Make a Shuriken out of a gear

In this simple-even-i-could-make-this instructable, i will show you how to turn the gear of your old bike into a fierce weapon!




- WarninG -

Dont do this without an adult, and dont throw your ninja star with anything or anyone around.
Dont do this if you are under 18! ( i`m fourteen but who cares )
Dont do this if you are mentaly chalenged please, or if you are just a dumbass.

lets get this little thing rollin then! ( look out, first instructable alert )

Step 1: Getting the stuff

Search trough your garage for some old bike-gears, you better dont use the ones made for racing because they are too lightweigt.

Get ones that fit your hand, i used small ones but you should use slightly bigger ones.

Now get something strong to jam it into while you use the electronic vijl on it ( i dont know what its called in English, so just look at picture 2

not shuriken! its a chakram! indian throwing disk!!

[verbosenutter]

Vijl is File in english, hope that helps!

[naruto the ninja13]

its a literal gear of war lol =P

[MisterHankie]

 That's not a gear; it's a sprocket.

[mikelewin]

he probably got it off a bike that out lived its service or at least a part's bin his father doesn't go through. he'd kill him for turning a Campy granny gear into a Campy "shuriken" lol. that could also be why he said in the beginning don't use ones made for racing. he probably made it, realized it was a little too lightweight for an effective weapon. i'd use shimano mountain gears myself, i got plenty and they weigh a little more

oi ju read here fixed, however, roof also Dutch are: P I also make weapons in my free time but never ged8 to un werpster or sow of un cog wheel (khep them had, however, made of stanley messen: P) I am VAT 16 and make hanging-post trusses hand arcs werpmessen werpsterren etc. I also collect weapons such as katana's, daggers, arcs and heleboel penknives<br/><br/>Used online translator xD<br/>So yeah us enlish can kinda understand what it is about now =]<br/>

[DeathByPancakes]

Ha, there are a lot of websites. And i'm taking german in school, so i can under stand about 1/4 of what u said

[camondascia]

a better idea would be to use a less expensive gear like from a basic ten speed and cut it so that the inside is what you use not the outside what you have there is a rael and no thats not a typo thats how its spelled the chakram is a disk much like this one but without teeth it has a smooth or wavy edge a rael on the other hand does have teeth and was generally not as sharp... but its a good idea and for all you morons that are going on about a weapon being worthless unless you use it on someone..... YOUR MORONS!! the point is for practice if you must. get a target and practice its fun and helps enhance accuracy i have been throwing knives since i was 7 and am now 23 and i can tell you anyone who feels that there is no point in owning/making something along these lines unless you cause someone else harm really should not be making them in the first place in fact the majority of you belong in a padded cell where you cant hurt the intelligent folk

[EnigmaMax]

... unless if you make them just to throw at fences (or my neighbors dog (Ha ha!))

[jongscx]

Why do you fight the fence? The fence cannot fight back...

[EnigmaMax]

do you prefer I throw ninja stars at people?

[jongscx]

Well, it will certainly raise awareness for the classic movie, Enter the Dragon, from whence my previous comment came from.... ...but only if they too can fight back. Attacking innocent strangers is like tossing darts at a cube of jello... there's no satisfying impact, only quivering.

[WurdBendur]

I don't know Dutch, but I assume vijl = file. But the tool you've got there, we call it a Dremel (the brand name).

[mysterious ninja of fire]

id do this but i dont have an old bike dont have the time and dont have a file lol

[smeata]

decent instructable. old idea (remember doing in myself when i was 12 lol) and no offence but yours isnt the best example of these i have ever seen. i imagine it would do the job it's designed for but i normally try and make my gear a bit easier on the eyes

[4th guy]

Just for your information. Real shurikens are close combat weapons which are aerodynamic. I'd like to see you fighting with a shuriken like that in your hand. :P (Looks cool though)

[codykage]

they were actually used for distracting the opponent/s. like a secondary weapon for a katana and so on. but yeh would be too easy for them to see where it came from if its a gear haha! and its called a dremel. nice instructable :)

[kingknight]

lets just be nice to dutch people ok alle nederlanders hier : hoi wat un k*t ding is dit seg d8 eerst dat die wel leuk was maar ik maakte er 1 en hij is gewoon kortweg k*t !!!!!MAAK DIT NIET!!!!! HIJ IS NA 2 KEER GOOIEN BOT (this text was only ment for dutch people) !!!!!!DUTCH FOR LIFE!!!!!!!

[sivion44]

ha, dutch...

[duck-lemon]

DUDE WHY DID YOU USE A campangyolo gear there real expensive

[duck-lemon]

no offence but it does say dremel on it... MALTA RULES

[pluish]

i ment it as a joke -_- , you should stop the chaotic internet talk, it makes you look like some thin ass geek = )

[azn_poptart]

ok i dont really care if its a chakram or a shuriken, as long as it is sharp, able to throw it, can hurt someone(like i would use it on someone[sheesh]), and its shiny

[romor24]

this is not a chakram for all who think it is...
http://en.wikipedia.org/wiki/Chakram

this is a shuriken.

[ginja_ninja]

i used it 4 hunting it works very well and im only 16

[grim3vil]

they are really cool & creepy

[hondagofast]

Somewhere, some poor dumbass has seriously injured him/herself while doing this...

[nar_uto_fan135]

this is ausome do u like naruto

[kozy501]

I like naruto. in fact i love throing stuff like ninja stars paper ninja stars, screw drivers, cut coat hangers. nails, frisbees. gears.playing cards. knives

[inertia18]

Go easy on the kid guys, but pls don't throw it to anybody unless you are in perfect danger!!. i tried this and its good!

[TheCheese9921]

sweet dude but Im 13 and you have to be a baby or somthing I do this crap all the time on my own and whats the point of having a ninja star if you dont throw it at people??? but it is a very sweet Idea ***** o and WTF? is up with people saying THIS IS MY FIRST INSTRUCTABLE WARNING WARNING I AM A COMPLEATE N00BER

[altaria1993]

yes you are a "N00ber" and you speak against yourself :) "i do this crap all the time" - if its crap, then why do you do it? "whats the point of having a ninja star (which should be shuriken, a ninja star is nothing...) if you don(')t throw it at people???(one ? is enough)but it is very sweet - eeh, first you say it doesnt have a purpose, and then you are gonna say its sweet , that is just shit talk, if you want to do cool, go stop talking like shit , if you now are offended, i'm sorry, i'm just correcting you. alty

[Intagra]

that is no Shuriken you made but a Chakram. a shuriken is a star like thing and small 2. a chakram like yours is a ring like chape. srry got dysleksie. and im dutch :)

[pluish]

hmmm, een chacram heeft geen stekels erop, maar is gewoon een soort frisby zondern binnenkand en wat scherper

[altaria1993]

a chakram is a half rounded ring with a sharper outter edge, so this actually IS a shuriken, just one that didn't exist yet, there are dozens of types more, search on the interweb :P alty

[pluish]

i know because of my learnings!!! :D

[rplatter]

Rotery saw blades work well and save you the trouble of making a point. They also have quite a bit of weight so they stick in DEEP.

[casvandegoor]

nice instructable! but the warning doesn`t help so much:

Dont do this if you are under 18! ( i`m fourteen but who cares )

but nice idea!

[donesixfour]

this does resemble a chakram but it has no proper name in the english language as of ye, that is if it is to be considered a chakram
