[PSUBS-MAILIST] Group purchase of buoyancy foam?

[Alec Smyth via Personal_Submersibles]

Hi guys,

I want to add 120lbs of buoyancy for Shackleton for fresh water operations,
and am considering a material that is far cheaper than syntactic foam:

It comes in flat panels, available in several densities. It can be cut,
sanded, and used as is to the rated depth, but the depth rating doubles if
you coat it with epoxy paint. Here is an article describing its application.

I just got off the phone with the vendor, discussing how my dimensions can
most efficiently come out of the standard sizes in which it is produced,
and the bottom line is that I would order two panels measuring 80x11x2.75
inches. But here's the thing, they have a minimum order of $1500, and that
is reached by making it FOUR panels instead of my two.

Would anyone be interested in joining me to make a joint purchase?

Thanks,
Alec
