Hi Frank.

$80 for a 2ft x 10" OD pipe?  That is soooo cheap compared to what i could get it for here.  I could probably fly over and fetch it cheaper than buying it here.

Im just trying to get the 12" A53 pipe sorted for my battery pods and the cheapest offer ive got so far is ?75 / meter.  About $140 / 3 ft.

Caps are ?48 each ($100)

Im still ringing round places to try and get it cheaper.  My problem is being on a small island with very limited resources.  Im sure there are places in the UK i could get the stuff cheap like your recycle yard, but where they are i havent a clue.  Plus im not there to go and look.  Ive just got to keep ringing places up.  Also when you say you only want 6 ft or so of it, they almost fall over laughing.

I'll keep ringing places for now......

James

Hi James. Yes, The cost of those "lite" tanks seems quite low to me. No way
could I build a tank for that and have the connections and all. Because my
tank  is inside the hull, I like the idea of being able to see the water level.
The  idea is to be able to add water to a pre-determined level while at the
surface  depending on what buoyancy is needed. Small adjustments can be made
while still  shallow so no really high pressure would be required. If I needed a
little  adjustment at depth though, the tank can still take it. I can see the
water  level, and add a half gallon or remove a half gallon. ( that takes a
pump )
     If the tank was outside the hull, I think I'd  probably go with a
stainless one. I saw some SS pipe at the
recycle yard and a two foot piece of 1/4 " X 10" was about $80. End cap
plate, and fittings would likely add another $100 or so. A little pricey but not
out of reach.
