New Firing Mech?

So I was messing around with my knex when i realized i had made a new (I think) firing mech. It works similar to a hammer on a revolver. To cock the firing pin you just have to pull down on the hammer. Its very easy to do with one hand so you can  dual wield. Range is only about 20 feet though. I'm planning on working on it some more so i will update soon.

What is the knex pump action mech, I understand how to do the trigger but I cannot understand how the pump attaches onto the ram and how it stays on the body of the gun. Has anyone got a picture or an easy to build gun which doesn't use too many pieces and demonstrates the mech well, I don't care about power or reliability, I just want to understand the basic principles of the mech

New slingshot mech/trigger

I want to keep this brief whilst still remaining informitive, please excuse hurried typing hey guys been playing around with knex and found a mech that works. camera cable still lost, paint diagram below instead. to load band is attached to anchor at front, rod it then push/pulled through mech till trigger clickes into place, pulled further and rod is removed, ammo carefully placed back into mech (hollow back) trigger can then be pulled to fire. resultant gun is basicly silent, only one band can be used at a time. plans for a repeating version are still sitting around in my head. sorry for brief explanation, was kinda busy seeya later

Seeking mechanical design help for an outdoor mech 'robot' build! Answered

Hi all, I am currently collecting car parts and I'm itching to make a mech robot (like these: What I really want to do is have it close to my garage door, inert and crouching, until a motion sensor picks up movement. Ideally three actions would follow: I'd like it to stand up, ideally with lights turning on, and shortly afterward crouch back down. I have a shop and can weld, woodwork and have a very basic electronics understanding. I think I'd like to learn about hydraulics (I was looking into a used motorcycle lift as an internal mechanism to get this thing to rise). I'm not sure yet how to set a delay before it crouches back down. I'm looking for any recommendations - this is the first phase of my research into this project!!! OK, thanks in advance! DAZU

I'm currently working on a mech but I need to get an idea on the interface system, so what would be the best fit for it?

Actually I'm working with a few others on this but (as you would expect) our funding is quite low. Right now however; we're trying to decide what the best type of interface system we could use on our mech (yes a REAL, FULL SIZE, WORKING, Mech.) and so I'm turning to the Instructables community for help. Thanks in advance, Jake PS: If you want in on the project then you can email me ( with a list of skills you believe could be useful in the building process and I'll get back to you asap or if you just have a question about it that's fine to. [edit] And to respond to my first (and currently only answer) thanks for the help btw, the motion tracking is a great idea and would help improve the user interface greatly. However, what I'm referring to when I say 'interface' is how you would control and interact with it, your reply was part of the answer and will (hopefully) be implemented into our UIS (user interface system). Thank you and I hope to get many more answers soon. Jake

Semi auto MP5K

Hello everyone, i am back agian, with something non generic. I've seen to many basic "slide action" and simple "pin-pull back" guns. Usually, replicas that look good, often can't shoot, and most ugly-looking guns have a unique mech. I decided to combine the two, and make a decent looking mp5k, with a semi auto mech. The mech is different from my semi auto vector's mech, because the trigger is much more stronger than before, and never breaks. This is an unfinished gun, so will post instructions later. Pros and cons: Pros: -semi auto, original idea -magazine with internal pusher -super good looks (compared to my airsoft MP5K) -I kinda perfected the front sight -excels in CQB in knex wars (if you are going to have one) Cons: -hard to pull the trigger -shoots below 20-15 feet -a lot of cut pieces -cut pieces are needed (unfortunately) sorry guys ;(

ZipDart prototyping help

OK, had an idea and went with it for my ZipDart V.2. Unfortunately, currently having a bit of a brain fart of how to put a ratchet mech in. I've tried 7 attempts, 3 have even actuated and of those three none were responsive enough to be at all deserving of the ZipDart name. There is a google photo album linked below of the mech area and the gun on a whole. Feel free to comment either there or here with any ideas or insight. The mech can be complicated, just so long as it takes less than a half an inch of actuation rod travel to actuate and is fairly strong. Thanks for any help--if anyone has any questions or wants any more pictures, just ask. Photo album

Hey guys, This is a transfer rifle that I made a few days back. It outwardly resembles the TR/NAR, but is totally different internally. It uses a true trigger mech that I invented, as well as a transfer mech that was also designed by me. It shot about 50 ft., but that was only with one or two old bands. It was really comfortable, and I would have liked to finish it, had I not taken it apart to build the NAR+TR8+ZKAR. Enjoy, and go ahead and ask questions if you have any. -The Red Book of Westmarch

Knex gun projectile propulsion ideas

So I'm looking for stuff beyond what has already been done. Pin guns are everywhere, slingshots are yet again pretty common, hammer guns have been made but don't have the same performance as the others, and then you have "rail"guns which have a shuttle that works similarly to a pin, but can have the track extended. We really need some new ideas here. I specifically do for my current gun as I have a wicked cool loading mech, but absolutely no propulsion mech and limited space to fit it in. Anyone have ideas that are completely different? If you suggest the following, because they have been done before, please try and make a mech that makes it more innovative still: deconstruction magazine multi band ratchet (multi shot slingshot: if anyone comes up with a magazine to replace of bands, kudos! Plz post dat ***!) a hammer gun that gets some f-ing range for once (we're talking 35-40+ ft without needing glued parts) Some ideas I've come up with that I haven't seen (and haven't made either...) are: enclosed trebuchet (probably spelt wrong, but google wanted me to say "Bucharest" so I'm just going to leave it as is) (an arm picks up a round at the back of it's arc, then comes forward like a hammer but doesn't rely on impact for round firing but acceleration instead) newton's compound cradle: a pin comes forward and hits a shuttle out of a catch, with that shuttle being pulled forward by bands so you have the impact acceleration, then even more from the other bands switchback: a pin comes towards the user, hits the bottom of a lever (hammer) which comes forward and hits the round If you come up with others, or mechs for these, please comment with your idea! Thanks, and let the innovation continue :)
