Ideas that never quite got finnished....
This topic is intended as somewhere to abandon ideas we can't seem to get to work.
Fully auto k'nex guns, new designs, ect.
If you finnish someone else's project or take inspiration from them, please post props.
Have fun,
Snipe

ok, i will. but most of them i ended up figuring out that they would not work . anyway, here we go: 1. automatic pistol, with no motor. "pistol" i use lightly, since the one non-working prototype was far from a pistol. anyway, the system worked like this: rubberbands are loaded on to two switches (one is located in front of the firing pin, one behind). and there is also one rubber band on the firing pin to start. what happens is when you pull the trigger the gun fires, and then the firing pin sets off the first switch, releasing one of the many rubberbands on the front switch. the rubber band pulls back the firing pin, and the second switch is set of when the firing pin reaches the back. when it hits that a rubberband is put on the firing pin to pull it forward and make it fire again. repeat. i abandoned the idea long ago after how long it took to load, the very small range it would have, and that it was way to complex to work. 2. i might as well post the DD-30 mech idea, since i don't have any time to work on it with my "other" project... the DD-30 was a machine gun with a twist, it only used 8 barrels(the prototype anyway, the real version will have duel rotating barrels, if i ever get around to making it). each barrel has a semi-auto rubber band gun trigger, that fires one rubber band down the barrel every time the trigger is pushed in (the rubberbands that are waiting to be fired reset the trigger). the barrel has a 4/5 round grey connector mag. when the rubber band fires it takes a grey connector with it, firing it. so each barrel is 5 shot semi-auto gun. times that by 8 barrels and you get 40 shots. the trigger system is real simple, all it has to do is slide a piece forward that makes the triggers move forward. i might post more later.

for the DD-30 do you mean something like this: http://www.youtube.com/watch?v=0GAUnuuBkW4

first of all, the first gun that comes to mind when you say that is the original AR-4 commando. now, you might be saying that the one i posted should thus be v2, but it is v1 because this is the first posted version of the commando. I have pictures of both guns (and ill throw in the sniper remix, it doesnt have a lot of hype)
It sucked. Sure it was powerful (broke the firing pin and mag one time), but it wasnt reliable. It jammed and misfired 70% of the time.

Okay, I'll start. You know how a normal slingshot/crossbow works, right? rubber band is stretched back and ammunition is slotted in front so that the band will catch on the ammo. I had the thought that you could replace the hook on ammo (like my Magnum Dart) with a sliding carriage of some sort. The idea being that the carriage would slot in behind the bullet and the elastic would accelerate the carriage, which would then accelerate the ammunition. Pics coming soon.....

Ok, here's my concept sketch, basically the block below the barrel holds the rounds in the magazine, stopping the falling out. The carriage pushes that down when it is cocked back, allowing a round to fall into the carriage. As this happens, the trigger rod pops up through an anchor point on the back of the carriage. as the carriage is released, the block shoots back up, stopping any rounds falling out.

that's not the same idea. We're trying to make a mag feed, not just another crossbow.
i've been wondering why you lot haven't done that yet, I'm not a Knexer but ti seems like it would be pretty effective, you realize that you'd have to top load anything like that for simplicity but it would be easier to autoload...

I just finished a concept gun that uses this design. works surprisingly well. I'm still trying to build a nice looking frame for the gun though.

built better frame, desined shock absorbers, final range: 30ft WTF? needs work....
Jan 20, 2009. 9:38 AMknexguy
says:
Shock absorbers would slow the carriage down before the round left it, meaning the last few milliseconds of the round's journey out of the gun are slowing down. Try it without the shocks, it should be more effective.

says:
I had the shocks in so that the carriage wouldn't destroy the frame of the gun on impact. i broke too many pieces that way...

Hmm, it is a conundrum. Looks like it could be quite a project. I might make a proper crossbow out of this.

Mag with no pusher. Gun credit to Mepain. Idea credit to ironman? (I think)
Oct 9, 2008. 7:22 AMLordSnipe (author)
says:
pusher? you mean the plate that pushes against the ammunition stack?

says:
Sorry, I worded that wrong. I meant it has a mag that doesn't stick out.

says:
ah. ok. interesting. to what purpose? just to get a better look?

says:
how about a parallel mag? the mag runs parallel to the barrel and has some sort of mechanism to push the rods down into the barrel.
