<DIV>I was thinking of testing both my battery pods to 600’ before I weld them
to the hull so that if there are any issues with leakage I would still be able
to get them on a lathe. I added two vents per pod with O rings so that I can
push/suck air across the batteries while charging so there are a couple of more
places for leaks to occur. I did the calks' and they weigh in at 295 LBS. each
dry with a negative displacement of around 30 lbs. I was hoping that they would
barley float with no batteries in them so that I could weight them just slightly
negative for ease of launching and retrieving but that’s not the case. I need to
come up with about 30 lbs. of positive buoyancy and don’t have any syntactic
foam so I figured I could strap some 4” X 4”, on them to achieve that. This may
be a dumb question but does anyone happen to know the per foot buoyancy of a 4”
X 4” in sea water? If not I’ll head down to the ocean and start testing.</DIV>
<DIV>I also mentioned the other week about my desire to omit the plate that is
welded to the pressure hull and battery pod of a K-350 and was wondering if any
one could comment on that.</DIV>
