Introduction: The TBBR- 2 Concepts

Picture of The TBBR- 2 Concepts

This is the TBBR-2's insides. and I want all of you to use the concept of this gun but don't  make it exactly the same.

Ram: For instance, the ram I believe the gun would look better and functuoin way better if the ram were a red rod this way there woudl be less pressure on the (Piston wheel) you could also make the piston wheel have  smaller radius ,witch would reduce the stress ,allow higher rate of fire ,and more power.

Barrel: If at this point anyone noticed I used the ZKAR's barrel and mag , Yes I did  it was the most ideal system for a full auto knex gun. If you decide to use a red rod sized ram the barrel will need to be way smaller and also must shoot blue or even white rods. (this may be a problem)

Body: If you use the red rod ram the body will turn out almost half the size...

Gear ratios: there's no way to be certain how much tourq you will need but the slower you gear the spinning around the more power you will get from the ram. In other words It will take some testing.
(you'll need a bunch of red and blue gears to do this, at least 2 blue and prolly 10 red for the whole gun.

Power sources: the best power source  you can get would be ether a custom motor and battery pack ,or a battery drill. (using the motor could give you many options where you want the handle )

Be creative I'm not the only one with ideas you could get some to!

does it use broken parts?

just one y connector.

okay,i might build it....
can you use a normal motor?

I think but it would be very slow. you're going to want to use a drill...

then i cant build it

I just don't get how it works.

The piston wheel on the last picture rotates like a steam engine, and every time it makes a full rotation, it shoots a blue rod out of the barrel. Very innovative, no?

But it wouldn't shoot very far would it?

TigerNod (author)Millawi Legend2010-01-17

I don't know, but I don't think it would get very far. To find out, I'll have to build one myself.

It got 15 ft easy but that was with a gray rod ram and a I'm sure you could get more with a red. so it is by no means somehting to look over and say heh I don't have the time for this.

15 feet? Are you sure you didn't confuse meters with feet? Cause' 15 feet would suck.

This could revolutionize knex weaponry. You sir, just made yourself written in the history books. I will try to make one into the shape of either an M4 or AK47, but no guarantee. 5* and fav'd.

Thanks dude ;)

Ah, yeah, about that, I couldn't get it to work. All it did was push the round out of the receiver, and just kinda stuck there.

how could you possibly get a realisticly shaped gun out of this XD? how many rubber bands did you use? (maybe try a turret I was going to)

So what your not keeping your promice to post no ones going to be able to make it from these pictures.

thats what i said i might be lucky to make one but the chances arnt high

yeah i know

I got bored of it ,it used a bunch of my knex pieces ,and I couldn't get it to work.

I wasn't going to take the whole thing apart and use a red rod ram for it.

I should have made a slideshow like this with my last machine gun attempt, the drawing is on Knex Concepts though. It was powered by barbell weights, a very immobile, but excellent source of power. I estimated that 30 pounds would be capable of getting 30 or 40 feet of range firing full auto.

LOL that's awesome. I don't know if the knex could handle that tho.

The knex could easily hold it up actually, the problem was the super complicated mechs.

if it turns out good ill post my version

No one can build from these pics

i am buliding soon its not to hard

Good for you.

and if it turns out good ill post

I didn't realize this post was from you and I saw your pic and I was like that reminds me of something :D lol

Awesome, a revolution in knex weaponary! Finally, a semi auto that could actually work ! I am impressed! I rate it a full five stars, and I'll subscribe for further updates on this beauty.

It looks like a keyblade from Kingdom Hearts, haha.
