[meteorite-list] HOW TO CUT UREILITES?

[STARSANDSCOPES at aol.com]

Hi all,  I have to side with  Elton.  

The diamonds on the blade are what allow it to cut through  iron.  With a 
Ureilite it is diamomd against diamond.

A few years  ago Rob (Nakhla Dog) had a huge (Just over a kilo) Ureilite.  I 
said I  would put a polished face on it.  I had envisioned a beautiful  
cut/polish.  I was not willing to return it defaced so I kept at it.   I used over 
$2K in Buehler diamond disks trying to smooth out the damage I had  done with 
several blades.

Don't take the Ureilites lightly!

te he he-- I am skeptical, David--Blade loss would  be
greater don't you mean?  Be it remembered that
ureilites are chock  full with nano diamonds?  Seems to
me that is a war of attrition with  the diamonds. 
While the blade is cutting the Ureilite the Ureilite
is  cutting the blade; metal,diamond and, all.

Hello Dave,btw  I'd not  had the pleasure of snipping
you until now.  Consider yourself snipped--  welcome to
the clan.
