[Coral-List] coral skeleton density!

[francois SENECA]

Bonjour dear listers,

I am working on abnormal growth in Porites compressa. It seems to me that 
the skeleton of "tumors" is more crushable than normal branches. I would 
like to assess the density of both, could you give me any advises? I tried 
to make equal-volume plugs using a cork borer, but it is not accurate 
enough! Then, I would just have to weight them and compare... the right tool 
would be a tiny hole saw for dremel but it does not exist. Regular hole saw 
has too thick blade and no sharpened enough teeth that make too much damage 
to the skeleton! I need something of precison.

Any ideas is welcome, mahalo
                                               Francois.
