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 made it! (author)anres3212012-10-14

sure bro, no problem :)

JonnyBGood made it! (author)JonnyBGood2012-10-14

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

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 made it! (author)anres3212012-01-16

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 made it! (author)instructaguy2012-01-19

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

anres321 made it! (author)anres3212012-01-19

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 made it! (author)instructaguy2012-01-18

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

instructaguy made it! (author)instructaguy2012-01-18

stormrunner18 made it! (author)2012-01-15

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

The Cannoneer made it! (author)2011-10-28

for some reason the magazine wont connect

anres321 made it! (author)anres3212011-10-29

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

The Cannoneer made it! (author)The Cannoneer2011-10-29

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

anres321 made it! (author)anres3212011-10-30

knexinglemon made it! (author)2011-07-01

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

anres321 made it! (author)anres3212011-07-15

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

I don't understand the push pin

anres321 made it! (author)anres3212011-07-08

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 made it! (author)2011-06-25

errrr! I cant get all the peices on right!

anres321 made it! (author)anres3212011-06-25

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.

super knex builder made it! (author)super knex builder2011-06-25

I can't get the magezine on

anres321 made it! (author)anres3212011-06-26

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 made it! (author)anres3212011-03-05

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 made it! (author)2011-02-24

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.

Whaleman made it! (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 made it! (author)2010-07-11

~Aeronous~ made it! (author)2010-07-07

anres321 made it! (author)anres3212010-07-07

~Aeronous~ made it! (author)~Aeronous~2010-07-08

How do you get 2 motors to fit?

anres321 made it! (author)anres3212010-07-07

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

Seleziona made it! (author)2010-07-07
