Introduction: CM-10, a Bolt Action Knex Rifle

A slingshot type rifle with a removable magazine, my first idea for this was to design a slingshot rifle with a magazine, and the only way to do that is to use the semi-automatic version of someone else s or make a bolt, which i happened to do with a couple hours of tinkering.... I have not test fired it, waiting for new bands for an accurate result, however, with 6 rubber bands (3 per string, 2 strings) i shot a friend in his leg, with his permission (lol), and it drew blood... i wanted to see if you guys wanted me to post, enjoy the video... (i accidentally spelled my youtube channel name wrong, it should be Ukiarue, but its Ukiaure :(...)

That's AWESOME!!! Too bad I am almost 100% sure that I don't have enough pieces to build it! :.(

It looks like an HK-21.

instruct39 (author)2010-12-07

great! like kinetic said, it does look a little flimsy, but its still very good.

Ukiarue (author)instruct392010-12-07

its flimsy in the stock and everywhere it doesn't need to be sturdy, like if you swing it side to side it will flex a little, which im not sure whyd you want to do that anyway lol

instruct39 (author)Ukiarue2010-12-09

good point! lol

Kinetic (author)2010-12-05

Love it! Looks a little delicate but very good job.

dansdoc (author)2010-08-01

this is actually the most complex yet simple to make design ive seen on this site

Ukiarue (author)dansdoc2010-08-02

thanks :P

dansdoc (author)Ukiarue2010-08-03

your welcome could i extend the magazineget rid of bolt and do a rachet that holds as many rubber bands as you want and make it a semi automatic? bunny! (\_/) (o.o) (> <)

Ukiarue (author)dansdoc2010-08-04

i dont see why not, youd have to make something to prevent the bullets from spewing everywhere when you put the mag in though, something simialr to the thing that pushes them down now except rigid and doesn't move..

I LOVE IT ! way to be innovative!!

post instructions

Ukiarue (author)dansdoc2010-06-22

i disassembled, i did keep the mech, ill post that as soon as im done with a project im working on... ive also gotten more knex so i may be able to recreate the barrel then you and anyone else who builds it can just throw a stock on there lol

Raikou-san (author)Ukiarue2010-06-30

I want the mech.

Ukiarue (author)Raikou-san2010-07-07

awsome design

DJ Radio (author)2010-06-11

This looks like a good little mechanism you have here. Now if you didn't have to pull the band back manually every time, this would be much better.

Also, this would be better if you cleaned up the general design.

Ukiarue (author)DJ Radio2010-06-12

how would i clean up the general design?

DJ Radio (author)Ukiarue2010-06-12

Replace the stock with something like the Knexsayer's, then just make everything look smoother and not put random parts everywhere. TR is a good example of this.

Ukiarue (author)DJ Radio2010-06-12

i did replace the stock, i will post pictures if you want, and i could make it look smother but the reason it looks random like you said is because i had to add another layer (to both sides, basically two layers, hence the yellow rods) to the entire gun to make it more stiff to support more rubber bands

DJ Radio (author)Ukiarue2010-06-13

Thanks. The mech is very good and I feel the overall gun is better if the other stuff is improved.

Chikara (author)2010-06-12

sub+5*, nice build

Ukiarue (author)Chikara2010-06-13

thanks

Awesome first ible! I subscribed!

Ukiarue (author)Mr. Muggle2010-06-13

thanks

TheChemiker (author)2010-06-11

Very good, I think it just needs a nicer hadle and stock. Great job!

Ukiarue (author)TheChemiker2010-06-12

redesigned the stock, it was a spur of the moment build for that part of the gun, and i did make the handle a bit wider, it fits my hand well and can support the weight of the gun, as in me holding it just by the grip, the gun being parallel to the ground... any other suggestions? :P

TheChemiker (author)Ukiarue2010-06-12

Is the mech sturdy? It looks like the top might be a little flimsy. If not, then it is fine. That is some fancy mech!

Ukiarue (author)TheChemiker2010-06-12

everything is pretty solid except for the ... bolt handle thing lol.. but i cant reinforce it because of the lack of space, uts still stiff though, not going to break not unless you want it to

TheChemiker (author)Ukiarue2010-06-12

Ok, then I have no more advice.

Oblivitus (author)2010-06-12

Brilliant mechansim, this has great potential. I'm going to draw some ideas out right now. 4.5 stars and subscribed.

~KGB~ (author)2010-06-11

nice mech!

Ukiarue (author)~KGB~2010-06-12

thanks!

non problem!
