the material 
does not pass through the motor.  It will go through the filter bag of 
canister, and other vacuums and into the motor bearings and commutator.

 tho................
