[PSUBS-MAILIST] esmae update

["Brian Cox" <ojaivalleybeefarm@dslextreme.com>]

I finally plastered my upper portion of the ferro cement structure and I'm
now keeping it wet with wet burlap.  Unfortunately I was unable to keep the
tolerance for my pressure hull at 30" , so I will have to have it rolled at
29 1/2" in order for it to fit in there.  That will mean that when I get the
30" end cap I'll have to cut it in a bit where the diameter begins to
decrease, I don't think it should be a problem though.

Also it looks like I will be using a 190DC OM621 Mercedes diesel as my
surface power plant.  Those deliver about 55hp @ 4300 rpm, from what I've
read. I'm planning on sizing a dc generator to it and putting it in a
pressure vessel.  The pressure vessel will not be able to be round however.
The width will accommodate a 26" half cylinder on the top and bottom but I
will have to add about 10" in the middle.  I'm thinking some 3/4" thick wall
and if I can weld some extra supporting structure I will.  For cooling I'm
looking a running the lines out to the ocean water and exchange the heat
directly through those lines.  I just have to calculate the needed square ft
of transfer area.  A keel cooler.
