marble shooting mini knex catapult

I know there are already a few knex catapults here on Instructables and mine might not be that much different from them, but I still wanted to add it an see what you think of it.
I do hope you don't mind if I make any spelling or grammatical mistakes, because I'm from the Netherlands.
Now continue on to the first step for a list of the parts you will need.

[jaberwaukee]

this thing works great

[dglover15]

add a spoon on the top and more rubber bands! it flys!

[me]

wow it's been a while since I built it and there are still people commenting, thnx I guess

[TheAwesomestDude]

I like the way you designed the catapult, i only have 1 sugustion, put a guard in front of the catapult so that it does not fall over.I had to do that or it would malfunction!

[doodleninja]

best knex one i ever tried !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[anihilator]

i put a locking mecanism and it rocks ! you can go to youtube to see it (sorry for my poor english, I'm french)

thats cool im building it right now

[dursa]

instead of putting the inside white connecters i used reds on the outside

[xbox1kid]

pretty cool ;p  fun to fire sneak attacks at unsuspecting siblings
7/10 nice job

[splodies]

i put like 7 ruber bands on it and can now shoot a marble across my living room. i love it

[benjgvps]

I might make this! Very well done! Though something is bugging me... What is that "MT Logic" thing in the background of the intro picture?

[jamesjames]

its a speaker

nice job on this catapolt! it's pretty damn stong, ive dropped it several time's ( on accident ) ive shot some pretty big object's from it, and it does shoot marble's pretty far/hard it's solid build, and picture's and tutorial are perfect!
very good job on this instructable :)
btw how did you come up with this idea?
were you kinda bored and dicided to slap togeather a bunch of knex, or did you see a disign in a book or something like that?:P

[me]

Thanks a bunch for all the positive feedback, I'm really glad you like it
and yeah I just got bored and slapped together some knex to make this:P
it's been a while though since I made it

[applejuice1998]

lol you are very welcome! it's a solid design.
when people are bored, they can come up with some wicked design's ;)
lol good job tho :P

[mosesscopazzi]

when you make it really powerful and mod it (like me) the throwing arm gets stuck but i found if you put a yellow axle to stop the arm from swinging down to far it eliminates that problem :-)

[Ry4n]

ermm good but when you fire it the bottom of the arm gets stuck between the 2 snowflakes

[blazedude22]

love it srry i took ur idea for a school prodgect but cool

[me]

that doesn't matter, I'm glad you like it

[geodez]

you stole my idea 3rd street saints i did the exact same thing

[bookmark]

interesting, but how do you load the marble? it would be good if you could develop a bucket for the marble

[me]

the marble can rest on the two green pegs at the end of the arm

[stormz76]

good catapult i put a livestrong band on i instead of the rubberbands. i also made a larger one instead of blue rods i used grey ones it can easily shoot a marble a good 50 ft plus

[3rd street saints]

this is a very good little catapult something i found handy was if you put a yellow pice on the middle purple part it stops the arm from getting stuck

[TheMoonMaster]

All you hace to do is add a white rod with ywo grey connectors facing opposite dirrections. Clip it onto the very front socket of the snowflake. Also add these yellow connectors and rods to balence it.

[me]

works great, thanks for the modification =)

I'm not a big fan of the K'Nex Instructables on here, but this deserves special mention for being well done. You have nice, clear pictures without distracting backgrounds, a clear parts list, and images that clearly outline every step. More people who post ridiculous K'Nex guns should take note of this Instructable. Well done!

[s0lekill3r]

Wow, talk about a stereotype. There are some very well made guns that have clear instructions here on instructables. All you have to do is sort through the other bad guns to find them.

[CameronSS]

Thank you so much for taking a positive comment toward me and skewing it around to turn it into a negative comment! I just love it when people accuse me of stereotyping, even when I am stating a fact that you agreed with!
</sarcasm>

[s0lekill3r]

Yes, I agreed that this instructable is good. I don't however like that you shot down all of the other k'nex guns out there. Maybe next time you should specify who and what you're talking about.

[CameronSS]

Where did I shoot down all of the K'Nex guns? An annoyingly large percentage of K'Nex guns have horrible iBles, although it has gotten better. This comment string is ridiculous and inane, and I will no longer reply to it.

[s0lekill3r]

"people who post ridiculous K'Nex guns" Although this can be taken two ways and I may have taken it the wrong way, it can be offensive. Basically saying that my hobby is ridiculous and is not needed.

[TheMoonMaster]

Great Instructable! Its easy, fun and really useful. The pictures were great and the instructions were very clear. I made a few minor changes so that it can be more powerful with out the arm jamming but other then that its great!

[me]

well please share them with us, because I actually ran into the same problem, if you put on to much rubberbands it jams

[dinky]

cool

[me]

thanks for all the great comments

[dsman195276]

good, nice, well done, and original = 5 stars!!!

[PineapplebobTheGreat]

Awesome. 5 stars
