Do you have (big) plans?

Hi there people!

So recently I'm seeing some comments like: 'Yeahh soon I have time enough to build something big/new' - like that.
And because of it'll be summer break pretty soon (for me anyway) I'm interested of some of you are planning to create something very big or new or something!
Actually I was hoping there will be new big ball machines, like Metropolis/Chaos or Calactysm (or something:))
If not, I just wanted to wish you all a nice holiday.

Nope, too lazy to do anything. But if someone could just help make my **** mech, I'd be working on that fully-automatic weapon. >_>

Tell me more about it, perhaps I can do something.
Basically, all I want is a repeating rubber band flinging mechanism but with a trigger designed in such a way that there is minimal friction while pulling the trigger. You know with the typical RBGs when you stack up a load of rubber bands and it's nearly impossible to pull the trigger because you have to push against all of them before the gun fires? Yeah, I want to avoid that and have it near effortless to pull. I've explained how I'll use this concept plenty of times but if you want I'll repeat.

Yeah, that trigger are indeed very annoying.
But if you're making a full auto gun, I would not use a rubberband-shooting mechanism, there is no way you could reload a fullauto fast and it wouldn't be usefull. Even not with a pump, because there are too much rubber bands. :(
And ehm.. were you being sarcastic with your 'I'll repeat'?
No, I meant I'll explain how the gun will work if you need me to but I've already done it a few times elsewhere. Anywho, the idea of a controllable fully automatic would be innovative if I can get the entire thing to work so just see if you can't help me with the trigger mech and you'll see.

Well you don't have to explain it, but just say where I can say your idea. Do you've a topic or something?
I'll just explain it quickly. Essentially it's just taking the gas piston concept from real firearms and applying it to K'nex guns. The left over energy in a shot rubber band would hit a part at the front to rotate and drive a piston back into the trigger to automatically fire the next shot if the external trigger is held in. With this system, the next round won't fire until the last one has already been flung from the gun.

I see, but due all the little parts and mechanism a rubber band wouldn't fly in the direction which you want it. And the mech that hold the bullet must be powerfull and will never 'unlock' so to speak if it will be hit by 1 rubber band...
Unless, I wish you good luck :)
Well that's why I wanted help! If you design a mech just right, one band could overcome the force of several others if you base the design on friction between the wheel and the trigger and not on forcing back the wheel until it "unlocks" the mechansim. My guess is that this would be using a sliding trigger and not a rotary trigger. I and a couple others have been fiddling with designs but I still haven't found one that worked just right.
