Everything but the Kitchen Zinc

[Watson A.Name - "Watt Sun]

I saw this http://home.t-online.de/home/gollum/salt.htm and I said,
why bother with a half volt when I could make one with a volt or two.
I could build a crow's foot battery like back in old the days of
telegraphy.

I got some root killer for the stump I'm still trying to kill; it's
mostly copper sulfate blue crystals. I have some copper plate around
somewhere, or I could use a piece of PC board. But where do I get
some zinc? To make a crows foot? I remember that my dad's drinking
buddy used a zinc sacrificial anode on his sailboat to keep the rest
of the boat from corroding.

This battery sounds so cool.

Some of the cells sound like they would be toxic waste when used up.

Residential water heaters have sacrificial anodes... probably zinc. I
think they screw in through a tapped hole on top.

Oh: here is one

They show their rods as being aluminum or alum/zinc/tin.

Yep, went by the local marine supply place in Alexandria VA and they
have hundreds of pounds of zinc anodes in lots of different styles.
Not too expensive either.

Thanks for the info. I guess I shoulda kinda said where do I get zinc
locally? There are welding supply shops locally, I wonder if they
have zinc in bars or strips. Or could I use a cheap pewter toy or
casting for a zinc source?

Sometimes I wonder why I come up with such silly ideas. On my way
home I stopped off at the Big Orange Box hardware store and bought a
few things, and I saw an 8-pack of AAA cells, with 2 extra cells, for
under five bucks. So I bought the pack of ten for less than 50 cents
a battery. And here I'm trying to build something that will give me
less voltage and power, yet cost me lots more time and money. Duh.

Maybe it's the survivalist in me. The need to know how to create a
battery from scratch, just in case the situation gets as bad as it did
on the east coast before hurricane Isabel, where all the batteries had
been bought up for the emergency and people were left with nothing but
their wits.

But how do you go about separating the zinc inside from the copper
cladding? This brings to mind an episode that occurred to some
friends and myself a long time ago.

The guy I worked for got a bottle of Eastman 910 adhesive known today
as CA, cyanoacrylate or crazy glue or super glue. This was back when
it first came out in the mid '60s, and no one knew what it could do.

So the other guy in the shop says hold your finger out, and he puts a
small drop of it on my finger and tells me to squeeze my finger and
thumb together and count to ten. I did that, and Oh, Sh!t! I
couldn't get my fingers apart!

After dealing with that, by using a knife and losing part of my
fingerprint, we decided to win some coin-tossing bets. We superglued
some quarters, tails facing out, onto a piece of metal and chucked
them in a lathe and turned them down to half thicknes. We heated up
the metal with a propane torch to melt the glue and let the half
quarters loose. Then we superglued two quarter halves together and
clamped them in a vise. A few hours later we had a quarter that would
allow us to flip a coin and never lose!

When we turned down the coins, we found that some were really crappy
inside, like they had not been sintered together properly and the
metal was coming apart in small pieces. So the U.S. Mint's QC wasn't
all that great. Maybe that's still normal, maybe minting a coin out
of a sandwich of metals doesn't need to be done well, just around the
edges. I've never seen a coin come apart under normal circumstances.

Two problems. The coating is thin, so it may last only a short time.
And how to deal with the edges, where the steel is exposed and would
corrode.

(snips)

Been awhile since I did it, but I seem to remember nitric acid does a
pretty fair number on the copper while leaving the zinc behind. And
hydrochloric for the zinc leaving the copper behind (after filing away
the edges, so the acid can react with the zinc).

Anyhow search on the net using <"copper clad" "nitric acid" penny>

Probably just as easy to find zinc bars on line.

Then you'd have to melt them down and cast them. That takes 419
Degrees C. Charcoal and a blower with a crucible made from galvanized
pipe would work.

I used the iron pipe nipple / end cap crucible to melt aluminum at
~700 degrees successfully. The trick is to keep the hot gases (carbon
monoxide, and carbon dioxide) around the crucible so the metal doesn't
catch fire or oxidize. For molds I used dry hardened clay. I made
some fishing lures.

1083 C to melt copper. 1500 for iron - so the pipe crucible might
still work.

Interesting project.

Another source, from a building/appliance outlet, are the zincs they
make for water heaters. Hard to find because people would rather
change the heater than replace the zincs. (not many people know there
are zincs in water heaters)

Yeah, I guess I should replace the rods in my water heater every
couple of years. The heater is in a closet in the basement and is a
real pain to replace, not to mention the cold showers for a couple of
days. I think hot water is the basis of civilization.

Meh. Fold some sheet metal into a shape that can hold something without
leaking, then melt on the stove. It's not really hot enough to need much
for insulation.

For a mold, a metal plate would work well. If you really want to get into
it, a sand mold of a nice flat plate would allow very consistent results.

You should be able to buy it from a building supply company like
Lowes or home depot. THey sell Zinc to put on the ridge cap to kill
fungus that destroys asphalt shingles.

Galvanized sreel will work as well - the galvanizing is zinc.

Two problems. The coating is thin, so it may last only a short time.
And how to deal with the edges, where the steel is exposed and would
corrode.
Thanks.

Eh, minor details ;-)

Then you'd have to melt them down and cast them. That takes 419
Degrees C. Charcoal and a blower with a crucible made from galvanized
pipe would work.

Meh. Fold some sheet metal into a shape that can hold something without
leaking, then melt on the stove. It's not really hot enough to need much
for insulation.

For a mold, a metal plate would work well. If you really want to get into
it, a sand mold of a nice flat plate would allow very consistent results.

The fact that an aluminum pot will melt on a stove supports your
assertion. I had no luck melting aluminum in a cast iron pot (on the
stove) and had no luck melting aluminum in an iron crucible inside a
1200 watt radiant heating element. The charcoal was a whole differnt
experience. I never tried it stove-top.

Have you done it? What did you use? and how did it work?

Any problems with oxidation?

Don't know if you are in a likely area or not, but if you are in a major
metropolitan area you may be able to get zinc from a pipe organ
builder/repair firm. Many of the large pipes are made of zinc with a lacquer
finish. Smaller pipes are various tin alloys, but most such places should
have some old zinc sheet or old zinc pipes laying around.

I saw this http://home.t-online.de/home/gollum/salt.htm and I said,
why bother with a half volt when I could make one with a volt or two.
I could build a crow's foot battery like back in old the days of
telegraphy.

I got some root killer for the stump I'm still trying to kill; it's
mostly copper sulfate blue crystals. I have some copper plate around
somewhere, or I could use a piece of PC board. But where do I get
some zinc? http://metals.about.com/cs/zinc/

Thanks for the info. I guess I shoulda kinda said where do I get zinc
locally? There are welding supply shops locally, I wonder if they
have zinc in bars or strips. Or could I use a cheap pewter toy or
casting for a zinc source?

Sometimes I wonder why I come up with such silly ideas. On my way
home I stopped off at the Big Orange Box hardware store and bought a
few things, and I saw an 8-pack of AAA cells, with 2 extra cells, for
under five bucks. So I bought the pack of ten for less than 50 cents
a battery. And here I'm trying to build something that will give me
less voltage and power, yet cost me lots more time and money. Duh.

Maybe it's the survivalist in me. The need to know how to create a
battery from scratch, just in case the situation gets as bad as it did
on the east coast before hurricane Isabel, where all the batteries had
been bought up for the emergency and people were left with nothing but
their wits.

To make a crows foot? I remember that my dad's drinking
buddy used a zinc sacrificial anode on his sailboat to keep the rest
of the boat from corroding.

This battery sounds so cool.

Whatever you call the thing that makes you come up with what
you call "silly" ideas - that's the very thing that drives the
advancement of science.
