You will need
- Anvil, ferruginous sand (special black sand from the coast of Japan, which melted steel), hammer, foundry, charcoal, horn, powder Sandstone, water, clay, rice straw, as well as grinding and polishing tools for processing steel. If all you could find, then proceed to the manufacture of the sword.
Immerse the charcoal, light it, place the sand in a foundry and at a temperature of 1500 degrees, to melt, approximately four kilograms of steel. Divide the resulting metal on the low - and high-carbon steel. Mild steel – grey-black. Put on the bottom horn small and large pieces of charcoal, then ignite. Then place it into the horn high carbon steel and also sprinkle a bit of charcoal.
After that, spread on the bottom of the furnace ash from rice straw and pre-crushed charcoal, put a layer of high-carbon steel and pour it all in charcoal. Then begin to quickly pump the bellows until the forge won't be alone steel. Carefully remove the pieces of steel and start forging them from flat sheets. Keep the thickness they were no more than five millimeters. Divide steel into high – and low-carbon.
Pieces of high carbon steel put onto the steel billet with the handle, wrap in paper and apply the clay. Then, put it all into the horn and fill with charcoal. Warm about a half hour before the appearance of white color. The resulting block, remove, put on the anvil and hit several times with a hammer. Then again put into the furnace, well rascality and again hit a few times with a hammer. Repeat this procedure five or six times.
You get steel, which is called "cavagna". Take a mild steel that you have set aside, make of her bar by forging, and then turn and procuste it another 9-10 times. Now you got steel, singana".
The next step will be blank for the blade. Split the bar and forge from it a rectangular plate. Stretching the plate perpendicular to the length, you will give the blade the desired shape. Treat, file the shank of the blade. The process of making the katana, done in the following way. From a couple of sticks of wood to make the handle, you first wrap the skin, then a cord of cotton.
Attention! When working, observe the precautions! Work gloves in good light.
Do not start to make a katana until you prepare all the necessary components.
Advice 2: How to make charcoal
Charcoal is one of the products of combustion of wood. Black porous material which comprise carbon and hydrogen with a small amount of mineral impurities in the form of carbonates and oxides of various metals.
You will need
- - wood for turning into charcoal
- - firewood
- - iron tank
- - scoop
Charcoal obtained by thermal decomposition of wood without air supply. This process is called pyrolysis. Depending on the combustion conditions formed product with different properties. The main parameter influencing the quality of coal, is the temperature of pyrolysis.
By charring the wood bled of moisture and oxygen, leaving only combustible substances — carbon and hydrogen. Pyrometric indicators of the obtained product is increased compared to the starting material. To obtain the charcoal glow of the wood need to slowly, and the process temperature should be about 400°C. Rapid heating to high temperatures will lead to the formation of tar and volatile products of combustion.
To the charcoal can in the home, erecting the analogue furnaces for charcoal. For this fit the iron barrel with a sealed lid. Cook and firewood, and the wood intended for turning into charcoal. Install a barrel on a stand, for example, stones or bricks. Fill your improvised furnace for charcoal wood, previously cut into small bars. Tightly close the lid. Provide small holes for release of flammable gases. Put a flame under a barrel.
After a few hours, when holes cease to pass gas, heating can be stopped. But the barrel should not open until the complete cooling of the obtained coal without access of air. Otherwise, the combustion air may be resumed, and the coal is completely burned.
You can just burn wood in the stove or in the fire to produce red coals. Then collect the coal shovel in an iron container, tightly close and leave no air flow to cool down.
