Hey, Recurve Bows are more powerful because the extra bend on either end allows for more spring. You are no longer getting a bend from just the middle of the shaft; each end of the bow also bends. So basicallly, it's like having miniature bows on each end of your bow, but at lower draw weights. Because of that, the "bows" on the end reach their max draw weights (×2) before the actual main bend in the entire bow as a whole. This means the bow bends much farther, even though the actual distance the arrow travels remains the same.
Recap-
More spring from a bow on a bow = more potential energy with the same amount of space= more force.
I know that might be hard to follow since I am not using any technical terms, but hopefully that will explain why recurve bows are so nice.
Ye they have more smoothly running drawstring from the spindles aswell as the extra length in the drawstring paired with more leverage
As a Mongolian I can say that the composite bow has a very similar design as your bow. The bow is so powerful because you're forcing it to bend against it's natural curve. Otherwords, you are able to store up more energy or greater strain than normal long bows.

What about arrows? I know you can buy them now but what about the future? Seems all governments want unarmed citizens as they are easier to control or kill. Also easier for the criminals to get their way. The courts are useless and we need the death penalty to get rid of the troublemakers we are storing in prisons.
Murders, rapists and others that commit crimes are not citizens and should not have the right to vote, not ever. The crime stays with you for life.
+Mark Anthony Luckily with archery, it's a primitive tool. You can make an arrow with things you find laying around just as easily as the bow itself, especially in the woods. There's even good ones on this channel.
+Mark Anthony funny part is arrows will kill an armored target easyer then a bullet because how kevlar works. blade eat it like butter. but if thats a thing ugess we will all go back to breaking flent into arrow heads and gutting dear to make bow strings and picking feathers for fletching.
I hear that the Government want's to list butter knives as potential lethal weapons. They asume if it cuts food it belongs on a list you have to take a Government controlled safety course in before you can buy them. Forks are next.

Had the bow set up at a pro shop. It performed just fine ua-cam.com/users/postUgkxQEKUoxLWwayEDZR0NKB-5limn4MBU-2L . And I would say this is a good starting now that I could pass down to my son when he is older.But the package was missing the release and a nock was missing from one arrow.Dealing with customer support was terrible. They suggested I buy a new release rather than correct their own quality control issue because it’s to expensive for the. to ship it out from China.Update: manufacturer got back to me and resolved the issue. I retract the above statement.

because of it's shape, the ends of the recurve bow essentially act like a lever; this is where the extra power comes from
@Picogram I mean, you're wrong about saying that "the longbow" is the most powerful, and it's a self-contradiction, too. I mean, if the recurve bow is a force multiplier, then wouldn't a recurve bow of draw weight x always be better than longbow of draw weight x? And it's not like you can't get recurves as powerful as longbows - asiatic war bows were remarkably similar to English war bows - 80 pounds and up.
Because it's a Turkish bow!
No. The reason he's not getting more penetrating power out of the heavier bow is primarily because the heavier draw weight bow has more limb tip mass, so lots of the energy stored in the bow is expended accelerating the heavy limb tips rather than accelerating the arrow. Other factors that could be reducing the heavier draw weight bow's performance are things like having a stretchier string and having an arrow that isn't well tuned to the bow. An arrow that isn't spined properly to the bow's draw weight can result in more friction between the arrow and the bow, as well as something called arrow slap, which happens when an arrow that has undergone deformation during acceleration rebounds after it leaves the string, causing the arrow's tail to collide with the bow. Arrow slap robs the arrow of kinetic energy and causes it to fishtail as it flies down range, which bleeds speed and can also cause the arrow to strike the target at an angle rather than dead-on, which also results in less target penetration. You can actually hear arrow slap happening several times in this video, and it's least pronounced when he uses his subscriber bow, which means his subscriber bow is almost certainly the most efficient of the three.
@DevilTrigger Yeah what MegaAdeny said. Recurve bows are superior to long bows period. The myth of the English longbows almost legendary nature really reminds me of the exaggerated legends surrounding Japanese katana when it comes to swords. British longbows were excellent bows don't get me wrong, especially for European bows. More impressive than the British longbows is the archers themselves and the sheer amount of well trained men, that more than the bows themselves made the English archers a force to be reckoned with. To tie a nice bow on top of all this, go google image search the Marry Rose bows. A number of them found on the wreck are in fact, large recurve bows. So the English actually used large longbow sized recurves something that actually isn't super well known. Still credit where credit is due, Asians developed better bows, both composite and recurve they were cutting edge technology for the time.
Correct the Turks knew what they were doing.
Very informative. You are a very articulate young man. I'm 70 but never to old to learn. You'd make a good teacher. I'll being trying to make the bow you built in this video!

can you tell me alternates for driveway marker
Yep, that's exactly right! The recurve has a faster launch without needing the higher poundage. Recurve is great for tighter spaces that still need the strength of the shot. When the hunter is in amongst the trees and the hunted is in the open.
Aunt B
a little knowledge for you man.
the recurve in the bow increase the force of the bow, it can do more work for less pull basically. So you may ask why didnt every country have recurve bows. well some just didnt know how to. also its a complex thing to do with glue and layers of things like bone and specific wood. another is the glues were susceptible to weather. thats why when you see the mongols on horseback sometimes you see a long box attached to their horse. the box is used to keep the bow from being destroyed by the weather.
back before things like high tech alloys and plastics that we take for granted you couldnt have your cake and eat it too. :p
this is why the recurve had almost the same penetration as that bow you could hardly pull back.
+Gren Moyo couldn't you use some fiberglass fabric and reason its got the flexibility right?
+Rambo Isreal maybe. its just the reasons behind why historically recurves where used. welsh longbows, aka the english longbow suck to shoot with there 100+ pound pull weight
no it is because some people didn't discover that technology yet
This bow is amazing! I recently went to Lowe's and picked up the materials which added up to about $6.50-7.00 and this bow is surprising! In 20 minutes I made it, and the hardest part of the build was getting the string the right size. Now I can hit a rabbit size target consistently from about 70 feet through many large tree branches here in Alaska!

Comin back 6 years later lol, havent watch ZNA vids in a while always a good time watching u bro
Oh love that re-curve bow. In my opinion, yes it does increase arrow penetration due to the back torque offered from the re-curves that go through higher string tension mechanically by design rather than more weighted manual pull back in a single curve bow.

I once made a 60+lb recurve bow out of 3/4"pvc without fiberglass, it was cool. The thing put our 50lb compound bow to shame, which was amazing. I could manage about 5 shots before my arms got too tired. A past of the success was because I made a string for it rather than use paracord. The string doesn't stretch, so you get better energy transfer and less wobble upon release. Highly recomend both heat-moulding, and making a proper string.
How i made? pls
Heat moulding?

I've read a lot of comments that try to explain why the recurve is shooting more efficiently, yet none thus far has mentioned the most important aspect: mass.
When you loose an arrow, you're not only accelerating the arrow, you're also accelerating the bow itself. Heavier limbs and tips mean less energy is going towards the arrow, thus a slower shooting bow.
the "subscriber" bow is made out of 3/4 inch PVC and it DOES NOT contain fiberglass rods, it's simply heated and tapered, which means it's thicker at the handle and gets flatter towards the tips. This results in less overall mass. The recurve design essentially has the effect of having a longer limbed bow, making it more efficient. It also reduces an effect called "stack" (meaning that the draw will feel more even rather than get harder to pull towards the end as the angle between the tip and the string reach 90 degrees, as is the case in longbows).
The reason why the "monster bow" didn't perform as well is mainly because you weren't pulling it all the way back, longbows have a tendency to stack towards the end of the draw, meaning that you're losing a lot of energy by not drawing it all the way, even if it's 2 inches or so less than full-draw. Another reason is that it has significantly more mass including that of the larger 1-inch pipe and the fiberglass rods.
One might think, "wait, aren't the fiberglass rods and larger diameter pipe supposed to have more power?" the answer is yes, they do, however, it's an issue of balancing that extra power with the extra mass.
Put simply, light and well designed bow of decent or even light draw weight is a better performer than bulky, more massive longbow of very heavy draw weight.
Good breakdown. I wonder if the comparative performance of the heaviest bow would be better if he repeated the tests using heavier and heavier arrows. Will the heavier arrow at some point fly faster being shot from the heavier bow or will the lighter faster bows still retain the ability to cast the arrow just as fast?
This is the longest UA-cam comment o have ever seen
@@catocall7323 I suppose that if the heavier arrow gets shot at the full draw distance ill make a difference by itself.
And there should be a trust to weight ratio that is exactly optimum for the bow. If it has more power, so, yes, the heavier bow would benefit more from heavier arrows, but again, at full draw distance.
@@LucasG745 And important educational comment.
what if that recurve had the fiberglass rods inside?
Hey i do appreciate videos like this because when i was younger, my brother and I would always be out in the shop making homemade weapons and such, but back then there was no UA-cam. The things i know now that i didn't know back then.
Wow, impressive addition with the fiberglass inserts. Good stuff man, thanks.
From what i know about the recurve bow is that it was originally made for horse back archers around the time of mongol and classical Rome because it allowed the user to have a smaller bow that was more mobile to use on horse back but had the same strength as a long bow.
Jaydon Ferguson M
Jaydon Ferguson
Jaydon Ferguson the recurve wqs made to lower the draw weight while keeping the power, the bow you are talking about is similar to a recurve but only half the size. my recurve is 68 inches and my horseback boe is 34 inches
Jaydon Ferguson huns* Mongols were 800 years from the fall of Rome, but did use recurve bows as well
Central asian tribes used recurwed wood made of deer horn, a special tree and most importantly they used hide to make the bow recurved. Aim of making these type of bow is to make a comfortable and powerful bow for on horseback riding and on foot too( It is way more easier to carry than a long bow). I dont know how romans made that type of bow but it is possible that they saw it from some of central asian tribes. Because a lot of tribes migrate to west and do their stuff you know Attila is one of them.
*Recurve bow*
From Wikipedia, the free encyclopedia
A recurve bow is a bow with limbs that curve away from the archer when unstrung. A recurve bow stores more energy and delivers energy more efficiently than an equivalent straight-limbed bow, giving a greater amount of energy and speed to the arrow. A recurve will permit a shorter bow than the simple straight limb bow for a given arrow energy and this form was often preferred by archers in environments where long weapons could be cumbersome, such as in brush and forest terrain, or while on horseback.
i'm honestly impressed by this guys archery skills

Hey Eli I'm the one who sent the bow. I was curious on the method you used to weigh them. Granted there are many factors that could affect the draw force.(namely my bad guessing) But if it has been shot fairly regularly it will break in, meaning it will get used to bending and flexing so it wont have as much resistance. my guess is that it was originaly 50-52 lbs and dropped to 45-48ish, just a theory. For the core i used three fiberglass rods one was 1/4in two were 3/16in. the 3/16 in was cut at 18in. ant the 1/4in was cut at 10in. then they were centered in the bow. Hope I helped if, not... oh well.

Thats the way of the ancient hunnish taltos Imagine?
The recurve adds arrow speed and power with a lower draw weight, but they never reached popularity when they were invented (medieval times) because of the amount of time and effort that went into making just one bow
Recurves are much older than medieval, there's records of them in antiquity, namely Scythians. But the theory still applies about the time and effort needed to make it.
Although, the Mongols and Turkic tribes loved them since they were so easy to use on horseback.
Thats simply not true. What it does is increase the drawweight in a more compact package. It does not magically become easier to draw.
*Anders9009*
This is the correct answer. For anyone with even a moderate understanding of physics and engineering, they would know that draw weight is directly proportional to the velocity of the arrow released. Assuming you're using the same exact kind of Arrow, and it's the same person shooting it, then it's quite literally impossible for Two bows with the same draw weight that have any difference in the launch speed of the arrow. Different designs May impart the force to the arrow differently, with some bows having a shorter but stiffer draw, and others having a longer but smoother one, but assume you released them all the way then the moment the our leaves the bow it will have identical amounts of energy. Draw weight is literally the only thing that affects this.
eGULZ you are smart.
+Obergruppenführer John Smith
- Don't know what religion you're preaching, but as far as actual physics and engineering is concerned there's a thing called "friction".
Draw weight aka potential energy does not convert 1:1 into arrow velocity aka kinetic energy - that's just stupid. More efficient bow designs such as the recurve will transfer more of the energy.
Ingenious !
It's almost like an inside-out Bundle Bow !
Just to let you know about the recurve bow. The one aspect of a recurve bow is that you have a more steady tension load throughout the entire draw. For instance, while the bow is sitting static you could have 35 pounds and at full draw you could have 45 pounds so roughly there would be a 40 pound exerted pressure on the arrow from when it is released, at your grip, until the arrow separates from the cord. More importantly, you are at 35 pounds of pressure against the arrow when it leaves the cord.
A long bow starts at 20 pounds and will pull back at full draw to about 80 pounds. Unfortunately, the average is not adding both and dividing by 2 because most of the draw weight at 80 pounds is in the last 2" of draw. So you start with 80 pounds of acceleration pressure against the arrow and then it decreases rapidly. Having this deceleration of acceleration causes the overall performance of the arrow to not penetrate as well. The best way to test is not into a target but to test the Feet/Second the arrow is traveling.
First side note, Drawing back a recurve at 45 pounds, a person will normally have a full draw. As opposed to a 3/4 or 7/8, shaky arm draw, due to the fact that it is easier to pull back a full draw on the 45 pound recurve than it is on the 80 pound longbow.
Second side note, it seemed that the recurve hit more centered on to the target not moving the target as much. This would be like catching a baseball stiff armed as opposed to using your elbow for recoil cushioning. The ball won't bruise your hand And, the arrow won't penetrate as far into the target.The longbow seem to move the target because it was hit off center. My suggestion to correct for this, put the target against a solid backstop.
I hope this helps.
Damn you are good
can you tell me alternates for driveway marker
the recurve bow is a non-mechanical way of emulating the compound bow. that is why you are getting the same velocity with less effort
The Recurved tips act like spring-loaded, elliptical pullys, that only get "loaded up" at the end of the draw. This allows a more constant draw on yur arm.
Kevin Navitas emulating the compound bow?
Seriously man? Think about which came first.
Recurved tips a) increase early draw weight by preloading the limbs more at brace, and b) reduce string angle at full draw which reduced limb stack and stores energy more efficiently near the end of the draw.
Also, I'm guessing the limbs on that 70-pounder are really heavy (mass wise), in which case much of the energy stored in the bow is spent accelerating the limbs instead of the arrow.
Jesse Rudolph okay let's talk about mechanics,
The compound bow emulates the action of a recurve bow that uses a mechanical function to have an easier drawn position.
@@tannerjones1737 No no no.. The compound bow is specifically designed to shift the maximum draw weight away from the end of the draw, so you could hold a maximum draw easier, not struggling to aim. The recurve doesn‘t do that. It simply snaps faster than any typical design, so the power transfer from the limb to the arrow is better.
how to make arrows
xave man look up a video. 3/8th inch wooden dowels should be fine. Goose feathers work as fletchings. You can make an arrowhead from any metal. A broadhead from a spoon or saw blade or w.e or a regular target point from rebar. Or you can flintknap yourself one. Should be like 28 or 30 inches or so. Depends on your draw length I believe.
This isnt Google.
how to english
Find straight stick, make stick pointy, give other end of stick notch.
Recurve bows store more energy making your draws more efficient this doesn't necessarily make it more powerful but your drawers are more consistent if I remember right you also get like a faster a shot
Basically adds more energy and speed for less effort

Damn my favorite pvc bow channel is a knife making channel
Just made this bow today... Still gotta tweak it some but i love it and its awesome!!! Youre amazing and keep up the awesome work
I really want to see how to make the re-curve bow.
My first PVC bow-making efforts involved stuffing the PVC full of fiberglass rods; it increased the draw weight tremendously, but decreased the power of the bow. Eventually I realized that increased draw weight doesn't help unless it increases acceleration of the arrow, so let's look at what interferes with acceleration. The bow I built had two major defects: all the fiberglass rods led to internal friction and movement -- wasted energy -- and the sheer mass of the fiberglass towards the ends of the bow worked against acceleration. (acceleration = force / mass, so higher mass means lower acceleration; and the worst place to put that mass is the part of the bow that has to move the fastest.) On top of that, the maximum acceleration of the bow is limited by whichever material returns to its original shape more slowly, PVC or fiberglass; it becomes a worst of both worlds situation. So it makes sense to me that your bow with the heaviest draw weight is not providing the penetration you were expecting: sure you're putting a lot more energy into drawing the bow, but the bow isn't giving that energy back efficiently.
This actually makes sense. So when building such bows the trick will be to find the balance eh
@@finethehuman1821 A bit of a balance, but probably more than anything, being selective about materials. First consideration is a material that deforms under force but then QUICKLY returns to its original shape. Then pick the ones that offer the most force while being the lightest. Found this interesting article about bow wood:
www.wood-database.com/wood-articles/bow-woods/
@@kingbeauregard that was an interesting read, albeit about wood. Unfortunately I donot have access to any kind of wood so I'll have to stick to PVC. Trial and error time haha
@Nate River Right. I am hardly a bowyer so my experience is anything but definitive, but fiberglass seems to make things worse. The right combination of materials can make for a great bow, but on the other hand, look at what Lars Andersen can do with a stick and a string:
ua-cam.com/video/Bbd90L3NU2Y/v-deo.html
Note that Lars says you should try to learn archery on a good bow; that makes sense, you can probably learn the fundamentals better on a bow that isn't fighting you. Still, look how fast those arrows are flying!
@Johnny Wass I won't claim to be a physicist, but I have built a few PVC bows in my day. First one I built was a monstrosity made of bad choices: a pipe filled with fiberglass and big heavy caps at each end. The performance was absolutely terrible. I discovered I got much better response from just a straight PVC pipe that the string attached to on each end, even though it was much easier to draw. That meant the first bow was wildly inefficient, and trying to figure out what went wrong the first time, I realized that the entire bow needs to be built around accelerating the arrow. That means the limbs need to move fast, which means fixing anything that slows the limbs. Poor choice of materials will slow limbs, internal friction and resistance will slow limbs, mass will slow limbs.
I remember seeing this video years ago.
Some more of your vids popped up in my news feed. Love em. You got yourself a new subscriber
Making a pvc bow. Browsing UA-cam for ideas. See this. Nice 💯
Pro-tip: put a piece of tape around the area you are cutting on the fiberglass to help prevent splinters. You can still breathe them while cutting
I just made it and it works really well
Here i am it’s been five year since I first watched this vid and couldn’t make the bow because i was literally a kid but now.Now I’m going to make it❤️
Oh heck, it's so nice to see baby Eli LOL much love dude, also deep-diving some old videos because it's always nice to see these old instructional ones
I made a recurve crossbow using a old wood rifle stock and pvc limbs it has 90lb draw weight
Bobby Humphrey is that good?
Bernardo BR its amazing, if you can pull it that is
Mahamad Kader Op
+Bernardo BR not really. Most crossbows are consistently heavier than that. The way a bow works is it adds momentum to an object as the bow is releasing and there is a formula to calculate the force but it's basically the formula for work, MassxDistance=Work so the longer the draw distance the more time there is for the bow to impart momentum so that allows a longer bow to accommodate a lower draw weight while still being effective. Crossbows have a smaller bow and therefore require a heavier draw weight to reach the same amount of energy output so unless he has a longbow mounted on a rifle stock, it isn't that impressive. I recommend looking at Lindybeige and Skallagrims videos on the topics. Just search their username and bow or crossbow
MRCOLOURfilld If you are using a regular bow, 90 pounds is insane. Bows and cross bows function differently at their core. A cross bow typically has a crank, and you don't have to hold it back or pull with only part of your back, they will store the energy until you pull the trigger. With a regular bow, you have to manually pull it back and then hold it.
the strong bow pushed the back end of the arrow more and making the arrow unstable during flight..
45pound worked well on that arrow, the 75pound bow would surely work better with a different arrow.. i don't know how to explain it, but it has something to do with "Momentum" of the arrow leaving the bow
cyvidal10 You're close. It's the dynamic spine, or the stiffness, of the arrow. You need to match the dynamic spine of the arrow to accommodate the draw weight of your bow for accuracy and power transfer efficiency.
luigisf thank you so much :)
cyvidal10 ok
The shape of the recurve is what makes the arrows quicker off the string - if you draw a line from the tip of the limbs at full draw to the tip of the limbs at zero draw, the path drawn by the tips of the recurve bow is flatter than that of the path drawn by the longbow, resulting in a quicker acceleration of the arrow, and thereby a quicker and more efficient delivery of the projectile.
...not just the construction,i once saw in a video that those curves at the both end where the strings are knotted to gives an extra snap when the string is let go which increases the acceleration(???idk lol) I guess
You are a legend. Keep up the amazing work, man!
I'm impressed. I certainly did not think that would work. 👍✌
the purpose of the curve to the recurve bow was to increase penetrating power while having a lower draw weight. when the now is drawn, the curves almost completely straighten out, allowing the string to launch the arrow with increased velocity at a target. recurve bows were used in mainly the middle and far East.
Hahaha, I love the bloopers! This just got into my recomended section and i'm honestly gonna try to make myself this bow. Excellent!
Zivee Kyriolf shut up
That's honestly impressive man good job on the video.
Great video! I'm going to make one tonight! Super simple design and like you said pretty powerful. Thanks. Another fun fall project!
First video I’ve seen on your channel… Pretty impressed with it so I subscribed.
the recurve works by shortening the string (the part that is free and not touching the limbs) so that the angle at the nock of the arrow stays more acute (less flat, like when you are at the end of the drawing) and the energy transfer is more efficient. It's like shortening the limbs, at the same draw weight, while the arrow gets released.
I love bow and arrow🏹 so much please do more videos like this one
It's fun too see what you looked like 7 years ago!
The Mongols used a recurved bow, and they used it with great skill on horseback. Once united under Genghis Khan, the Mongols became one of the most deadly war machines ever.
No, there was no Mongol horde, that is a lie to hide the truth. The Mongols only numbered a few thousand and were nomadic living in a small, northern area in Siberia- NOT the Mongolia of the day. The horde was actually the multicultural forces of Grand Tartary and Ghengis Khan was blonde-haired, blue-eyed and of Slavic descent. There are portraits of this before the "Mongolian Rendition" of him. Grand Tartary was wiped from the maps and history after 1812-ish, but before that you can find references and maps of their vast country, which included N. America. Some speculate that the Great Wall was built by them to keep back the people that later became China.
@@GT_Void there was a Mongol-Turkic people living all over the middle asia to Syberia to Crimea, they were a horde truly
@@GT_Void This is some completely unhistorical nonsense, where did you learn this? It isn't at all supported by any serious or respected historians that i have ever heard of.
@@GT_Void It is obvious you have no idea what you are talking about. I have family who are Mongolian and you contention that Temüjin was Slavic is so stupid it is hilarious, particularly because his geneology is extremely well documented.
@@SRLowther Not really. Entire cultures get brainwashed with lies to change history. Happens all the time, especially in totalitarian areas. The maps don't lie about Grand Tartary. Look it up.
does this guy work out or did the muscles just come from shooting bows?
Dmitry Galkin shooting wouldn't leave you that muscley in archery you really only use your back muscle
Hazed bullll when I was younger I went out every day with my bow and after about 3 weeks I was noticably stronger
Not saying this is the same for everyone just sharing my experience
Well the back is a pulling muscle so when he's pulling the arrow back he's contracting part of it plus he has low body fat so
Push ups brother every day lots of sets will get you stacked.
Incredible advise Sir Pig. xD
very crisp and nice video. recurve is indispensable because it is a multiplier of power .
Excellent vid bro, exactly what I was looking for.. thanks 👌👍🎯💪
5:43 yes the recurve adds to velocity of the arrow however , your video is very good and very useful , I hope you continue doing what you do and continue perfecting your style of bows. Thumbs up
Why am I here and why was this recommended to me? Still interesting tho
you answered your own question
Shane Recktenwald That escalated quickly
Shane Recktenwald you are so cute sweetie pie
I can't stop watching this
Fantastic editing & paced thank you for a great video!
short answer, the design of the recurve allows for more initial pull weight than the long bow, storing more energy per inch of draw.
deth502 why?
physics.
i guessed, but i was hoping for an explanation :)
The reason is quite simple and you have to look at the bows when they are unstrung to fully understand it. The one in the video is a straight bow meaning that unstrung it is a simple line. Now the recurve bow unstrung has it's limbs well ahead of the riser (middle point). Therefore when the recurve bow is strung it stores far more initial kinetic energy as it has a much higher initial tension and the string upon release has a much longer travel as it tends to be much closer to the riser = more time accelerating the arrow. Compare it to a short barrel rifle with a long one it's the same thing. Hence the difference between the 45lbs recurve and the 70lbs straight bow shown in the video. All in all looking only at the weight of the bow is misleading. You have to know the speed and the weight of the arrow upon shooting it to determine how suitable is a bow. Depending on your purpose for using a bow you might want to sacrifice speed for noise and accuracy
Christoforos Paphitis great explanation dude..
Normal people seeing the thumbnail : how to make a bow from pvc
Me seeing the thumbnail : man does back gains
this video was pretty cool I like it. Now I want to make bows just like that. i will write down the materials and the tools you showed in this video and follow your instructions to make my very own bow. I really hope to see more videos like this one. Keep up the good work pal
Indeed, very good bow.. Well done bro👍
Recurve bow ftw
for the win*
Used to do this all the time as a kid.
Just made one of these things. took me a while to figure out how to tie the bow knot and how to get the string to be the right length, but it was well worth the effort. thanks for the tutorial!
Do you know what diameter your driveway makers where? I have to buy mine online and trying to figure out the right size
Those driveway markers would make good arrows.
if they break tho or get scratched the fiberglass fibers will sting like hell
Not really dude, never do that. Those highway markers can flex well but split easily. So they're great for adding power to the bow but will shatter on impact as an arrow
you can buy kids practice arrows for like $2. they work pretty well if you aren't trying to kill anything.
Alexzander yo wait hold on, did you just say “shatter on impact”?
Now wouldnt that be effective as an arrow in real battle. I mean you wouldn’t want the enemy to hit you back with your own arrow right?
Also... Possible grenade arrows?
@@eomersimbajon2938 that shit impact everywhere and the shatter could possibly hit you back
