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)  JonnyBGood2 years ago
sure bro, no problem :)
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 (author)  instructaguy2 years ago
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
im gunna use a small wheel and make it a bit smaller, thanks.
anres321 (author)  instructaguy2 years ago
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 !
yeh thanks for the reply i might make and i can make it a bit smaller, thats really inspired me.
thanks man im glad i subscribed your really helpful
BEAST!!!! man!! maybe you could mod it to make the base stabler?
for some reason the magazine wont connect
anres321 (author)  The Cannoneer3 years ago
you have to connect them with the y-connectores, be sure they are all on the right place :p
i tryed that....the y connector on the right(pic 5) goes in but the other doesnt
anres321 (author)  The Cannoneer3 years ago
Sorry man but i really cant see your problem. i could try to solve it if you post a picture...
cool

sa ne marche pas moi
anres321 (author)  ygeny3 years ago
qu'est ce-qui ne mache pas ?
can you do it without that big gear because i dont have one of them??
anres321 (author)  knexinglemon3 years ago
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 (author)  super knex builder3 years ago
the pushpin is just for pushing the bullet out of the gun,, if you dont understand the mechanism you must be more precise
errrr! I cant get all the peices on right!
anres321 (author)  super knex builder3 years ago
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
anres321 (author)  super knex builder3 years ago
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)  Abcwtfidontcare3 years ago
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

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!!!!!!!!!!!! ??????????????

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!
