Coal Fire Turns Australian Mine Into Mordor’s Mount Doom

Coal Fire Turns Australian Mine Into Mordor’s Mount Doom.


fire at the the Hazelwood open-cut coal mine has turned a large swathe of Morwell, Australia into something out of J.R.R. Tolkien’s Mordor.

The fire at the mine has been blazing for three weeks and is believed to be the result of a bushfire started by an arsonist. The town of Morwell and its 14,000 inhabitants has been blanketed in smoke and authorities fear it could take months to completely extinguish the blaze. The town is about 150 km east of Melbourne.

There is speculation that the government of the province of Victoria may soon order a total evacuationTens of thousands of gas masks have been distributed, according to Vice.

The blaze poses a difficult challenge for firefighters because even when flames are extinguished the coal continues to smoulder. The fire can reignite at any moment and rages underground. Firefighters are concerned about the danger posed by landslides caused by the huge quantity of water being used on the flames.

Introduction to Bow-Drill

When you are first learning bow-drill fire-making, you must make conditions and your bow drill set such that the chance of getting a coal is the greatest. If you do not know the feeling of a coal beginning to be born then you will never be able to master the more difficult scenarios. For this it is best to choose the “easiest woods” and practice using the set in a sheltered location such as a garage or basement, etc. Remember to unplug your smoke alarms!

Wood Selection

Even if you have never gotten a coal before, it is best to get the wood from the forest yourself. Getting it from a lumber yard is easy but you learn very little. Also, getting wood from natural sources ensures you do not accidentally get pressure-treated wood which, when caused to smoulder, is highly toxic.

Here are some good woods for learning with (and good for actual survival use too):

  • Eastern White Cedar
  • Staghorn Sumac
  • Most Willows
  • Balsam Fir
  • Aspens and Poplars
  • Basswood
  • Spruces

There are many more. These are centered more on the northeastern forest communities of North America. A good tree identification book will help you determine potential fire-making woods. Also, make it a common practice to feel and carve different woods when you are in the bush. A good way to get good wood for learning on is to find a recently fallen branch or trunk that is relatively straight and of about wrist thickness or bigger. Cut it with a saw. It is best if the wood has recently fallen off the tree. Willow and aspen often break off limbs, especially in ice storms. If no green wood can be found, then use solid dry wood. Cedar can often be found in pretty good condition as standing skeletons. Avoid sections of wood with lots of knots and wood with cracks in it (checks).

Once you have a good section of wood (the more, the better), split it in half with an axe (or knife) to let it dry. A branch the diameter of your fist and a couple of feet long is a good size to work with. You want to have lots of material to experiment with as you burn through boards and spindles. Let the wood dry for about a week in the sun if possible, longer in the shade. Now you can make your set.

A Note on Knives

Make sure you have a comfortable knife to work with as this will make things more enjoyable and safer. I suggest a light knife with a blade of about 1/16″ thickness. Thinner blades require less effort to be pushed through wood. Avoid knives with finger guards as these just get in the way. A relatively short blade (about 3″) is easier to work with. The handle shouldn’t have any sharp, boxy angles or uneven surfaces. Keep your knife sharp. Many knives will do. Mora knives form Sweden are very nice and inexpensive. Don’t hesitate to use the ground as a work surface for bracing the wood against. The more stable the wood you are carving is, the better.

The Mora-bladed knife. Easy to use, high quality blade steel, and inexpensive too!

Making the Set

There are five parts to the bow-drill set. The bow, the string, the spindle/drill, the board, and the handhold. The drill spins against the board on one end and is held vertically by the handhold at the other end. The drill is spun by the bow and string.

The following describes how to carve the components of a beginner set from a larger chunk of wood.

The Board:

Taking the once-split branch, cut it with a saw or whittle and snap it into a foot long length. Using an axe or a knife and baton (a short, sturdy branch for hitting the back of knife blades) combination, split the branch evenly down the middle. Keep splitting until you get a flat board that is about one inch thick, or the thickness of your thumb. Whittle it down to remove any protrusions so you end up with a flat, straight-sided rectangular shape (this isn’t very important). The board should be about three inches wide, but anything greater than two inches is fine.

The Spindle:

Take a foot-long straight-grained section of wood (if possible, from one of your previous splits) and whittle it into a slightly less than one-inch diameter straight dowel. In other words, the dowel should have the same diameter as the first knuckle of your thumb. Whittle the last inch of each end into sharp points. The fatter the spindle, the less wear it places on the string, but a longer bow is required to result in the same amount of rotations taken per bow stroke. Essentially, this works the same way as the gearing on a bicycle.

The Handhold:

Take the other half-split branch and saw off a section approximately four to five inches long. Whittle down the edges to remove any rough spots and to provide a comfortable surface for gripping. On the flat side of this, exactly in the center from all four sides, gouge a hole with the point of your knife. Make the hole about half an inch deep. Make the sides of the hole slope out at a 45 degree angle so as to form a cone shaped depression.

The String:

There are a wide variety of materials strings can be made of. These include: nylon, cotton, jute, leather, rawhide, buckskin, and a wide variety of wild plants. In general, use a string that is at least one and a half times the length of your bow. The string should be relatively thick. A thickness of a quarter-inch will last a long time. Shoelaces are usually not thick enough for repeated use. Cotton hockey skate laces will do. It is best to avoid synthetics such as nylon as they sometimes melt from the friction unless thick enough. Thick cotton cord is just about ideal for repeated use.

The Bow:

Find a section of a green (live) branch that is about the thickness of your index finger and almost straight or slightly curved and the length of your arm from elbow to fingertip. The bow should be reasonably flexible but not flimsy. It should not want to bend more than two inches from a straight line when flexed using a little strength. If it bends too easily or is prone to snapping, find a slightly thicker branch or use a denser wood. If it hardly bends at all then you can carefully whittle off a little wood on the inside of the curve. Make sure it bends evenly to avoid weak spots. The flexibility of the bow is important in the overall feel of the set. If the bow doesn’t bend, the string will slip frequently and soon break. If the bow is too flexible the string will also slip and you won’t be able to apply the torque that is required.

Split the first two inches of each end of the bow with a knife. This is why you need a green branch. A dry branch will not split properly. Make sure the split is even and doesn’t run off to the side. The orientation of the split is very important if the bow has any curve.. When the bow is set on a flat surface, the splits should be parallel to that surface. Take two short lengths of cordage and snugly tie them around halfway up the splits. Use square knots of some other knot that will not work loose.

The clove hitch is very good for this. Tie one end of the bowstring into a knot. Set this end into the split in the bow so the knot is on the side of the bow that is curving away from itself (convex). Make sure that the string is held tightly by the split by moving the short section of cordage up the split toward the bowstring. This will effectively tighten the split. Take the other end of the bowstring and repeat on the other side. The amount of slack in the string is something that must be adjusted through trial and error when you fit the spindle. For now the string should be somewhat loose or you won’t be able to load the spindle.

Technique & Form

If you are right-handed, hold the bow with this hand. Place the board flat on the ground so it is stable. Take your spindle and push the point into the board so that you make a mark. This mark should be about one full spindle width from the edge of the board (about an inch). It should also be at one end of the board so that you have room to place your foot. With your knife, gouge a shallow hole similar to the one in the handhold.

The bow is tilted slightly down to avoid rubbing the string against itself. Also, the stabilizing of the left hand against the shin is very important.

Now, put your left foot on the board (if you are right-handed) so the inside ball of your foot is next to the shallow gouge. Your right knee should be on the ground and you should be sitting on your right foot. Your right leg should be parallel to the board. Another possibility is to raise your butt off your foot and lean your chest on your left knee -use whatever works for you.

Load the spindle by wrapping the string around the spindle so that the spindle is outside of the bow. This may require some adjusting of the string. The spindle should feel like it’s going to pop out. The tighter the string becomes, the better, just don’t make it so tight that it breaks the bow. Holding the loaded spindle and bow in your right hand, place the bottom point of the spindle into the hole in the board. Cap the other end with the handhold and apply some pressure to keep the spindle from popping out. Let go of the bow. The bow should be pointing itself up towards you. If it is pointing down, reload the spindle so the bow is pointing up.

Make sure the spindle is on the opposite side of the string to the bow. Otherwise the spindle will knock against the bow while stroking.

Burning In

You can now begin the “burn-in” process. This is to form the handhold hole. Simply begin stroking the bow back and forth slowly. Keep the pressure on the handhold fairly high. Eventually, you should see a small amount a smoke forming at one or both ends of the spindle. Pick up a little bit of speed until both ends are smoking. It is most important that the handhold end smoke at this point. If it refuses to, even when you pick up the speed and push down harder, reload the spindle so the top is now the bottom and vice versa. Repeat until the handhold starts to smoke. Keep going until the hole in the handhold is the same diameter as the drill. It should match the curve of the drill point exactly now.

Now you must lubricate this end (keep track of which end is up and which is down!) This is to keep it from smoking and taking away your energy so all your power can be focused on the lower end. Unload the spindle and rub the top into the hole in the handhold. Blow off any dust. Push the drill into the handhold as hard as you can and slowly rotate the drill. Again, blow off any dust. Now, rub this end into your hair and along the sides of your nose. This is to transfer the natural oils found on your skin onto the wood. It helps if you haven’t showered for a day.

Repeat the pushing-in procedure. You may want to push the end of the spindle against a smooth rock. This effectively hardens the end of the spindle by compressing the wood. To baseball players, this is known as “boning”. Repeat the pressing of the spindle into the handhold hole and rubbing the tip into your hair until it develops a sheen. Keep all moisture away from this as it will cause the wood to expand and it will bind in the handhold causing friction and burning. You want the frictionless end of the spindle to be very rounded. This distributes the pressure forces over a greater area reducing the tendency of the spindle to drill up into the handhold. If you imagine an electric drill, a small bit will require less effort to drill through a material than a very large one. We want to prevent the drill from burning at this end so we use a large surface area.

Cutting the Notch

You must now make a notch in the board next to the “burned-in” hole so the ground-off powder has a place to accumulate. Take your knife and scribe a 45 degree angle in the top of the board that originates form the center of the hole. The two lines will go to the closest edge of the board. Cut out the wood in between these lines so that you have removed about a one-eighth fraction of the burned-in hole. This slice should go all the way to the bottom of the board so that you have removed a wedge of wood on one side of the board pointing to the center of the drill hole.

Getting the Coal

Place something under the board where the notch is to catch the coal. This can be paper, birch bark, etc. If you are on a floor, the coal will melt it so keep that in mind. Put yourself into the position explained earlier and begin drilling. Be sure to put the lubricated end of the drill in the handhold. You can now begin the first stage, “powder”. Drill slowly and with firm pressure until the bottom end begins smoking. Keep the smoke down to just a wisp. You should see powder accumulating in the notch. Keep this slow pace until the notch is just about filled. Now lighten the pressure and drill very fast. This is the “heat” stage. The idea is to make heat, not powder. It should begin to smoke heavily. If not, apply a bit more pressure until it does. Keep going until you are totally surrounded by smoke. At this point, stop drilling and carefully remove the drill. If there is smoke coming from the powder pile for more than a few seconds you probably have a coal. Gently blow on the coal until it begins to glow red. You may now transfer it to a tinder bundle. This is simply a fist-sized bundle of dry grasses, fibrous inner bark of certain trees, etc. Blow on it until it flames up.

Sometimes you can skip the powder stage and just go for the heat. This is usually when the wood is very dry, soft, and easy to work with. Every piece of wood is different, even from the same tree.

Reading the Powder

If the drill begins smoking in the handhold end you will have to re-lubricate it. You may have to switch the ends of the spindle as one end may be slightly harder than the other. Another solution is to “shoulder” the lower end of the spindle. This is simply reducing the diameter of the last inch or so of the drill. This results in less pressure being needed to drill the spindle into the board. This often solves the problem of the handhold burning as well as the problem of the lower end of the spindle refusing to start burning. Problems can often be solved by looking at the colour and consistency of the powder.

Remember, the suggestions below are for the powder stage. The heat stage should produce the least amount of powder with the most amount of heat. In other words, you should be pushing down enough only to make lots of smoke, but no more powder. If you push down too much you run the risk of making crusty powder and pushing all the good powder you so carefully made out of the notch. This is not so important with dry, soft woods, but is very important when using damp or slightly harder than ideal woods.

Colour Consistency Problem
Light Brown Dusty Going too slow, not pushing down hard enough
Light Brown Fuzzy Going too slowly
Dark Brown/Black Fuzzy Perfect
Dark Brown/Black Little Rolls Difficult, sometimes going too fast & not pushing down enough
Dark Brown/Black Crusty Pushing down too hard, going too fast
(see photos below for examples of each type)
Colour is associated with speed. Light brown means there is not enough heat being generated, hence you must drill faster. Black means there is plenty of heat generated although you have to be careful not to push too hard. Consistency is associated with downward pressure. Dusty means tiny floury fragments are being ground off. This isn’t so much of a problem in itself, but it usually occurs because there is not enough pressure down and not enough speed. Fuzzy is perfect. This provides the most amount of surface area for combustion to take place. Crusty means there is too much pressure down. This usually occurs in combination with too much speed. This powder will not ignite easily because there is little surface area for combustion reactions to take place.

Light brown, dusty powder

Light brown, fuzzy powder

Dark brown/black, fuzzy:
Perfect powder

Dark brown/black, little rolls

Dark brown/black, crusty

This will usually allow you to adjust your technique and get a coal. Sometimes however, this isn’t possible. For instance, if you are pushing down as much as you can and still getting dusty powder or hardly any powder at all you have done all you can with technique. Your next option is to shoulder the spindle down a little more as was mentioned before. This way the set will require less downward pressure to produce more powder allowing you to fill the notch with the same amount of strength. A downside of this is that the set becomes more sensitive making it easier to push too hard!

If the problem seems to be not enough speed, there are a couple things you can do. First, you could make another spindle this time a little wider. The wider spindle will generate more heat because the edges of the drill will be traveling faster than the narrower spindle. The second option and probably better is to use a longer bow. This may or may not be of help, depending on how long your bow already is. This allows you to reach higher speeds by taking longer strokes, resulting in less time spent stopping and starting the bow.

Finally, there is the problem of getting powder in the form of little rolls. These look like the rolls you would get after using an eraser. Sometimes these happen because the wood is somewhat damp. Other times, you get these when the wood is a little hard. The best way to approach this, in my experience, is to shoulder the spindle down a bit, build up a good pile of powder (whatever it looks like), and just try to make as much heat and smoke as you can. Usually this results in a coal, but if you are already tired it can be very difficult. (See photo below)


It is very important that the fundamentals are learned before attempting the more advanced techniques. If you don’t learn how to read what the wood is telling you, your coal-producing reliability will be unpredictable in the more difficult scenarios. You should be able to get a coal nearly every time you try when using a proven set before you move onto made-from-scratch bow-drills. Keeping a notebook of your experiences and experiments will greatly aid in advancing your ability.

Presidential Palace In Bosnia Set On Fire As Riots Break Out Protesting 40% Unemployment | Zero Hedge

Presidential Palace In Bosnia Set On Fire As Riots Break Out Protesting 40% Unemployment | Zero Hedge.

Another day, another European nation is hit by violent riots as protests over the economy and corruption spilled over violently into the street, this time Bosnia where more than 150 people were wounded on Friday in the worst civil unrest in the country since the 1992-95 war. The reason: anger over the dire state of domestic politics, the economic collapse and especially the country’s 40% unemployment rate. The Telegraph reports that angry protesters set fire to part of the presidential palace in Sarajevo, as well as government buildings in the capital Sarajevo, Tuzla and Zenica. At least 80 people were injured in Sarajevo and 10 in Zenica, authorities said. There were no immediate casualty figures from Tuzla, where the worst of the fighting was.

Bosnia is a relatively new entrant to the current iteration of mass protests, however judging by the severity of public anger, the country is doing its best to catch up with the rest of Europe. More:

Demonstrators also clashed with riot police for a third consecutive day in the protests, which have remained largely contained to the Croat-Muslim Bosniak half of Bosnia.

Anti-government protests began on Wednesday in the northern city of Tuzla, before spreading as thousands took to the streets of a dozen cities to express their discontent over the almost 40 per cent unemployment rate.

Local media said police used rubber bullets and tear gas to disperse protesters in Sarajevo, where demonstrators stormed two government buildings including a presidential office, setting them ablaze and smashing furniture. The palace fires were promptly put out but almost all the windows were broken.

By 7pm local time, protesters had dispersed in the three main flashpoint towns, but police remained out in force. All shops were closed and streets were littered with glass and debris. On Saturday morning, the streets of Sarajevo were calm after firemen spent the night dousing the flames which almost gutted one regional government building, consuming cars and newsstands nearby.

However the city was bracing itself for further protests.

In Tuzla, the crowd stormed the local government building, throwing furniture, files and papers out of the windows and then setting the building on fire.

The protests in Tuzla may be calming following the resignation of Sead ?ausevi?, the Prime Minister of Tuzla Canton – one of 10 cantons in the Croat-Muslim Bosniak half of Bosnia – but other cities are only just getting beginning. In an unprecedented move, hundreds gathered in the capital of the Bosnian Serb part of the country, Banja Luka, to express support for protesters in the country’s other mini-state, which is shared by Bosniaks and Croats.

“We gathered to support the protests in Tuzla where people are fighting for their rights,” said Aleksandar Zolja, an activist from Banja Luka. The protests began on Wednesday with a clash between police and unpaid workers of four former state-owned companies, which left some 130 hurt, mostly from tear gas.

Said otherwise, wealth transfer, crony capitalism, corruption and an economic collapse have managed to unite the same people that just two decades ago were killing each other during the Yugoslavian civil war over such typical Eastern European lines of tension as religion and ethnicity. Congratulations.

Four companies employed most of the population of Tuzla. When they were privatised, contracts obliged the new owners to invest in them and make them profitable but they sold the assets, stopped paying workers and filed for bankruptcy.

Ironically, the very same is happening in the US and the rest of the world, as the productive assets are being confiscated, the middle class is being exterminated, and an increasingly smaller number of entities control the bulk of the wealth.

Summarizing the Bosnian situation in a nutshell:

Beside the high unemployment rate, the privatisation that followed the end of communism and the 1992-95 war produced a handful of tycoons, almost wiped out the middle class and sent the working class into poverty. Corruption is widespread and high taxes to fund a bloated public sector eat away at paychecks.

Or yet another teaser of what is coming to every other insolvent, crony capitalist, corrupt country in the world.

Argentine Banking System Archives Destroyed By Deadly Fire | Zero Hedge

Argentine Banking System Archives Destroyed By Deadly Fire | Zero Hedge.

While we are sure it is a very sad coincidence, on the day when Argentina decrees limits on the FX positions banks can hold and the Argentine Central Bank’s reserves accounting is questioned publically, a massive fire – killing 9 people – has destroyed a warehouse archiving banking system documents. As The Washington Post reports, the fire at the Iron Mountain warehouse (which purportedly had multiple protections against fire, including advanced systems that can detect and quench flames without damaging important documents) took hours to control and the sprawling building appeared to be ruined. The cause of the fire wasn’t immediately clear – though we suggest smelling Fernandez’ hands…


We noted yesterday that there are major questions over Argentina’s reserve honesty

While first print is preliminary and subject to revision, the size of recent discrepancies have no precedent. This suggest that the government may be attempting to manage expectations by temporarily fudging the “estimate ” of reserve numbers (first print) while not compromising “actual” final reported numbers. If this is so, it is a dangerous game to play and one likely to back-fire.

During a balance of payments crisis – as Argentina is undergoing – such manipulation of official statistics (and one so critical for market sentiment) is detrimental to the needed confidence building around the transition in the FX regime.

And today the government decrees limits on FX holdings for the banks

Argentina’s central bank published resolution late yday on website limiting fx position for banks to 30% of assets.

Banks will have to limit fx futures contracts to 10% of assets: resolution

Banks must comply with resolution by April 30

And then this happens…

Via WaPo,

Nine first-responders were killed, seven others injured and two were missing as they battled a fire of unknown origin that destroyed an archive of bank documents in Argentina’s capital on Wednesday.

The fire at the Iron Mountain warehouse took hours to control…

The destroyed archives included documents stored for Argentina’s banking industry, said Buenos Aires security minister Guillermo Montenegro.

The cause of the fire wasn’t immediately clear.


Boston-based Iron Mountain manages, stores and protects information for more than 156,000 companies and organizations in 36 countries. Its Argentina subsidiary advertises that itsfacilities have multiple protections against fire, including advanced systems that can detect and quench flames without damaging important documents.



“There are cameras in the area, and these videos will be added to the judicial investigation, to clear up the motive of the fire and collapse,” Montenegro told the Diarios y Noticias agency.
