Ideas Welcome- Piece limited Answered

Hey. Yeah, haven't really been k'nexing much lately nor do I think I'll be doing it much longer. Long story short, I'm taking college classes for my last semester of high school for credits in both and yada yada so I have more and less time. More because I don't have much homework and I only have one class on Thursdays which means an entire open afternoon but less because I'm a lot more occupied on other days with other activities.

But I decided to crack out the K'nex again. I need something somewhat innovative. Or maybe not innovative but just something that we don't have enough of. For example, an updated BAW was one of my ideas. The problem is that I have limited pieces. Take a look at my updated UMP, folding gun, or my BAW (red rodded stock version) for a general idea of how limited I am in pieces. So I'm obviously looking to make something compact. I was also thinking of expanding on my charging handle pin concept. Perhaps combine BAW and TBAG concepts for a shelled weapon. We still lack practical shell guns. As much of a hassle as they are compared to chamber action weapons and turrets, shells are still a perfectly reasonable (and more so, less complicated and less bulky respectively) method to get more range. But it's up to you what I build.

So any requests?


Shotgun shell was not pleasing. Went back to the shell gun. I decided to make it breach loading and with a normal pin. However, I only did so because I designed what I think is a new pin in such a way that it shouldn't break. I'm pretty satisfied with the front of the gun but now I have to figure out what to do for a handle and stock. I think It'll turn into a rectangular...thing... just because.

I might get back to the BAW2 (w00t 1337 for boss...sort of) but I decided I wanted to do something extra simple. I ended up making a new shotgun shell design. Well I made it awhile ago but I simplified it further to the point that I think you could modify any NAR to accept it easily. I'll get pictures later and perhaps a video of it in action if it turns out well.

shell gun sounds great.

Alright. Do you think they should be with removable mags and more similar to the BAW in construction or breach loaded and more like the TBAG? They'll both utilize a charging handle pin but in different ways depending on which style.

Not removable mags i reckon. a 6 round mag the fires blue rods or something would be quite nice. or even white.

Where'd you come from? And funny I actually started on a breach loading shelled blue rod gun but the charging handle I decided to experiment with didn't turn out so well so I'm going to redo it to use one more similar to my shotgun.

I was thinking of using whites too but the problem with them is that it's difficult to incorporate a magazine that'll both fit them and use shells. But yes, smaller rounds = faster velocities & less drag when spinning out = more range. I was going to experiment with this.

I only talk to the 'pros.' As in, around the time of KA. Every other knex can go die in a hole.

I reckon breach loaded blue would be amazing. And i f'ing hate magazines.

And, remember physics dear boy. Larger mass = greater forces = greater kenetic energy = faster velocity.

Bleh, I miss those days. Few are left these days. KI kind of sticks to itself like always. I haven't seen them around here for awhile. God knows what they're doing. Jacking off to their BRs and NARs maybe. (have I got your attention yet? I'm sure one of you KIers are going to reveal yourself and come out of lurking eventually)

Are we talking about the pin or the ammo? Physics say that with the same force transferring to two different objects, the object with less mass to transfer the energy to will move faster than an objective with more mass. Faster velocity = more range.

Same.. Those were the days.. Now modern k'nexers are like modern music. [insert swear word here]

I'm talking about ammo. But you do make a good point. Physics says 2 different things. MINDRAPE

Bleh, there aren't even that many K'nexers. Instructables is a lot less active than when we were around a lot. I remember the booming days.

It says one thing. You can easily observe this. Picture this. You're a guy who works with a consistent amount of force (not counting fatigue for example, right?) OK? So then you have two different jobs. One is to move a 50 KG bag of whatever 100 meters. Another is to move a 100 kg bag of whatever 100 meters. You're using the same amount of energy each time. However, because you have to move more mass with the 100 kg bag, chances are you're going to move a little slower because you have more mass to move with the same amount of working energy in your legs.

I'm assuming you know why ^ velocity = ^ range but I'll explain that too if need be.


Except that isn't an example of an energy transfer. The firing pin transfers all of it's energy possible into the bullet. Just like how someone kicks a ball.

Take this example. You kick a foam ball. Not very fast. Not very much distance. Then kick a real soccer ball (or 'football' if you're an arse) it'll go further.

And yes. That is elementry level math an physics ideas.

But that's due to different materials. Just do a simple test with a small, weak block trigger. Fire different rods and observe how far they all go. Smaller rods will fly further than larger rods. End of. You can make modifications with fins and such, yes, but by themselves, smaller rods go farther and that's all I care about.

That's due to the power of the firing pin.

If you do it with a weak gun. Yes, smaller bullets will go further.
However, take a decent br, then try blue and yellow rods compared to green and white. Because they don't have the mass (equalling energy) to overcome air resistance.

I like breach-loaders, if they're powerful enough to not warrant a mag.
Rapid-fire, or Power. Pick one.

Let's put it this way, there's a reason why we're using intermediate power cartridged, fully automatic assault rifles instead of full power cartridged, semi automatic battle rifles today. A k'nex war is pretty much scaled down and you'll see the very same things happening. More rushing, less sharpshooting. But I don't think I'll be making a war weapon.

True, but for a fun gun (if that's what you're going for), I think breach would be better.

And yeah, for war, you'd want a magazine.

It just depends on what you're going for.

Well I'm sure I'm going to do a repeater no matter what. I don't care for single shots. So the magazine would be loaded through the breach instead of being entirely removable. Just making sure we're on the same page.

removable mags if possible

combine BAW, TBAG to make a turreted shell ejector :D

shells sound good i actually looked into a month back but i didn't continue with this idea just cause i had other projects in mind but ive always thought that shells were cool

I think you can combine the UMP charging handle and your TBAG to make a good ink cartridge shooting gun.

go with your shell gun idea
