now i know how to build a full auto gun this mech can help me building full auto brickshooting guns
your mechanism is by far th most refined and sturdy i have seen.
Can i use a smaller gray wheel piece with 4 holes? Will it work?
I just made it and the gears jam up. How is this supposed to be used in a gun? I like your idea though. Thanks for the video.
Use rubber band around big gear so it is under pressure.
Yasyas Marangoz just like my life
Use the right runber ands not loombands.
@@Ledger_Lewis sad but true
Imagine building something that you don’t even know how it works
Simple But Rare Attachment There, This Is So Good Keep On The Hard Work
Thank you!
This is where it all began. This video is the beginning of the golden age of lego guns
Mathematics - Second Chance. Banging tune! 👌
If you leave off the trigger and put a handle on the big gear, you can use it as a turn crank gun
No?!
How is it working in the video?but thanks for the idea
I love all your mechanisms
I just wanted this
What camera did you use?
Soo at 1.39... can that piece be swapped with another one?
kan je ook een kleiner tandwiel gebruiken
You can use that rubber band for the bite out coin
Thank you, this is what I have been looking for

@@johncarlomojica2480 he's dead lol 😆
I'm not dead.
I'll be back soon ;)
Toch mooi hoe die beugelstiekjes toch altijd weer van pas komen bij t bouwen van lego guns :)
I'm making a Famas F1 and this will help a lot!
Thank you so much! Ive been trying to make this mechanism for almost a month.
Its so simple, but so cool
But I don't have that gear toth what tooth shold I use
The only problem is that whenever I put too many, it would hit the small gear and jam up but I guess I can make it hold a certain amount of rounds
You could also make an automatic by removing one of the red pieces, but it would probably grind the gears after a while.
I'm thinking one of the (++) shaped pieces that stop the small gear. But I'm not sure if it would work as I originally thought.
Uhh so I know I'm a year late but I don't have the thin red pieces so is there a way to make it without those?
I not an expert but maybe u cant try to use the the thicker red ones instead of the thin red ones but ur gun mec will be way bigger.
Thank for the amazing tutorial it helpt me out really much
Amazing bro
Do you have the full auto version?
Vet kicks!
can you use a smaller gear like the black ones?
Hey Don. Can you make a gun just like this, with a mag ?
is it possible to make with 2x2 gear?
The portion where there is a small gear with the big gear, it won't spin. I made it precisely as you showed, but it kept getting jammed or just passing the catch.
try adding motor with white clutch gear (24 tooth) to the small gear, and it will work!
Hey so I realized what I did wrong, thing is, I didnt realize for the mech to work you needed to supply pressure (supplied by the rubber bands). Worked perfectly, forgot about this comment xD
Ralphie Vigg Good job! Sorry for the late reply :p
Its kevin 183 mechanism on his blowback rifle
Awesome.best.ever.
can you use a smaller gear piece plz rply
so like full auto blowback but not?
Thank u exactly what i was looking for
this is a epic bullshit
Ill try with the smaller cog
thanks helped a lot
Gebruik je beugelelastiekjes?
Where did you get that huge gray wheel piece that spins? what set did you get it from? Please tell me
Search Glagolitic gear in amazon
Could I use a smaller gear? Like the one you used in your C96 Mauser? I don't have that size gear...
Jonah Telkan sure but not the smallest or one bigger
It works. Kind of. When I load three bands, the first shot shoots two because the mechanism slips. The second shot shoots 1 though.
Zach Durocher The mechanism can't slip, the rubberbands must have some space between each other
@@multidomar is there an exact amount of teeth between each band?
I'll try to built it later.. good work
cool. i used this to make an awesome lego gun. works great!!!
in which cheap sets can i get that 40 tooth gear?
Preeeeeeety cool
very good mech
El homunculo 55 Thanks!
Multidomar 👍
De meeste blokken heb ik,... behalve dat grote tandwiel -_-, ik g 't proberen zonder tandwiel :D
tnx I can make kevin183s semi auto guns now!
Or mine :p
Thanks mate, now i can annoy my friends
Haha nice :p
Can I put a 24 tooth ?
is it possible that this mechanism can be made with any lego technic vehicle set?
No. Not with cheap ones
thank you so much i needed this
thx guy
thank you , I have all the pieces for this :) !!!!!!!
Is it possible to use this mechanic for a gun that shoots lego? I am currently working on a minishark of terraria and I want to use this mechanic, as in game the minishark appears to be a minigun, but only shoots one bullet at the time and is quick firing.
PrashBricks Just try! ;)
It's the same buildstyle from what I do. Just try!
I have already made a mechanic for the minishark which uses 2 triggers. Now I am working on the outside, which in my opinion is a really boring job...
(By The Way, I am using LDD to design my gun, so I can't test it, which is dangerous, as I am going to order my parts...)
PrashBricks III How was it? Did it work?
I tried it, but it didn't work, so I used a different system!
Try using an L-motor. Create a mechanism that pulses a spin and and it should make that gun fire quick.
Where do you buy the tiny rubber bands?
From the dentist :)
Can u help me? It doesn't seem to work
This is leg(o)it

@@johncarlomojica2480 I am indeed still here. But blimey, 7 years...
@ Oh My Gosh What A Legend
What does it shoot
Rubber bands.
can i do this with a smaller gear?
maybe
An LDD file would be cool
Sorry, I don't have that, the tutorial in pretty clear
Where can you buy the circle that holds the ammo
I got the parts from different Lego sets and Brickshop
Ok thanks
I realized I didn't has any pressure on the top of the gear. BTW your videos are great! It's really cool how you make these!
Nice
Cool
how do you shoot whit it i dont get it
Check the discription for the "gun" link and click on it ;)
This doesnt work for high capacity guns, as the torque overcomes the trigger
yes, it is made for guns with low capacity
yup, that is why my blowback rb gun gun wont fire, DANGIT!
Can you help out, a mech that keeps a low profile that only is 1 stud tall like this?
I dont have that many holed technic pieces.
+ADMRILOAWESOME D just check out my other tutorials
I used it in my tavor 21
Can you use alternate pieces?
_ Contr0l Xtreme _ You could do that yes
where did you get the red Technic pieces? (what set)
The red technic pieces can be found in the Lego set no. 42048( a car set )
What's the name for the orange axle piece
Sorry for the very late reply.
It's called: LEGO® 6371442 - 41677 - Technic, Liftarm 1 x 2 Thin
Hey oak i got it from a technic truck set
I spent hours looking for those red technic pieces I found them but they are blue
riley toler they have different colors
its kinda hard to work cuz first you have to press the trigger outwards
did u ever made a gun with this mech?
th-cam.com/video/SnIk02Q1H8U/w-d-xo.html
?????
I can't seem to get it to work
alternitave for the 40 tooth gear plz
Ressel th-cam.com/video/HhmwOGkHCPU/w-d-xo.html
Then, how do we use this mechanism ?
RoyalAttack Check the link in the discription ;)
Multidomar ok thank you !
Will the mechanism work with a smaller gear???(not really small) pls reply pls pls pls pls!!!!
Same thing I was wondering. Like the one he used in the C96 Mauser
hhmm
In theory it should
can i use this to my lego gun?
Yes, and if you make a video from it PLEASE CREDIT ME
Klopt ik heb ze ook
i tryed the mech and i cant load it
I have a shit ton of the tiny ass gear and I just have all the peices
And I don't have the small red 1x2 technic pieces..
_ Contr0l Xtreme _ Hmm, then you'll have to change the design I think
i buy them from WalMart
IDK
Ok
Thanks! I subscribed u
RossBuild LEGO No thank you ;)
***** so, unsub
RossBuild LEGO ?

awsome!
It's been eight months... what is this guy up to? Making a crazy good gun? Idk.
The Mythical Sponge I'm currently studying on university, very busy :(
what kind of music is?
Mathematics - Second Chance
Absolute banger of a tune!
Don't have parts, looking for a semi auto design that doesn't use those thin technic pieces
its more complicated than it should be
Doesnt work, to us, it works becausr our force is stronger that rubber band, so when we use rubber band, it doesnt work, he didnt even show us use it with a rubber band
