I had two 50 gallon oddly shaped water tanks fabricated out of food
grade polyethylene a few years ago for about $500 each delivered. I'd
say you ought to keep looking.

I say keep looking too. The actual process of making these is neither
difficult nor expensive. Like any other kind of welding, you could do it
yourself with the right materials and some practice. The only reason some
charge so much for it is, well, that's what they can get.

Bob,
Go to that link and click on the About Us tab. Any idea what language
that is (I don't recognize it) or what it says?
It is nonsense Latin used by typesetters as an example of how a font
looks.

In the publishing world this practice is technically known as "Greeking". Using
Latin for Greeking is pretty funny. Usually it is just random letters used to
fill the spaces where text will go while working on layout and design issues.

Actually, the phrase "Lorem ipsum dolor sit amet..." has been used for
a long time for greeking.

It is Latin. Looks like a place-holder for the real text... don't know
where it went...

Ye gods...who tried to hold you up for that price???

Ronco Plastics makes top quality thick walled rotomolded polyethylene
tanks for a very reasonable price and has more than 400 shapes and sizes,
over 100 of which are non-rectangular...and they install fittings in the
sizes and locations specified by the customer when they make the tank.

Ronco does NOT fabricate custom tanks, however...they don't make welded
tanks, only the rotomolded tanks for they have molds...and the cost of
making a mold for a one-off would be prohibitive. If they don't have a
mold that suits you, there are two companies who do make custom welded
tanks for a reasonable price:

http://www.seafabtanks.com/

http://www.triplemplastics.net/

They both use polypropylene instead of PE, which is fine for water or
waste holding.

When the told me over the phone " twelve hundred dollars" I said "one
thousand two hundred dollars???" I was certainly taken aback considering a
friend told me he had a tank made by them "a couple of years ago" for
something like $300. "Oh the cost of crude oil has gone up so much the
plastic is really expensive". Yea, especially if you are a gouger.

I can see why the roto molded tanks would be much more reasonable in price
but $1,200 is pretty rediculous for a custom tank.

I'll check out the two links you provided. Thanks for that and thanks to
other respondents.

I agree...which is why I'd like to know who quoted you that price so I
can be sure NOT to recommend 'em.

If you'd rather tell me privately, my email address is (my.name)at

Gordon,

The holding tank on my boat is an oddly shaped trapezoid, about 7 feet
long, that follows the curve of the bilge. When the PO's previous
disastrous attempt at building one failed (a ugly story in itself), we
built our own, using fiberglass, about 1/2" thick, with baffled walls,
air vents, access ports, etc. It hold more than 50 gallons.

The entire project's cost was under $500, and we had a lot of epoxy and
cloth left over. We used additives that made the glass less porous to
liquid or oder. It has worked well ever since.

Because it was our first exploration into using glass, it was probably a
bigger job than it should have been, but even still, we couldn't find a
cheaper alternative, given the odd dimensions we were trying to fit.

Given that todays epoxy prices have increased I'm not sure how cost
effective this might be, but compared to the prices you're quoted, it
still sounds like a better solution.

If you want additional advice about it, contact me off list. Good luck
with your project.

Cheers,

Robb

for a tank that might hold 15 gallons. It would be prism shaped, 30 inches
long, 20 inches on each side and 18 inches across the top. I figure there
might be 25 square feet of plastic at most. I was told the material alone
was $800. That's something like $30/square foot. Is that what 3/8" thick
poly sheets go for these days? I didn't think those plastic cutting boards
you buy at Wal Mart cost $30.
So is this the going rate these days?

Yes, I know. I just find mild amusement in the idea of using Latin for Greeking.
Is that okay with you, Jeff?

Indeed, when I first heard the term, about 35 years ago, I was amused.

However, I was commenting on the fact that "Lorem ipsum ..." has a
long history, it isn't, as you say, just random letters. Is that OK
with you?

I asked my local plastics supplier, Industrial Plastics (Nanaimo) for the
quote but I think they just send it to another company in Victoria, BC.
Don't think you would accidentally recommend them to anyone.
What do you think of the idea of fabricating a holding tank from plywood, FG
cloth and epoxy as suggested by AMPowers? A friend is thinking of doing
this and I might consider it as well.
