:D I tried this awhile ago. *high five* for perfecting it

JonnyBGood (author)2012-10-10

I am making something similar to this but with a different mech... Your clip looks like it works better than any I have built for white rods so, if you don't mind, I'll borrow it.

anres321 (author)JonnyBGood2012-10-14

sure bro, no problem :)

JonnyBGood (author)anres3212012-10-14

It worked a lot better! I just didn't use the clip pusher thing. I made a hinged lid to it.

instructaguy (author)2012-01-15

make a bigger mag, then make it handheld, then it will be too good and can you make a version without the big wheel and the massive motor. i have the red box connected to the motor ,and the grey ones. so plzzz plzzz make.

anres321 (author)instructaguy2012-01-16

instead of the big wheel you can also use the smaler wheel and a normal wheel 2 times,, the mag is pretty easy to mod, just make a copple of mags and put them on top of each other :p

instructaguy (author)anres3212012-01-19

im gunna use a small wheel and make it a bit smaller, thanks.

anres321 (author)instructaguy2012-01-19

cool, the wheel is used for making the motor slower and much stronger so if you use just one small wheel it will probably not be strong enough. but you can always give it a try, this is just a concept for an automatic firing mechanism so go ahead and make it better !

instructaguy (author)anres3212012-01-18

yeh thanks for the reply i might make and i can make it a bit smaller, thats really inspired me.

instructaguy (author)anres3212012-01-18

thanks man im glad i subscribed your really helpful

stormrunner18 (author)2012-01-15

BEAST!!!! man!! maybe you could mod it to make the base stabler?

The Cannoneer (author)2011-10-28

for some reason the magazine wont connect

anres321 (author)The Cannoneer2011-10-29

you have to connect them with the y-connectores, be sure they are all on the right place :p

The Cannoneer (author)anres3212011-10-29

i tryed that....the y connector on the right(pic 5) goes in but the other doesnt

anres321 (author)The Cannoneer2011-10-30

Sorry man but i really cant see your problem. i could try to solve it if you post a picture...

sa ne marche pas moi

anres321 (author)ygeny2011-07-19

qu'est ce-qui ne mache pas ?

knexinglemon (author)2011-07-01

can you do it without that big gear because i dont have one of them??

anres321 (author)knexinglemon2011-07-15

I'am sorry for reacting so late but I was at vacation and was not able to go on the internet for 2 weeks :p the big gear is used for slowing down the motor and giving it more power,, if you switch the two gears your motor will be a lot faster but have less power :D you can do it with a small gear and an average gear but the motor will probably be to fast and will not have enough power but if you repeat that i think it will work so i mean - small gear -> bigger gear + small gear -> bigger gear

super knex builder (author)2011-06-30

I don't understand the push pin

the pushpin is just for pushing the bullet out of the gun,, if you dont understand the mechanism you must be more precise

super knex builder (author)2011-06-25

errrr! I cant get all the peices on right!

which part cant you get on ? look at the pictures first and then try to figer out which part you want to make first,, you dont have to make it in order.

I can't get the magezine on

look at picture 4, the first picture. at the top of that picture you can see 2 blue connectors. that is where you have to attach your mag,, in step 5, the 5th picture you can see 2 Y-connectors they have to be connected at the blue connectors.
I hope this helps

Switch around the big gear with the small gear for EXTREME speed.

anres321 (author)Abcwtfidontcare2011-03-05

yes sure, I know that !! buy first of al you'll need about 100engines to do that and then he'll still have not enoug time to put in a new bullet :D and all your knex will be destroyed

Knexman15 (author)2011-02-24

is it a catapult? i can not tell

anres321 (author)Knexman152011-02-24

no :D its just a weird looking gun but I didnt spent much time at the design, The system is more inportant to me XD

michiel123456789 (author)2010-11-08

Very Clever!!!

thx !! :)

DJ Radio (author)2010-07-05

This looks like one of the knex semi-autos a KI'er made a few years back. You need to give credit for the mag.

WHO CARES!!!!!!!!!!!! ??????????????

i !!!! LOL

~Aeronous~ (author)DJ Radio2010-07-07

Me and Visper made that mag when we where trying to make a mag which would fit a block trigger, and put it on the TR!

Sketch98 (author)2010-07-17

Only 1 problem, doesn't look much like a gun

H1T4TCH1 (author)Sketch982010-08-26

that isn't a problem, that's a con.

knexsniper123 (author)2010-08-21

it dosent work

anres321 (author)knexsniper1232010-08-23

why not ? mine does work, I know it doesn't shoot that far but it does shoot

go_time (author)2010-08-15

It looks nothing like a gun

anres321 (author)go_time2010-08-16

so what ??!! it shoots

Whaleman (author)2010-07-13

I remember making this back in 2007 when I was an hyperactive kid but not yet a drunk. Never did get around to making a full auto version due to lack of motivation/ non- crappy motor. There was more potential in rack-and-pinion.

Furloy (author)2010-07-11

loks sweet! 5

~Aeronous~ (author)2010-07-07

This is my new sidearm. LOL were the hell did you get a knex motor that size! Its HUGE! I want to build it but I don't have a motor. You are the new kNeXFreek!!!

anres321 (author)~Aeronous~2010-07-07

you can try whit 2 normal motors

~Aeronous~ (author)anres3212010-07-08

How do you get 2 motors to fit?

anres321 (author)~Aeronous~2010-07-07

I got the motor from 'knex all terrain trekker' i think this is the best motor from knex that exist

Seleziona (author)2010-07-07

looks actually decent! a few of the ones like this aren't very good. 5*

Mr. Muggle (author)2010-07-07
