Re: [PSUBS-MAILIST] shapeable incompressable filler..any ideas?

[jeffpost@rawbw.com]

As always, I'm going to suggest not scrimping, and doing it a proper, tried and tested 
way.You could of course make your own syntactic foan by mixing glass beads and 
epoxy. The glass beads  will be essential non-compressible, especially at the 
working depths of an ambient pressure sub, and the epoxy will stick powerfully to just 
about anything. It would be shapeable; you can mix it thick and try to shape it as you 
position the filler, and it would be able to be tooled when hardened.

As with all things marine, and especially all things submarine, it doesn't pay to look 
for cheap shortcuts.

How much volume are you trying to displace?
