<div>I thought I had some lengths of 4” X 4” laying around but was wrong so I
used some 2” X 4”’s which I had plenty of and it took 25 feet of 2” X 4”
lumber to make it neutral which looks like about 48.46 cu in of wood buoy 1 lb
after the lead is submerged as well as the displacement of the wood. I am sure I
will loose some buoyancy from the wood at depth but not enough to make it a
hassle to haul back in by hand. If the pod floods then it’s plan B, using some
lift bags in stages to get her back. I’ll let ya all know how they tested
out.</div>

<div>any idea what the two floats provide in buoyancy?</div>

<div dir="ltr">Hi Rick, here is a quote on the floats I just got. The 551
float is $10.80 ea., less 10% per carton of 18. The 364 float is $6.00

for 18 or 72. </div>

<div class="yiv3255069131MsoNormal"><span style='font-family: "Calibri", "sans-serif";'>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.<u></u><u></u></span></div></div>
