[meteorite-list] techical advice

[Ed Deckert]

Dave,

I have no experience with such matters, but I would go the "mechanical" 
route by using an fine abrasive stick instead of a torch.

I may be completely off base, but if there's a chance for some kind of 
damage due to thermal stress caused by heating the LDG (like shattering or 
cracking,) I wouldn't want to risk it.  Others may have done similarly 
without problem, but then there is the famous Mr. Murphy and his Law...

That's my 0.02, for what it is worth.  Good luck, whatever you decide to do.

Ed
