 He might have been on to something wrt fabricating buoyancy vessels.Sean

Just had a look at Cliff's  PDF on Syntactic foam.   Wow very nice!  and there is a cost breakdown I see.  It is much cheaper than buying but still twice the cost of trawl floats.  Hank

 Alan,Yes I could save a few bucks and look good at the same time :-)  I doubt I could make foam for less than trawl floats but maybe Cliff has a cost per lb buoyancy.   There is syntactic foam available that you mix together into your own mould also.  I am also still woking on the titanium spheres.   I have time to sort it out.Hank

 Hank,you could go on a diet :)There is this pdf on making syntactic foam by Cliffhttp://www.psubs.org/design/PDF/SyntacticFoam.pdf
I went to Alvins 50th Birthday party in New Orleans.They said the syntactic foam on it cost $3million. That included all the pressure testingof the individual segments.Alan

Yikes! syntactic foam is costly.  Syntactic foam for 1,000M is 8 dollars per pound buoyancy- trawl floats are 3 dollars per lb buoyancy.    I need almost 1,000 lbs buoyancy.Hank
