HOMEMADE COMPOUND BOW !

I used skis to make this compound bow!

• BUILD OF MY CROSSBOW S...

[@fosterechalimbana2160]

Had the bow set up at a pro shop. It performed just fine kzbin.infoUgkxQEKUoxLWwayEDZR0NKB-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.

[@rafaellastracom6411]

Great job! Fantastic to see a young man using his hands. Keep up the good work brother!

[@JeanDeBaillEngineering]

Thank you :-)

[@stefanm.3353]

+Wood'n Tech good job bro

[@afrodzack8065]

+Wood'n Tech good vid! but I feel like there was to much slack, and that making it longer would make it more powerful.

[@TheVessapaperimuumio]

I find it amusing how many people are commenting about the bow being "left handed" or "shooting from the wrong side". I imagine wood'n tech is aware of the common orientation and practice of shooting bows. However, the commenters seem unaware of the fact that archery also works the other way around; it is not unheard of and was not invented yesterday. It makes a lot of sense, is very fast and sometimes quite practical. There are several youtube videos on the subject, have a look.

[@canusakommando9692]

I always like to see how different people young and old solve problems. An old dog like me can always learn. The best questions I ever get asked come from white belts, not old experienced Black Belts. Good job kid. Kudos.

[@mgalyean]

The "pulleys" are supposed to be *cams*. That is the axle is supposed to be off center so that the radius from the axle to the outside of the cam where the string tangents toward the string hand varies as the cam rotates. This allows the pull to start out difficult, then ease up as the leverage (the radius is a *lever*) changes as the string is pulled further back. Think about the different sized gears on a bicycle, the idea is similar. When you fire with proper cams, the string speeds up toward the end of its stroke which better matches the acceleration of the arrow. This effect is directly related to why the string is hard to pull back at first, then gets easier.

[@mrkiky]

+Marty G Well that's just a more advanced concept. The pulley model's only benefit is that you can have a longer draw while the limbs don't bend as much, but it doesn't provide letoff. It's still classified as a compound bow though.

[@mgalyean]

+mrkiky, mmkay. Well, I learned from you that non-camming, round-pulley, compound bows are actually sold, but upon further research I found that these are a very small set and are typically for youth bows used by many different kids with different draw lengths. They are not an early concept from which advanced eccentic/cammed bows evolved, they are a devolution to address a market at summer camps and such. According to the *original* patent, the *original* compound bows had eccentric pulleys, or cams. www.google.com/patents/US3486495

[@eugenemorrill7009]

Marty. The first compound bows made used pulleys or more properly 'wheels' . Fella by the name of Jennings built them They were the ugliest things but the worked well enough.I never shot one of the first models but I did own one of the later model I Jennings. A big, heavy, bulky bow but none-the-less a good shooter.

[@edwardmurdoch5070]

@@eugenemorrill7009 I think there were even ¨intermediate¨ links in the evolution of bows with one cam and one wheel.

[@jelbuilderfilms]

Great work!!!! Love to see someone making stuff with creativity!

[@andyvang3136]

nice 5 pound draw weight bow

[@Ethan-wg6xr]

A bit mean

[@fordman7479]

only a bit though lol

it looks like the worlds first compound bow and its awesome

Dude that is so cool but the music was great to and the background too

[@ScrapwoodCity]

Nice work!

[@JeanDeBaillEngineering]

thanks :-)

[@joelongstaff7601]

Sir thank you for sharing your skills with us.After watching your video I think I am going to try building one for myself. I'm going to laminate the limbs from maple and carbon fiber.Well that's it I just wanted you to know some folks appreciate your efforts.

[@Nekomajin]

great idea of drilling the wood to snap the piece off :)

[@Ethan-wg6xr]

Wow great bow mate keep up the good work

[@JeanDeBaillEngineering]

thanks :-)

[@emil5855]

Tip! Try making the pulleys, like cams! it will work as a gearing. Thats the idea of a compound bow :)

[@paulwheeler6122]

I admire your tenacity to keep working at a project. There may be faults in your design but at least you have the guts to show the world your work. Ignore the bad comments. They are just twats.

[@mgalyean]

+Paul “Busy Fool” Wheeler. I agree that encouragement is a good thing if that is what you are doing, but to categorize "critical feedback" as "bad comments" that should be ignored is not going to help him make a better bow. Which I assume is a goal the maker is pursuing. Until the internet gets over the idea that anything but gushing praise without any critique is "bad" we are doomed as a society.

[@foxthebirdkiller5482]

+Marty G He never "categorized critical feedback as bad comments, so there is no need for your obnoxious comment. He told the dude to ignore the bad comments and he said himself that there are "faults in the design", so you'd have no reason to assume he was telling the dude to ignore critical feedback. Unless, of course, you wanted to make yourself look like a mature prominent member of society. Please take your head out of your ass.

[@mgalyean]

+FoxTheBirdKiller. Was I responding to you? Nope. Did I ask you to read so much into my response? Nope. Do we both have better things to do? Yep.

[@bearheadknives4484]

Looks awesome typically u being right handed would shoot off the left side but great work man

[@bollebeer44]

Sick bow

[@radicalleavemealone-ist7751]

the crackling in the music made me think my building was falling down

[@davegetliberalsout]

Good effort. Shows your brain and hand creativity. Keep it up..... ...a quick hint...when using the hack saw, drop the rig as close as possible to the vise holder. This will be a bit safer and give you less vibration. (Most important safety, as the blade will have less tendency to jump out and cut you.)

[@TheGamingStuffs]

@Grace Gamer Girl Handcuffs are hardened steel, Merle made the right call ;)

[@gunnargervin1275]

Unnecessary to saw off handcuffs: the chains break easy. On KZbin that is.

[@JeanDeBaillEngineering]

thanks !

[@nateb4543]

I'm trying to restring my toddlers bow and have no idea how cams work or how to do this. Shotting a compound bow for 7 years, this kid's understanding of the mechanics are tenfold better than mine.

[@toot43]

hey love the work

[@QuantikoOfficial]

That's cool. Pulley=Cam/Idler Wheel

[@colinanderson9295]

[@MikaleHicks]

Amazing

[@ecjfla44]

Good Job! Don't be discouraged by some of the "Pro's". When they post a response video, of their "made from scratch" compound bow. then they will have room to talk.

[@KraljCorvin]

seems like the bow lost some power ....

[@mohamedfaroukbalouli7809]

KraljCorvin he can't shoot a fly with it

[@TonyyStarrkk1994]

KraljCorvin It did. 1 pulley cuts the work load in half, and retains the draw weight of the bow, but you have to pull the string back double the distance in order to achieve its proper draw weight due to the pulley. Adding the second pulley cut the work load by 2/3rd's, but now he has to draw it back triple the distance in order to achieve the proper draw weight. That is wildly unrealistic, even at one pulley and double the draw distance because arrows simply are not made that long. He should have weakened the outer portions of the limbs, and adjusted the string tension accordingly in order to work properly with the draw weight he was going for. Compound bows are feats of precision engineering, not just slapped together roughly like this, and I doubt he took any of these variables into account lol. So yes, it did lose power, because at first he had to draw double the distance to achieve full draw weight, and after he had to draw triple, though it seemed easier, it only lowered the draw weight because of the finite length available to him due to the length of his arrows and arm span.

[@papasmjordeig]

weak but a cool thing to hang up your wall in your room and be proud of it. Good Job.

[@honeybadge4276]

PVC is cheaper and easier to work with so props to you. But what is the draw weight?

[@eugenemorrill7009]

A right handed shooter launches his arrows from the left side of the bow. If you try it that way, I think you'll agree that it is much easier and more comfortable. Altogether a good video. Keep trying. You will make a fine archer.

[@JeanDeBaillEngineering]

+eugene Morrill thanks, I didn't know much at the time as you can see

[@complexion235]

das frikin awsome!!!!!!!!

[@raoulvolfoni1800]

I'll buy you a set of wrenches for christmas .

[@mcfuckface7149]

the bow looked more accurate without the second pulley

[@draegore]

Nice job, except you made a left-handed bow (You are using a right-hand stance). On a right-handed bow, the cutout is on the left so its in-line with your aim.

[@chrispage3166]

most medieval shooters shot this way. look at lars anderson's video on medieval archery

cuz who needs washers....or wrenches....

You have the shelf for the Arrow on the wrong side

[@edwardbarr1533]

Clever boy!,,

[@codfan-ck5xq]

I made one

[@1955din]

Did not understand: what material is used to create a bow.

[@Anmatuur]

What sort of hellish noise is this?!

[@andersonhempton9671]

You can't pull it back because you don't have enough back tension. It is not about your arms, it is about you back.

[@baniohnamnongdhar3393]

what do you use as limbs

[@sherylpatente6370]

what if i don't have enough tools to make it ?

[@TheMustangForce]

arent your strings a little too loose?

[@richardjenkins5141]

what kind of wood did you use for the part to put your hand and what kind did you use for the limbs on the bow?

[@JeanDeBaillEngineering]

For the limbs I used skis but for the riser I have no idea.

[@Vladarius.]

but man i do say you a smart gut i think you 16 17 and you have maked already a compound bow i say man you AWESOME !!!!! and i sub you becuz i look up to someone like you ths for the pulley tutor

[@brianpowell9630]

Bruhhhhh learn some Grammar/English! This comment is so funny haha

[@Vladarius.]

thx but reallu i can see he is not older than 20 and its cool if somenona that age can do something like that then cool i dont have the right materials for one and im not american just you know ok

[@brianpowell9630]

Vladarius Wtf, I never said anything about his age??? Then what are you kid?

[@Vladarius.]

nope =p hmmm sry ok are you happy ?

[@richardjenkins672]

can you send me instructions on how to do this.

[@sergiuhalmajan604]

what material you had used for ? wood and ?

[@lukasfredriksson5834]

+Sergiu Halmajan Wood and skis

[@mehronisa1620]

it is very good I make it

[@000Trauma]

Do you even lift bro?

[@unshdhGbzbs]

1. the arrow rest has to be on the other side of the riser. 2. cut the arrow rest up the bow more so the arrow has enough space to bend. If you watch someone shoot wooden arrows in really slow motion, you will see that due to the speed its being shot it will bend up. if it cant bend up it wont stabilize and so it wont fly as straight.

[@JeanDeBaillEngineering]

thank for the advice . for now i am using wood dowels as arrows so they dont bend that much and for the arrow reste side i always thought it was on that side :-)

[@unshdhGbzbs]

yeah any wooden arrow will flex depending on the size you use. your size in this video will flex rather a lot so i suggest making it at least. 4 inches bigger. mainly so you can see the target better.

[@quantumvortex5637]

I still don't know how to make a compound bow

[@unshdhGbzbs]

no because this is not a speed shooting bow liike a horsebow its a target bow so you need it on the left to see the taget and the arrow flys closer to the mark you look at.

[@unshdhGbzbs]

i bet you watched the lars anderson video lately because your saying the right side is quicker

[@ericbrackin871]

Are the limbs flattened pvc or fiber glass

[@JeanDeBaillEngineering]

+Eric Brackin they are skis

[@dstyd]

Your bow is a little weak I would try using a better wood for the flexible parts. I am looking for a method to make a wooden compound bow without modern tools. I live in an apartment so I don't have access to a lot of space for making things let alone the electric tools. Raduka also made his out of skis but his was made with what I think was aluminum for the weal/cam and wood + plastic for the limbs. (had to look online to figure what the parts were called lol) He made his with drills, hacksaw, files and a grinder. apparently his was a 55lb draw. I am trying to identify the best wood for making one.

[@173618328]

which materials, I am interested the name of the flexible black wood that have

[@JeanDeBaillEngineering]

It's just random cross country skis. 3€ in a garage sale

[@173618328]

tanks

[@springbloom5940]

Good attempt, but not a 'compound bow'. A compound bow uses cams, not pulleys. The cams are offset in cycle, so that a heavy draw weight breaks over and is easy to hold and likewise accelerates the string as it cams back.

[@kazoolordhd6591]

is right handed... has shelf on light hand side

[@johndavid4360]

Yeah

[@RandomL0s3r]

Seen A Thumb Draw Or What Lars Anderson Does?

[@colinanderson9295]

SkyDogsGaming hi

[@stampedmetalsword8099]

I'm sure some surgical tubing has more power than that.

[@Vladarius.]

i dont understand the strings part all of its its just simple but idk how to put the string can you help me ?

[@JeanDeBaillEngineering]

+Vladarius The string should follow this pattern : top lim bottom pulley top pulley and bottom limb

[@gracekelly8964]

I can see now that in this video he can cut the rest of the screws off with a saw, but in TWD Merle can't cut off handcuffs with a saw. So instead he cuts off his hand. Wow. Lol

[@bossman9124]

well I suppose he could have cut the handcuffs, but then he wouldn't have that badass wrist blade!

[@fallingsuncreations9270]

You mean the bow was too powerful?

[@JeanDeBaillEngineering]

The limbs were to stiff.

[@zedjzara678]

what you going to hunt with that bow "marshmallows ??

[@RynaxAlien]

Plywood limbs?

[@JeanDeBaillEngineering]

Yes the skis are made of wood and fiberglass, but I am not sure it's plywood .

[@RynaxAlien]

Wood'n Tech Certain woods are also good materials for bows but fiber glass has greatest energy storage. Skis are made by combining wood and fiberglass probably also work good? I was watching video of guy who compared PVC to fiberglass bow and PVC is only slightly slower shooting.

[@g-mo7130]

Wouldn't this technically be a pulley bow and not a compound bow?

[@eugenemorrill7009]

No. Some compound bows were built with just one cam. I don't see them around anymore so I guess they weren't very popular. I never shot one so can't say how well they worked.

[@fultz.c92]

Nearly all Mathews bows use whats called SOLO Cam meaning 1 Cam i love mathews own 3 of them wont go to any other..

[@dylan_was_taken]

You're shooting off the wrong side, mate :c

[@tarasdoesdiy1999]

+Toxin I believe that there's no particular side he MUST shoot off of, but if he was shooting at a proper archery club, he might want to change how he shoots.

[@Gamerdude535]

+Toxin This would be fine if using a mongolian thumb draw technique

[@dylan_was_taken]

gamerdude535 true, i actually rewatched the vid to see if that's what he's doing but it's really difficult to tell when he draws back the bowstring xD either way, i suppose if he's still accurate it shouldn't really matter

[@danidaimondzofficial582]

sort of

[@eugenemorrill7009]

His pulleys are round so they are technically called wheels, not cams. Look it up.

[@johnwirk]

little tip, when cutting metal with metal, in your case bolts and ect... always use some type of lubricate, water, motor oil, ect...saves blades and prevents heat expansion of the blade causing more drag and pinch. Good job though.

[@cfong_sports394]

If youre left handed youre holding it wrong If youre right handed you put the rest on the wrong side Just saying

[@davidgierszewski2819]

this isn't even a compound bow the cams have no mechanical andvantage of a let off percentage that is the reason for compound bows
