I want to send a 95/5 percent mix of 02 and propane down a tube underground
into gopher burrows. I will have a piezo sparker at the end of the tube
back a bit so it doesn't get plugged up with dirt. Perhaps inside a phallus
shaped protective head with many drilled holes. I'm thinking of something
flexible for the hose. Inside that, I have to run the two wires to the
piezo. I might be able to run one, and use the hose as a ground if it is
made of metal, like a smog sensor hose. Piezos on barbecues have one wire.

My question is: Is there wire that has coatings that are resistant to high
temperatures? I know there are lots of such wires in stoves, but most I
have seen look ratty from use. There would be a flash and explosion, but no
terribly high temperatures for a very long period of time, as all the oxygen
would be consumed in the explosion.

What would such wire be called, and where do I get some?

Thanks. My Gopher Getter is moving along now that I'm getting some of these
other projects out of the pipeline. I hope to be ready by gopher time in
spring.

Try teflon coated wire. It should last a long time in this
situation. The peak temp will be much higher than the wire rating,
but it probably won't last long enough to damage the wire. Here is
one source: http://www.weicowire.com/wirecablecontents.htm
PS...better have a good flame arrestor/backflow preventer on the
supply tube to prevent a major backfire in the tube, regulator, tanks
etc. Propane/O2 burns with a nasty bang.

You can get high temperature wire at an appliance parts store, but I don't
see
why you would need it (it is kind of expensive...). While an oxy/propane
flame
is certainly hot enough to melt most kinds of insulation, the duration of
the
flame in your application is so brief that the wire shouldn't even get warm.
I would say that wire insulated with PVC (common) or, better yet, Teflon
(less common, used as hook-up wire in aerospace applications, readily
available from electronic surplus stores) would be more than adequate.

Steve,
You might just consider automotive sparkplug wire, should be available
at auto parts store, by the foot. It's good for relatively high
temps, (not flame) but the insulation is very thick, so it should last
a relatively long time.
Second source is Omega temperature products. High temp thermocouple
wire will take the temp, but maybe not the high voltage.

Are you measuring your gas flows?

I don't know what a "McGiver type" would do, but I can give you a tested
"Larry Moe and Curly" method.
From the uphill-most hole, feed in an oxy-acetylene mix. After a while, put
away the torch, and using a slingshot, fire balls of burning masking tape at
the hole from about 30 feet or more depending on skill level. In the spring
you can fill in all the trenches.

A local service uses small gas engines mounted on frames with an exhaust tip
below base level to kill gophers. The exhaust tip is placed in a hole, and
they use 6 or so engines. By the time they run out of fuel, the varmints are
all Auschwitzed. A friend did the same using his old Jeep and a piece of
flexible metal tubing. He let it idle for 3 hours, and no more gophers.

Rather than a piezio, why not just a spark plug? Either a coil and
battery or a lawn mower magneto would make it go boom, and every junk yard
around has tons of them.

One wire mounted inside a grounded tube, or two wires running to the spark
plug you set into the hole before you pump in the gas.

I'd put a flame suppressor near the bottom. A Davy miner's lamp uses
wire gauze, you might need something more substantial like a steel
disc with a lot of small holes drilled in it. Flame won't propagate
past such a structure, and it'll also attenuate a pressure pulse.
Keeping the boom out of your tube might be a good thing.

I'd then use a ceramic insulator with a thru electrode to introduce
spark on the other side of the flame suppressor. McGiver solution: a
sparkplug.

There are also kanthal rods with ceramic insulators used as spark
furnace ignitors. Check with an HVAC supply place. Honeywell and
others make them. They have considerably longer electrodes than a
sparkplug.

I hate moles. I've tried CO, a variety of explosives, traps, water,
and even country westerm music.

One Saturday afternoon I noticed mole acivity around my daughter's
above ground pool where the water splashes out, attracts worms, and
thence attracts moles who feed on the worms. My daughter's friends
suggested blasting them out with heavy metal music (metal content).
These are urban moles so I thought country/western music might be more
effective.

I excavated to a plenum/manifold feeding several runs and installed a
speaker mounted in a small cardboard box which I then burried and fed
with one channel from a boom box. Tuned it to a local 24 hour C/W
station, turned the volume to max and was able to hear the music
through out the network of runs. Over the next 24 hours I first
observed that they were sequentially plugging passages so I could no
longer hear the music on various runs. The next day I found the
speaker above ground, packed with dirt, still playing, and the hole
where it had been was recovered with earth. All in all, an
entertaining activity leading to no success. I watched the swimming
pool floor receed into the caved in mole runs.

More recently, at a new home with a perfect lawn and surrounded by an
old second-rowth douglas fir forest -- I renewed my efforts using
traps exclusively. This is very labor intensive and does almost as
much damage to the lawn as the moles themselves. After 3-years,and
perhaps a dozen moles in the trap, I gave to remainder the cratered
and channeled lawn to the moles.

Quite by accident, I susequently discovered that if you only water the
lawn enough to keep it alive, instead of lush, you do not bring a lot
of worms to the surface, and the near infinite supply of moles living
in the forest take little interest in the lawn.

That's my story and I'm sticking to it.

I want to send a 95/5 percent mix of 02 and propane down a tube underground
into gopher burrows. I will have a piezo sparker at the end of the tube
back a bit so it doesn't get plugged up with dirt. Perhaps inside a phallus
shaped protective head with many drilled holes. I'm thinking of something
flexible for the hose. Inside that, I have to run the two wires to the
piezo. I might be able to run one, and use the hose as a ground if it is
made of metal, like a smog sensor hose. Piezos on barbecues have one wire.

My question is: Is there wire that has coatings that are resistant to high
temperatures? I know there are lots of such wires in stoves, but most I
have seen look ratty from use. There would be a flash and explosion, but no
terribly high temperatures for a very long period of time, as all the oxygen
would be consumed in the explosion.

What would such wire be called, and where do I get some?

Thanks. My Gopher Getter is moving along now that I'm getting some of these
other projects out of the pipeline. I hope to be ready by gopher time in
spring.

I continue to wonder if a piezo sparker will work satisfactorily here.
The Rodenator used or uses somewhat higher energy ignition. It uses or
used 1 or 2 nine-volt batteries, may be more akin to a stun gun than
to a piezo sparker. Piezo produces a rather feeble spark that may
not like even 3 feet of wire between it and the spark gap, and your
lean 95-5 mix may require considerably more energy to ignite than the
near-stoichiometric mix found in a gas burner.

A McGiver solution might be to rig a firing pin setup that uses small
pistol primers. At about 2.5 cents per pop, the cost would be
considerably less than that of the oxygen going down the hole. A bit
of dirt might screw up a spark gap, while primer ignition would tend
to be self-cleaning.

Got it. Two copies actually, not sure how that happened but (shrug).
When I was in London about 15 years ago, there was a group of musicians
at the bottom of the escalators in Piccadilly Circus that did a great
job with the Dave Brubeck stuff. I wonder if they're still working that
fantastic location.

Another solution would be a rocket igniter, easily made by putting a
thin wire over a match head. The current heats the match head to
ignition and the flare up lights the gas (or rocket engine). They are
available commercially in hobby stores. ;)

So, if it's baroque, fix it, 'Arry. I prefer jazz/blues fusion.

Easy to make if one has time. I've made lots of them with kitchen
matches, strands from lampcord wire and dabs of clear nail polish.
I'll bet the squibs at hobby stores are a bit more than 2.5 cents a
pop.

We've had our differences in the past, Steve, but you just grew in stature,
at least in my eyes. I thrive on his music, particularly the old quartet,
which included Dave, piano, Paul Desmond (deceased) alto sax, Eugene Wright
(a true gentleman if there ever was one) string base and Joe Morello, drums.
You may know that this quartet was disbanded in '67.

By the way, the grand old gentleman turned 87 years old today----and he's
still touring, although on a limited basis. I've met and talked to him on
several occasions. He is, without a doubt, one of the finest human beings
I've ever encountered.

Certainly not Brubeck------but it does evoke memories of Johnny Cash, an
excellent performer, at least in my opinion.

Well, thank the French, who have provided us with the Jacques Loussier
Trio-----an experience that may never be rivaled by anyone.

And I won't soon forget the Modern Jazz Quartet.

There's some excellent music out there that doesn't require that you put you
brain in neutral.

As a kid, I'd use a single strand of copper wire and a low voltage high
amperage source ( I used to use an old tube type power supply from a radio,
but a 6 or 12 volt battery (think auto or garden tractor) would serve very
well). I'd pluck the single strand from something like appliance cord, then
hook it to heavier wire. No need for anything more, although a match head
would certainly provide insurance of ignition.

The single strand will glow red and burn in half, much like a fuse. I used
to fire home made cannon that way, using home made black powder. Worked
every time.

IIRC, the feds limited how much of that you can buy now.

The limit must be more than the 300' rolls I usually buy ;)

I guess I was a bit wrong. The above company has an injuction against them
