"The bowstring wood drilling method requires several pieces of wood, a drill shaft, a drill board, a backing board, a stick in hand, a length of rope and the most important tinder to make a kindling, and then use a knife or other sharp tools
Process these raw materials.”
Bi Fang put on his spare brown robe and searched around in the bushes. He picked up a branch and pinched the hardness with his nails, but found that it didn't fit.
"The principles of the bowstring method and the hand drill method are the same, but the structure is slightly more complicated. Part of the labor is replaced by instruments, and elastic potential energy is converted into kinetic energy in exchange for higher efficiency. Therefore, in terms of material selection, it is different from the hand drill method.
It’s almost the same, so I won’t go into details here.”
Walking through the bushes, Bifang quickly found a suitable drill shaft. It was a small bush with a bunch of small red grapes growing on its branches.
It may be that the fruits have taken a long time to bear fruit and look wrinkled.
Bi Fang stretched out his hand to break off a branch and cut it with a whaling harpoon.
"I used burdock last time, we can use it this time, elderberry."
【Elderberry? Sounds familiar.】
[I know, it’s Master Dumbledore’s Elder Wand!]
[Excuse me, can this elderberry of yours be used to make a wand? (Funny)]
[Damn, when you mentioned it like that, I remembered that feelings are the material of the Elder Wand, which is elderberry!]
[Can this fruit be eaten? It feels very similar to the Yagda in Mohe]
Bi Fang knew everyone was joking and joked.
"That may disappoint everyone. I don't know how to make a magic wand, I can only make a drill shaft. Elderberry is soft in the middle, but the pole is harder and has pith, which can produce more and larger sparks than the burdock last time.
It also needs to be suitable.”
"As for the fruits." Bi Fang stretched out his hand to help him up. "The ripening period of elderberries is between September and October. These are already rotten, and even if they are not rotten, we can't eat them because elderberries contain a glycoside.
This substance is a raw material used to make cyanide and we cannot eat it directly."
The audience was greatly disappointed, thinking that the fruit was similar to the one in Mohe.
It was easy to find wood in the woods. It didn't take long for Bifang to find all the materials. On the other side, Etienne also dug a pit as required.
Bi Fang touched the stones in the pit, nodded with satisfaction, and explained in French why stones were laid in the pit.
"Because of the geese and gliders, we can't go too far from the river bank, which makes the soil nearby relatively moist. We must choose a dry place to light the fire, so that the fire can be easily lit and spread at the bottom of the fire pit.
That’s what the stone does.”
"We must use dry stones here. Wet stones, especially stones from riverbeds or valley bottoms, must not be used. Such stones will produce steam when heated, which can cause an explosion. It is very dangerous. It doesn't matter if you can't find completely dry stones.
Just remember not to use stones that have been soaked in water."
【Thin, too thin.】
[Learned another small detail]
【Excuse me, are you polite about this?】
With the materials in hand, Bifang started processing.
"The length of the drill shaft should be at least as long as the distance from the tip of your thumb to the tip of your index finger when you open your hand. This makes it easier to operate. Then sharpen the top and make the whole thing round and smooth."
"The width of the drill plate should be more than twice the thickness. It should be easy to step on and keep stable. The thickness of the backing plate should also be greater than the diameter of the drill shaft."
"The stick in your hand, that is, the fire bow, should be slightly curved. A straight stick can also be used, but it is best to have a certain degree of curvature. In short, the whole thing must be easy for you to operate."
"As for the rope, we can just use shoelaces. If the shoes you are wearing don't have shoelaces, you can make a temporary one out of tree fiber."
After preparing all the materials, Bifang made a slit at one end of the drill board, gouged out a small hole, and gathered the fine scraps scraped from the coniferous trees into it to serve as tinder.
Then he dug a small hole at one end of the backing board, stuck the main drill shaft, tied the rope to both ends of the stick, and wound the drill shaft around the rope, making a cross between the wooden stick and the drill shaft.
"We must work hard to control the tightness of the rope. It can neither be so loose that the drill shaft slides up and down, nor so tight that the drill shaft cannot move. The ideal state is that the drill shaft can be forced to twitch after applying a certain amount of force.
.”
Etienne looked on in amazement and couldn't help but ask: "How many ways do you have to make a fire in the wild?"
"Haha, I really haven't counted this." Bi Fang raised his head and thought about it carefully, "There are probably seven or eight different ways to make fire in different environments."
"So many?" Etienne said in shock.
"Actually, there are not many. There are only a few that can be used in different environments." Bifang shook his head and looked at Etienne, "What, you want to learn?"
Etienne nodded.
"If you want to learn, I can teach you when you get back." Bi Fang smiled and then started to light a fire.
He stuck the drill shaft in the hole of the drill plate, inserted the tail into the small hole in the backing plate, stepped on the drill plate with his left foot, knelt with his right leg on the ground, held down the backing plate with his left hand to control the pressure of the drill spindle, and started to stabilize with his right hand.
And move the fire bow back and forth powerfully.
Soon, smoke began to emit from the drill board, and many spectators were in an uproar.
[This is very efficient and much more convenient than a hand drill]
[It’s fast, but I feel so complicated and can’t remember it...]
【Me too.】
Etienne was very excited when he saw the smoke coming out, but Bifang did not stop, but continued to pull the fire bow. It was not until seven or eight minutes later that the smoke turned out to be bigger, and there was even a flash of red fire, and he finally
Stop drawing the bow.
Carefully take out the drill shaft. At this time, there is already charcoal fire on the drill plate.
Bi Fang carefully moved the charcoal fire to the prepared fire starter and blew it gently. Soon, a small flame ignited and the entire fire starter was wrapped in flames.
【Awesome!】
[Zeng Hang presented meatballs*1000 to the anchor—too fast, Lao Fang was too fast!]
【Excellent efficiency】
"call!"
Bifang breathed a sigh of relief, and Etienne quickly threw the dead branches into the fire pit, and the flames quickly grew bigger.
After squeezing the soaked clothes dry and putting them on the fire to bake, Bi Fang sat by the fire and felt the long-lost warmth, feeling much more comfortable.
"The bow drilling method is very convenient, but there are too many details, so it is difficult for people who are not familiar with it to succeed. It is not suitable for novices."
"Just like the tightness of the rope also determines the flexibility of the bow. During use, the length of the string may need to be adjusted. For convenience, when binding the rope, we must tie a dead knot at one end and a loose knot at the other end."
"You can also use some grease to increase lubrication when drilling holes, so I specially used tinder from coniferous trees, which is rich in grease."
It was these little details that made this fire-making such a success.
Etienne continued to dig holes aside, preparing to burn two more fire pits so that the clothes would have a larger area to bake and dry faster.
He doesn't know how to survive in the wilderness, so he can only help with these small things and try not to hold him back.
Etienne had just finished hanging a piece of clothing when suddenly, there was a strange noise.
