Hey I just built a knex gun that is full auto, its somewhat like kne s knex full auto
except I poweredit off a powerdrill and it empties 20 rounds in like a second Ill try to get some pics up, also I used like 6 rubber bands on it and theres still no problems. It shoots something like 25-35 feet.

try things yourself rather than asking everyone else! You could have got praise for invention!

Did you not read my previous comment? I said i didn't have any gears. Therefore i can't build this.Try being polite rather than bickering at other people.
I never bickered with you. I was pointing something that you had a unique opportunity to get credit for a new idea. It's hard to portray emotion through typing, and i now see it could seem agressive. DON'T jump to conclusions. If you have no gears, why did you even ask?

well,sorry my bad. to me you sounded a bit steemed,i didn't know you were pointing something out. i only asked because i'm not rich, i'm poor. and knex aren't cheap, they're very expensive in pounds. the prices can be anywhere from 50 to 100's of us dollars. i figured if i gave permission to somebody who has enough knex since their childhood, i would give them credit for the instructable, and can give me credit for the idea,if they want.
if yur poor how do have a computer?

look at garage sales or ask your neighbors. I got one from a someone 3 houses down for $8 and its almost as good as the one that I had had then.

50 rippin rocket motors in a row would probably be enough....

unless it was like a cog powered by a motor that would have enuf force to power a bullet far and if it did it would be a slow semi auto tthat fired bout everyfive secs

sry, but i dont think so, but it would be a good idea. the only problem would be that wen a motor starts, it takes a couple of seconds for it 2 reach maximum speed, so you would need to put the ammo after the motor was on for a couple of seconds... so i dont think so

i just thought it would be a good idea. i figured, if you used a powerdrill for a motor or two of them,you would have enough power. just so you know, powerdrills have strong motors. that's why they have so much horsepower, but it depends on what brand.
it might end up working, idk, but u wont find out till u try it, im just saying, IMO (in my opinion) i dont think it will work, but you never know... STORY TIME ON THIS TOPIC!!! 1 time, me and my friend were making a track 4 halotracks, and i needed a jump towards the end of it, so i tried adding a barrier on its side, my friend thought it wouldnt work, but he tried it, and ended up using it in his own track (and the track he made got featured on halotracks) if you dont understand the story, then dont worry about it... but still try it, you never know

i would,but i can't sorry. the reason for that is that i don't have any gears or motors. other than that, i have plenty of rods and connectors. If someone built it other than me, i'd be greatful and give credit. :)

No, Unless you could multiply the gears so much that it has enough force of a rubbeband.
