Jim,

Good thoughts, but glass and even fused silica are unfortunately 
quite weak in tension, ~7000 psi under ideal conditions.  Very few 
materials can reliably achieve the yield strength of the 17-7 
stainless we're using, ~300000 psi. = 2.1 GPa.

Perhaps before I begin seeking solutions, I will try to figure out 
what problem I am solving.  :-)
