How Do You Design Your Knex Guns?

There are lots of innovative Knex guns out there. But how did you come up with the idea? Please share your story and methods! -Did you try endlessly to make something work or purely by accident did you come up with a great idea? -Do you draw diagrams or sketches before design, or do you just rip out your tub and start building Knex ? -Any particularly interesting stories behind a gun design? Please share!

I just build the frame according to the features I want, and the gun takes shape according to how I make the components here's a pic of my newest gun:
sucky pic

Considering it was posted literally 5 years ago when I started knexing I agree.

ive been intrested in knex for about 11 years and i used to build vehicles adn then i ran out of inspiration so i googled knex instructions and after alot of searching i came across this site and therefore found knex guns. i usually think of new designs randomly and they work 60% of the time
u mean six%?only 14 instructables so...u only tried 21.7777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777(TO BE CONTINUED) times?

um, well on big guns i make the frame first, and a rough version of the mec out side of the gun, then i work on fitting the mec into the gun frame, and go from there.

i am now learning that i need to draw a version of the mecs i come up with on paper right away before i forget. if i had done that i would have a huge book of all my mecs, posable and imposable.

i just come up with some idea out of no were. i don't know how. just happens. also i can't control it so i end up having it bug me during school were i can't get to my K'nex to build it. most of my idea happen right before i go to bed, so i try to lay the idea out before i hit the hay.

most of my other guns are really mods of other ideas or designs in disguise, take my rifle for example, believe it or not, it is really a heavy mod of the_burrito_master's crossbow, can you see it?
this is why me build real crossbows!

I've have been a K'nexpert for a long time since my fascination with them after my older brother got some. It started when Pizza Hut had a promotional thing where they had 4 miniature K'nex models that when you got all of them together you could build a hovercraft. So we joined forces and started racking up a big pile of K'nex to build whatever from. We had this subscription to a quarterly newsletter from K'nex that my brother actually won a contest for and his picture was put on one. We both have ADD, so engineering runs straight through our blood. He moved on to metal and cars and let me keep all the K'nex. I think I have been at it for at least ten years. If I were to count the number of K'nex guns I have made, I think the Red Impact was probably around the 12th to 15th reincarnation (some of the previous forms were quite interesting, wish I still had them), and the only one that has lasted over a year without me figuring out how to improve on it. As far as how I make mine, it's an ongoing process. Whenever I get an idea, I will make a hurried, flimsy prototype version just to see if the concept works. Doing this lets my brain go the way it needs to, and seeing what's wrong with the prototype helps get a serious model right. Structure and mechanics all meld together into what's absolutely necessary with no parts or space wasted. Once I have a clear idea what it's going to be like, my ADD sense takes over and I just build. Like. Crazy.

Were the previous Red Impacts really unconventional or something? What else are you building right now?
