I'm ordering a Samick Discovery 60 inch recurve bow with 17 " riser and 43 " limbs ( so a 60 lb bow altogether ) the limbs are the carbon outside w/ wood filled inside and it will be the 60 lb bow ... whats the best string you can make for me for it .. If you can look up the samick discovery maybe .. would it be a good idea to have a flemish twist since they don't have a serving at the ends ? Id like a good fast and quiet string if possible or whatever you recommend for that type of hunting bow ... Thanks ! James
Archery is a healthy exercise not only for muscles, but the mind, eyes, and soul, and it helps to put it all together in ballance. Thanks for your inspiring videos.
Yes it's amazing how an arrow wobbles in flight. Helical fletching will help stabilize it. One of the biggest reasons people like carbon arrows is that they recover quicker. This wobbling is the Dynamic Spine of an arrow. That is what we are trying to adjust when we "tune" a bow and arrow.
8:20 You never really talk about which arrows you are shooting or how you are matching them to the many bows you build and shoot, but a properly matched arrow will minimize the left/right miss issue you describe here.
Kramer, just received my t-shirt and tumbler, thank you very much. Looking forward to more videos and getting more gear in the future. Thank you again.
My guess is that your arrows aren't "reversing" their direction of rotation in flight..the rotation rate is simply changing (accelerating or decelerating roll rate) to the point that your frame rate records it and your eye perceives it as such.. Ever watch a cars wheel going down the highway next to you, and see it suddenly appear to begin rotating backwards? Or see how a helicopter blade will appear to rotate backward or even stand still, depending on frame rate? Same thing.
@@dewboy910 disagree. shoot them into a target 1 yard in front of you. the string wants to spin arrows counter clockwise and everyone fletches for clockwise. you're working against the rotation. Levi Morgan explains it well in his video. people should probably all be doing left or counter clockwise on their feathers. imo. it was eye opening to me to watch high speed cameras
Got my string in the mail today. Strung up my Black Hunter and did some test shots with it. Very Smooth and feels better than the default string that my bow came with.
Cant decide if I should I get the black hunter longbow or recurve?? Looking for some cheap practice until I finally build my own masterpiece...Being that I cant even decide on a what design for my next bow it might be a while.
Dude that's crazy! I totally understand why you make your arrows big, heavy end forward!!! When it bounces off the shelf the smaller end on the nock is less likely to rub the rest on the way out! Then the helical fletching that causes spin tightens the circle that the flex causes! See for the first year I couldn't get an arrow to fly straight at all. It was when I compounded a foreshaft, it relived stress. Allowing more paradox. They flew much better! My first arrows we're far too stiff. But I still don't spine check my arrows. It is some just behave much better. Dude crammer, I really appreciate it! I really just figured something out!
2:02 that bow has a window cut through the center , hence the riser is not in the way of the arrow flight. Flex of the arrow can be explained in physics concerning motion from static and those energy transfer hoohah, lol, right?
With your 1000 frames/second, it would be really interesting to see how your bow reacts during a shot. There was a shot or two showing how the bow moves after release, so please show us more!
Good day for a good day! Awesome that you captured the change in rotation of the arrow with straight fletching. In general, bowstrings made with counterclockwise twists (looking down string from either end) will cause a bare shaft arrow to spin counterclockwise (aka right spin). Using right wing feathers with a right helical fletching on a string with counterclockwise twist will produce a consistent right spin from the start. Of course, your finger release can affect this. Great stuff - keep it coming!
Risers with arrow shelves/plates cut way past center (i.e. the Mandarin Duck Black Hunter) can accept a wide range of arrow spines and only mass weight will matter. As the center shot window is decreased, arrow spine selection criticality is increased. Arrow paradox flight always looks remarkable if not confusing in hyper slo-mo, but really matters little. What will matter most will always be a bow's relative shelf/plate center shot, and shaft selection for spine and mass weight. Lots more arrow spine concern with a thick handled ELB than a Black Hunter R/D bow. Then there's the matter of the inconsistencies of wood shafts as compared to those of carbon fiber. And shooting technique, too!
@@rfdsrd mr hill is dead and you see the arrow in the movie flexing and hitting the riser with a center shot bow and that proves newton and euler, where did you learn about archery anyways... UA-cam?
Howard is dead? No foolin'!? You miss the point, pun not intended. A *LOT* has to do with the distance of the arrow plate to the centerline of the string. The closer to centerline, the less gross effects of the paradox and thus the less concern over arrow spine. If you don't understand or believe this fact, you haven't been in the game for the last 70+ years.
@@rfdsrd this bow has a shelf so to surfaces to react on the force of the arrow, yes the string travel towards the riser at an traverde angel and this bend the arrow against the riser, that then again pushes the arrow out newton 3rd law, regardles of shelf plate, it even happens with fallaway rest on compound, also H. H used a dead release
That is really interesting to watch. It's like, when the arrow leaves the bow there is no way it should hit the target. But it seems like the arrow has a kind of memory and it's constantly flexing to bring itself back on the line it was originally shot from. Cool video man.
It does not constantly flex, that takes energi as gravety slow the energy it will start to spin and stabilise so the point dont move left or right. You aim of to begin with caus the spine is dynamic and changes trough out
Your arrows will spin in the opposite direction that your string is twisted. Twist your string in the opposite direction and let's see if your straight-fletched arrows also change direction. Some say that the change in the direction of the arrow in flight affects the accuracy (i.e. left helical with a left twisted string). I think we need another video.
Have you tried testing the arrow spin without fletching? From what I remember, a bareshaft shot from the left side of the bow will turn counterclockwise (usually) and you want to apply your fletching in accordance with the natural spin of the arrow for your particular bow/arrow setup.
All carbon arrows have a natural ration. Also the direction your strings are twisted will have, clock wise or counter clockwise an affect. So with a straight fletched arrow there's no forced rotation put into the shafts.
I would love to see you do a horse bow build or a static recurve or a scythian bow. You seem like just the guy for such an interesting project. Anyway, thanks for the awesome videos!
first I'd like to say a couple things that is just totally awesome I really like how your videos have an explanation Plus entertainment so also you're adding skills are out of this world and I finish making a bow following one of your tutorials and guides and I'm really happy with how it turned out
I'm sitting here really confused now. Thanks Kramer. 2 things have me puzzled. Why did the arrow change rotation and why did it take 40 yards to stop flopping about like a fish out of water?
Many traditional bows are not centershot bows, especially longbows of many types. Centershot recurves are out there but when you figure in elevated rests and arrow shelf side plates, it takes the centershot out of the equation. Not by much but a wood riser recurve is just barely cut to center anyway. Doesn't take much to throw it out. You still have a riser that doesn't allow unimpeded travel to the target. Ever notice how most trad bows are shot canted? Thats why, the riser somewhat blocks the target. Yes, your modern ILF bows are made and can be set up to be totally centershot but they are a different breed of bow
The reason that your fletches are reversing, is due to the twist of your string. I mark a bare shaft and shoot up close to a butt to see which direction the arrow is spinning, then I fletch them with the same angle so that they will spin the same direction the string wants to spin them. Otherwise your arrows are flying kind of like a pitcher throws a knuckleball, which is not good. Most people don't realize that your string will cause the arrow to spin depending on which way it is twisted, right to left or left to right.
The human eye normally sees the images as if they were from real life if you exceed 200 FPS. In more regular terms, the point where people notice changes in the smoothness of the moving images is around 90 Hz.
so with a modern bow with a cutaway shelf, or a drop away rest, or a crossbow, wouldnt it make sense to shoot the stiffest spined arrows you could find? and that would be less wasted energy in flexing and in turn transfer all of the energy more efficiently into the target?
Hi. I watched a test that showed the way the arrow twist with straight fletching is determined by the witch direction you serving is on the string. Perhaps an idea for a new video??
With the arrows appearing to change rotation mid-flight, it's probably an optical illusion. The particular optical illusion is a common phenomenon that occurs with filming. Because film is not a continuous image put a series of frames, as a rotating object slows down there will eventually be a state where the rotational speed of the arrow is actually slightly behind the frame rate of the camera. So what happens is the arrow appears to be rotating in a different direction than it was before but really it's just not quite fast enough to complete the rotation so it just looks like it's going backwards.
Gives a lot more appreciation for Byron Ferguson shooting aspirin out of the air and why he is so meticulous in his preparation for the shots he makes.
The arrow bouncing off the shelf explains why you shouldn't cut yourself on the fletchings when shooting off hand on a traditional bow if you knock the arrow slightly higher on the string than perpendicular. I always wondered why that worked.
Question...if you glue your feathers on in a slight screw shape instead of straight, sort of corkscrew curve-shaped, would that make the arrow spin rate increase and like a bullet does when it spins, it would increase accuracy..? Always pondered why all the feathers at the end of an arrow are straight.
Loved this video on paradox. Would love to see same idea with different arrow spine to see how spine and paradox can effect shots. Also see how FOC effect paradox. As a hunter I want my arrow to hit an animal going straight and not flexing. Thanks for an interesting and educational lesson on archery.
I have a old bow and I need a string the old one has those plastic finger beads so you don't need a tab. Will those fit on a string I buy from your website?

Saludos de mazatlan sinaloa - Jorge perez
I’ve read that the twist of the string induces rotation in the arrow. Clockwise string twist throws a counterclockwise rotation in the arrow. Can you test this?
Ya I guess the paradox of the arrow curving or bending can probably be solved by a more powerful arrow or a heavier weighted arrow? Ya I got this piece of wood for a handle that I thought would be cool for a bow, but your shatterproof has the tools. Do they do custom bows?
After watching your videos. I have decided to try my hand at archery. Oh boy! It's fun! I'm in pain after 300+ rounds by first day. 😫 However I'm looking forward to shooting again.
Do u think that this effect would prevented by the use of an artificial arrow rest instead of shooting directly off the shelf? I know u can't use plastic arrow veins directly off the shelf but would it have the same effect fo u think on a rest?
When you release the bowstring, the nock end of the arrow travels first and the point end travels last. That's because the arrow shaft is flexible. If the shaft flexes towards the bow, it pushes itself away from the shelf and then flexes the other way. If the shaft flexes away from the bow, it looks like it's lifted from the shelf and then it flexes the other way. Has anybody compared if 1) you point the arrow tip at the target with 2) pointing the string and bow edge at the target (arrow tip pointing to the side)?
"When you release the bowstring, the nock end of the arrow travels first and the point end travels last" That is one of the best observations I have heard. I'm going to use that in future conversations!
I don't know for sure, but it seems like the arrow flexes like in a wave length in a lake when a rock hit the water surface, but the spine (the elasticit modulus of the shaft and its inertial modulus) is like the viscosity of the liquid and it follows the same natural behavior and the harder or wide is the arrow, less it bends and wave.
The shaft and spine of the arrow is not fluid, the straightness is acctualy messured by 0.100 decimal . The flexing is due to stress across the lenght vectoring at the nodes applied by the force relative to inhertia
the reason it is switching direcrion on the spin is because an arrow will naturally want to spin one way or the other and will vary bow to bow for number of factors. your arrows should be fletched accordingly to aid this natural spin otherwise you cause it to fight against itself and loose efficiency.
Hi my name is Quinn I just recently got in archery so, I don’t know much about it and I wanted to ask you a question. Um well, I just recently bought a beginner bow for my birthday and I’m having a lot of hand shock how can I fix that
can you reduce the bend in the arrow by shooting through a tube, several notches, or something like rifling, doing that would probably slow the arrow though...maybe getting the arrow to spin sooner
I wonder if there is a material out there that can be used to make stiffer arrows so you don’t have a archers paradoxes or the arrows don’t bend & flex , the Energy transfer from the string to the arrow is what creates archers paradox. I don’t know if you really need the arrow to bend & flex but I wonder if someone has tested a arrow that doesn’t create a archers paradox. I wonder if crossbows do the same thing being there’s no riser for it to go around .?
you can put a stiff arrow that won't bend, but then the arrow will be deflected totally away from the bow/riser (for traditional style bows) and will be nowhere near where you were aiming at full draw. in other words, you NEED the arrow to be flexible and archers use spines with the appropriate flex/stiffness for the strength of the bow
@@vodoopupped9687 of course it will flex on a crossbow. the force is tremendous. as i said put a 100 spine on a 5 lb bow and show me the flex. the arrow will deflect off of the riser and shoot off to the side
@@vodoopupped9687 every object with mass has inertia (i took physics in college too) but basically you are saying what I claimed. if an arrow is too stiff and the draw weight is too low, there will be no archer's paradox because the arrow flex is negligible.
@@vodoopupped9687 yes, the nock will move before the tip moves. if you want to be technical, the difference will be the speed of sound. i am only answering the original poster's question: "I wonder if someone has tested a arrow that doesn’t create a archers paradox"
Heyo, just a quick correction: The human eye does not perceive things at 24 frames per second. 24 frames per second is the agreed upon minimum to trick the human brain into thinking that independent pictures are in motion. Eyes don't don't actually see things in frames at all really, as all of the light receptors are constantly sending information to the brain, taking between 1/300th and 1/1000th of a second for the "signal" to travel from your eye to your brain. Think of this less like individual frames, and more like a steady constant stream of information on a slight delay. Anyways, very cool video!
Hi! Great channel! I've got question. Have you ever made a laminated bow from a lot of thin layers? Something like veneer maybe without or with pure carbon/glass fiber (roving)? Will it bow? ;) Best wishes from Poland!
Guessing the long range lob on traditional is fun, but most likely, live animal won't be standing there when the arrow arrives. Amazing how video quality degrades when filming on cloudy days. Wonder if higher end cameras help correct some of this? Crazy how a stiff arrow looks like a wet wobbly noodle heading down range. Do crossbows have a paradox? or arrow flex like this? Would be interesting to see. Frame rate is everything with slo mo. 60 fps is a minimum, 120 even better. 240 is magical on many applications. Thanks for sharing.
Clouds are natural difusers! Nd filter works and you can adjust your White and contrast balance, there is no paradox, just physics like Newtons laws that also apply to cross bows, the bolt pushes of the rail just like the arrow of the shelf,.
hello im new to archery and i was wondering when stringing the black hunter bow you recommended how many twists do i put in the bow string? it amazed me to find out that there isnt any information on this on youtube already
Caus it depends on what brace height you need for your arrows to clear the riser, ulike in this video where you can see it hit deflect and fly off sideways. And since the power stroke is relative to the arrow weight and spine and your draw lenght, tab, string material and strands there is no set answear but start at 7 inches brace height but dont go far above 8.
It's not apparent from the video that the arrow reversed in the direction of spin. Could it be an optical illusion that you saw the arrow reverse in the direction of spin?

It's great to see you exploring the mechanics of archery.
the flex isn't the paradox, it's the solution. the paradox is the arrow going straight even though it's slanted on a non-shelved bow.

After watching your videos. I have decided to try my hand at archery. Oh boy! It's fun! I'm in pain after 300+ rounds by first day. 😫 However I'm looking forward to shooting again.
P.S. THANK YOU FOR THE POSITIVITY!
That is so awesome!!!! Your welcome!
What's the specs of the $50 bow?
Do u think that this effect would prevented by the use of an artificial arrow rest instead of shooting directly off the shelf? I know u can't use plastic arrow veins directly off the shelf but would it have the same effect fo u think on a rest?
May i ask what that something like feathers at your bow string bow?
notice your shooting that cheap duck bow...niiiice!
When you release the bowstring, the nock end of the arrow travels first and the point end travels last. That's because the arrow shaft is flexible. If the shaft flexes towards the bow, it pushes itself away from the shelf and then flexes the other way. If the shaft flexes away from the bow, it looks like it's lifted from the shelf and then it flexes the other way.
Has anybody compared if 1) you point the arrow tip at the target with 2) pointing the string and bow edge at the target (arrow tip pointing to the side)?
"When you release the bowstring, the nock end of the arrow travels first and the point end travels last"
That is one of the best observations I have heard. I'm going to use that in future conversations!
I was going to say the same thing, but George beat me to it. George is right.
I don't know for sure, but it seems like the arrow flexes like in a wave length in a lake when a rock hit the water surface, but the spine (the elasticit modulus of the shaft and its inertial modulus) is like the viscosity of the liquid and it follows the same natural behavior and the harder or wide is the arrow, less it bends and wave.
The shaft and spine of the arrow is not fluid, the straightness is acctualy messured by 0.100 decimal . The flexing is due to stress across the lenght vectoring at the nodes applied by the force relative to inhertia
the reason it is switching direcrion on the spin is because an arrow will naturally want to spin one way or the other and will vary bow to bow for number of factors. your arrows should be fletched accordingly to aid this natural spin otherwise you cause it to fight against itself and loose efficiency.
Does this bow come left handed?
Where did you get a 1000 FPS camera...Id like to film my arrows
Curious if the arrow would act the same off different rests
Your video came up in my feed today, and I loved it! Where did you shoot this? I would love to take my kids here to shoot.
A bow cut “past center” can run stiffer arrows. Those stiff arrows may not take 40 yards to straighten out
Nice range, I frequent it myself.
I love it
Look into "clocking" to better understand natural arrow spin
Hi my name is Quinn I just recently got in archery so, I don’t know much about it and I wanted to ask you a question. Um well, I just recently bought a beginner bow for my birthday and I’m having a lot of hand shock how can I fix that
Great video sir.
How many bows do you have
can you reduce the bend in the arrow by shooting through a tube, several notches, or something like rifling, doing that would probably slow the arrow though...maybe getting the arrow to spin sooner
no
I wonder if I am correct in thinking that archer’s paradox is worse for long bows. If so why did you use a recurve?
I wonder if there is a material out there that can be used to make stiffer arrows so you don’t have a archers paradoxes or the arrows don’t bend & flex , the Energy transfer from the string to the arrow is what creates archers paradox. I don’t know if you really need the arrow to bend & flex but I wonder if someone has tested a arrow that doesn’t create a archers paradox. I wonder if crossbows do the same thing being there’s no riser for it to go around .?
you can put a stiff arrow that won't bend, but then the arrow will be deflected totally away from the bow/riser (for traditional style bows) and will be nowhere near where you were aiming at full draw. in other words, you NEED the arrow to be flexible and archers use spines with the appropriate flex/stiffness for the strength of the bow
@@vodoopupped9687 put it on a 5 lb bow
@@vodoopupped9687 of course it will flex on a crossbow. the force is tremendous. as i said put a 100 spine on a 5 lb bow and show me the flex. the arrow will deflect off of the riser and shoot off to the side
@@vodoopupped9687 every object with mass has inertia (i took physics in college too) but basically you are saying what I claimed. if an arrow is too stiff and the draw weight is too low, there will be no archer's paradox because the arrow flex is negligible.
@@vodoopupped9687 yes, the nock will move before the tip moves. if you want to be technical, the difference will be the speed of sound. i am only answering the original poster's question: "I wonder if someone has tested a arrow that doesn’t create a archers paradox"
Heyo, just a quick correction: The human eye does not perceive things at 24 frames per second. 24 frames per second is the agreed upon minimum to trick the human brain into thinking that independent pictures are in motion. Eyes don't don't actually see things in frames at all really, as all of the light receptors are constantly sending information to the brain, taking between 1/300th and 1/1000th of a second for the "signal" to travel from your eye to your brain. Think of this less like individual frames, and more like a steady constant stream of information on a slight delay. Anyways, very cool video!
Hi! Great channel! I've got question. Have you ever made a laminated bow from a lot of thin layers? Something like veneer maybe without or with pure carbon/glass fiber (roving)? Will it bow? ;) Best wishes from Poland!
4:04 is that a BlackHunter ?
Guessing the long range lob on traditional is fun, but most likely, live animal won't be standing there when the arrow arrives. Amazing how video quality degrades when filming on cloudy days. Wonder if higher end cameras help correct some of this? Crazy how a stiff arrow looks like a wet wobbly noodle heading down range. Do crossbows have a paradox? or arrow flex like this? Would be interesting to see. Frame rate is everything with slo mo. 60 fps is a minimum, 120 even better. 240 is magical on many applications. Thanks for sharing.
Clouds are natural difusers! Nd filter works and you can adjust your White and contrast balance, there is no paradox, just physics like Newtons laws that also apply to cross bows, the bolt pushes of the rail just like the arrow of the shelf,.
I have always shot a heavier spined arrow than what was called for, I shoot a 50 lbs bow with a arrows pined for 60.
Just an idea: Do the same tests using a whisker biscuit. I wonder what the difference will be.
Depends on the firmnes of the whiskers, will the arrow displace them or will newton 1st or 3rd law be dominant?
hello im new to archery and i was wondering when stringing the black hunter bow you recommended how many twists do i put in the bow string? it amazed me to find out that there isnt any information on this on youtube already
Caus it depends on what brace height you need for your arrows to clear the riser, ulike in this video where you can see it hit deflect and fly off sideways. And since the power stroke is relative to the arrow weight and spine and your draw lenght, tab, string material and strands there is no set answear but start at 7 inches brace height but dont go far above 8.
The arrows look like their groovin to the music
It's not apparent from the video that the arrow reversed in the direction of spin. Could it be an optical illusion that you saw the arrow reverse in the direction of spin?
Kramer, what range is this??
Heyyyy
Is PVC pipe bows good for hunting?
No
5:08 Magnus effect?...
I recognize your strings but did you build both bows as well? Cheers
What part of Colorado do you live in?
You would be much more handsome with the arrow case on your back!!! :-)
I don't know if it is practical, though.
