Possibility Of A Fully Automatic Knex gun Answered

I have created an idea (i think) to make a gun fully Automatic. Fully Automatic, meaning that you can hold the trigger and fire until the mag is out of bullets. I am pretty sure with some tweaking my idea will work but I have to get around to doing it. I would like some input or some tips as far as what to try. No I'm not going to share the exact idea just yet :)

well its been a wile and I have still not been able to test my idea so I shall share it and hope someone else can perfect It ( my grammar and spelling may be off, same with scientific terms :P) The whole Idea started with a Sniper Rifle I had made, It was a simple mag fed single shot, with a "bolt action" cocking system. It was fun, but it just was not enough. So I thought about peoples favorite topic on Knex ( or so i feel) which is being able to replicate the amazing power of Semi auto. So, after some thinking and some researching I divised a plan, When the Ram is pulled back, there are rubber bands providing a forward force, so, if you could get a force to send the ram backward when it is fired ( a high powered easy to compress spring was my idea) and then re lock, this would simulate the "blow back" of a real gun, In talking to a physics teacher, I ran into a couple problems, I would have to get the exact ration, other wise it would not work, or i would have to add another power to the spring. I still am in the proccess of testing somethings , but I have gotten a life, and not had much time at all latly :( so If anyone would like to try my idea and call it their own ( not recomended) you can, I would appreiciate if, sucsessful, I can be at least mentioned in the design of the new gun. :) thank you !

I have a new mech it fires 7 rps on full-auto I swear to GOD!! it use a rubberband for power not a motor so it can use a true trigger not a switch. Only thing is it uses a drum mag type thingy with only 8 shots so I find my self re-loading every like 3 seconds even after pulsing it. am trying to make it use a BELT!! so that means more rounds to shoot:)

I know what it is going to be. The Trigger pulls a cog back, and it allows the gears to move and the gun to fire

yea, it was the elementary schools end of trimester so i was like hey fine by me.

You must be in a differnt district, Because my little bro had school that day

Well to answer all of your Questions NO it is not anything that has been done before ... ive searched, but i have done the calculations and it is proving to be a possibility. It will be a normal looking gun, Probably a sniper ( i like snipers ) or a larger rifle. its all in the firing rod and the trigger that will make it Fully Auto as to my secret iam not yet going to share but i will soon. The only thing holding me up is I have to go to Home Depot :P

This has been discussed previously. A real fully-automatic gun needs to use the energy contained within the bullet / shell / cartridge to reload the next - something which is very difficult to do (with KNEX) Using motors it a different thing. L

Does it use a motor, wound-up rubber band, or preloaded bullets?

Please post a picture, and if it is simply a chain-fed gun, or rotating gattling gun, there are plenty of them already. It would be cool if you could take individual pre-loaded barrels and run them through a removable magazine. this system would make an awesome uzi. PLEASE POST PICS!!!
