@@chroma6947 Joule tells how good it penetrate and momentum how far. That's why arrows penetrate soft targets better than bullets (soft doesn't need kinetic energy as much as momentum, and bullets are high in kinetic energy and low on momentum, arrows have the opposite) but fail to penetrate hard targets such as armor, that bullets are able to penetrate.
Dude, don't apologize about things that are not your fault.. like a neighbors chainsaw - people that get bothered by this, shall mature :D - love your videos and the content made together with Tods Workshop ;) very valuable!
Very cool. To me it seems as though the Yew selfbows were better performing. One thing that I have noticed is that the shorter draw bows tend to be faster than the longer draw bows. IE, the 28" draw length bows shoot faster than the 30"+ draw weight bows.
Hi Joe, really like your videos . i have a question, when drawing your warbow are you using your latisimus dorsi muscles in your back? i actually have a damaged clavicle and also really bad bad tennis elbow in both arms from years of scaffolding and weight training so i find it difficult to draw even bows of 47lb. and can only shoot about once a week. If you can give any pointers on the subject I'd be most greatful

@@Joegibbs-archery I could not find any, it would be a unique video. May be a video collab with Joerg Sprave work, because he has access to many companies and contraptions himself! May be he himself can make or mod one. Joerg also made collab videos with Tod too. In that video Joerg fire a probably 140lbs compound bow contraption which sounds like a rifle tbh.
Wonderful pair of videos Joe. What amount reflex if any do some of these laminates have in comparison to the self yews? I know you mentioned one had natural deflex. Or maybe to word my question better, how much do you think an inch or two of reflex adds to the performance of heavy long bows at the otherwise same draw weight? Thanks again.
good follow on video. As you said not much in it. Do you think the lams are more durable? Saw you prefer the draw on selfs. waiting for the tree to drop in the garden across the fence 😊
Good afternoon all, u am just looking to get into archery and I was wondering if someone could point me to the resistance bands that Joe is using. Also is there any good groups clubs around the west yorkshire area.
Look up “H1llb1lly Bows” on Facebook, it’s Joe’s own archery company in the UK (substitute the letter “i” for the 1s, I didn’t want to type out the actual word in full in case UA-cam considers it a censor-worthy slur lol) If you reach them via phone or e-mail, they should be able to help you out
Hello Joe. How many arrows can you shoot consecutively? How long does it take for you to get off 1, 2 and 3 sheaves of arrows in one go? What draw weight do you have to drop down to in order to shoot all these arrows? There you have a good test you could do for the camera. A test like that will get your name into academic articles for sure. This is one of the big unanswered questions in regard to huge battles like Crecy, Verneuil and Agincourt. How many arrows could they shoot and within what time frame? You're probably the only person capable of doing such a test. And for the record, I'm not talking about speed shooting. Only 6 arrows or so per min in the beginning. According to the Eulogium Historiarum, some archers loosed over a 100 shafts at the battle of Poitiers in 1356 before the battle was decided. Geoffrey le Baker indicates that in order to do this they had to recover arrows from the ground and from the bodies of “half-dead wretches” during a pause in the fighting. That's another fun test. First 50 arrows or so, then a 10 min break, and another 50 arrows. Cheers
interesting! Strange how a 25% increase in draw weight gives only a 5% increase in speed. I expected the difference to be bigger. Do you have any idea why that might be?
These heavy warbows operate like trucks. They can cast a very heavy arrow with not much loss in speed compared to shooting a lighter arrow. The same principle applies when driving a truck that is carrying a load vs a car that has no load yet the truck can't go much faster even if you unload it. The ELB's can shoot very heavy arrows very efficiently but they don't gain much in terms of arrow speed from shooting lighter arrows. Or at least that's how it appears to me.
I'm not an expert. The 2 bows are made from different materials and I think that the speed with which the limb moves might be different. A bow with faster limbs but lower draw weight might be expected to release a faster arrow but might start to lose the speed advantage as the arrow gets heavier. Please feel free to correct me, I'm just guessing.
Yes, those tropical hardwoods are much denser than yew. Makes an especially big difference in upper limb mass, where the energy storage is least critical and inertia most relevant.
Can you pleae do a chronograph test of your 200lb bow, when you can do it. Also do you believe if there were 6ft5in warbow archers, could they get significantly more energy by drawing a 35 -36 in arrow at 200lb draw. My goal is to be able to shoot war bow weights.
@@benn30ify Actually, it's the opposite. Using too light of an arrow can damage a bow. There is no danger of using heavier arrows, provided they have an adequate spine. In fact, as the arrow gets heavier, efficiency of the bow only increases, and kinetic energy transferred to the arrow only increases.
According to English sources, Henry VIII (if i remember correctly) said that there was no man left in England who could shoot quarter pound arrows (113,5 grams), so according to that, we can presume that that is as high as English went with their arrow weights. When we look outside of Europe, the Manchurians used regularly 80 to 120+ gram arrows, also the japanese and indians had really heavy arrows, but i don't know exact weights. Some tribal hunters/warriors shoot up to 200 gram arrows that are over 50" long, and the heaviest i know of, is Korean iron arrow of around 230-240 grams, it was a special purpose arrow and required a special bow for it, quite similar to manchu bows, their normal war arrows were quite light, only around 32 grams. It would be very interesting to see those tested.
Ignore them. It's not like they are ever going to buy a bow from you. Any poofter questioning your integrity doesn't have the arse to draw a bow over 35 lbs... ;) Thanks for the information (loved your work with Todd and Toby on the arrow vs. armor vid. Great stuff!)
pretty impressive speeds for a heavy arrow. good demonstration. thank yew
bow 1. 130lb at 30": 1; 112J 2; 116J 3; 121J
bow 2. 160lb at 30": 1; 123J 2; 128J 3; 135J
Based on that, we should maybe test even heavier arrows to see at which point we stop noticing energy increases?
Should be momentum not joule

What fps you get roughly at 10 gpp
How many pounds to start the lawnmower??!! Mine is about 250 lb!

Good vid again. Do you consider there is any difference in the feel of shooting the self Yew vs the laminates?
Hi Del. Self yews are sweeter to draw then lams.
@@Joegibbs-archery Hi, yes that was my impression, but I wondered if you felt the same. :-)

Thicc bows :D
Have a custom 200lbs modern compound bow made and shoot it. It will probably tear apart the fabric of reality :p
Cool do you have any video??

Comparable to the natural Yew, but think I remember your Swiss Yew got a 214 fps, the winner.

Or maybe to word my question better, how much do you think an inch or two of reflex adds to the performance of heavy long bows at the otherwise same draw weight? Thanks again.

He sort of answered this question in one of Tod stuffs videos on armor penetration testing (worth a watch).

Do you have any idea why that might be?
maybe the higher mass of the limb which must accelerate too?

@Jason Tsang He's talking about the exact same projectile fired from a different bow.

Hi Joe! Great video, great shooting. Feel free to comment on how they shoot and stuff like that
are there any arrows in the 100-200 gram range? would be interesting to see their kinetic energy
Unfortunately you will damage the bow faster if you use such a heavy arrow, it will exhaust the bow limbs.
@@benn30ify Actually, it's the opposite. Using too light of an arrow can damage a bow. There is no danger of using heavier arrows, provided they have an adequate spine.

Machu bow arrows were really heavy
According to English sources, Henry VIII (if i remember correctly) said that there was no man left in England who could shoot quarter pound arrows (113,5 grams), so according to that, we can presume that that is as high as English went with their arrow weights.

@@benn30ify that's a myth 😆
More bows more data, wonderful.
I see your Video on the effectiveness of long bow against a breastplate...did anyone take into account the velocity of the on coming target 🤔
Hi, man! I saw this video of yours and got up from the couch to go shoot with my little #40...
What would the approximate cost of bows like this be at?
Thanks for the vid! What screaming chainsaw?? ;)
Just tell us the velocity. We trust you...
But some wont so sadly I have to
Ignore them. It's not like they are ever going to buy a bow from you. Any poofter questioning your integrity doesn't have the arse to draw a bow over 35 lbs... ;)

Interesting tab.
Can I buy this?🤔
Are you builidng that longbows all by your self?
Yes I make and sell them
What are your thoughts on shooting on the right side of the bow?
Are the speeds feet per second
Yes
You gotta do a collab with Joerg Sprave, he can make you with a 200lb Instant Legolas.
