K'nex show and tell

I was hoping to use this forum topic to post discussion and pictures of all K'nex projects I am working on. Feel free to post you own ideas and pictures so we can work on our projects together further advancing the K'nex community. My hope is that this will be a productive active forum to encourage and push the community to get better and continue to grow.

If you want to discuss more about K'nex jump onto KI chat introduce yourself be patient and if your lucky you may get to discuss your build with your friends and others in the community use the link below!

new firing pin and updated trigger for all interested. The new firing pin is the longest lasting pin I've ever built

I'm working on a longer lasting more consistent firing pin I may have got one figured out. I'm testing it by repeatedly shooting the gun with and without ammo to compare signs of wear to previous firing pin designs. Over the course of time the pin I gave you will wear out due to the band pressure. I'm working on extending the pins life by 3x or more.

YAY! I hope it turns out!

so far so good I'll test it out more this week shoot it hundreds of times and continue to test it out. So far do good. I has little to no wear after over 100 shots and is yet to fail. Which is an improvement over previous designs which after that abuse did tend to wear it down a bit and begun to show wear.

What is different on it, compared to previous designs?

I'll get a video or pictures up tomorrow if testing continues to show promising or continued good results

Great!

I've been experimenting with different ammo types for indoor or close range guns. I still want it to shoot a min of 100 ft but it doesn't need to shoot 250+ft as my TR8 with fin ammo does. That sort of range is overkill and not needed in a indoor close quarters fight. Velocity of the projectile, short range accuracy, and ROF, is more importanthan than pure range and long range accuracy in the close quarters setting. Oodammo is a good round has good close range velocity bit is limited inaccurate over distance and breaks easily upon impact of the firing pin or even the wall or target it impacts. After lots of testing the round of choice that meets the above requirements and holds strong is a blue clip and green rod attached. In tests with identical power and conditions the blue con green rod ammo out ranged, had equal to or better initial velocity, better accuracy, and held up better upon impact than oodammo or any other round I tested to date. I plan on making and indoor weapon to shoot this ammo type no saying how long it will take me to produce a final product but designs and ideas are in the works. I'm excited to work on other aspects needed in a war setting specifically an indoor setting

Basically the smaller the ammo, the less energy it takes to accelerate it, the faster it will fly out, usually the farther it will fly. However, it takes the ability to fly through the air without disruption, else green rods would theoretically be best. I can imagine blue clips help give just enough weight to keep them stable? The only problem is that they're still rather small and easy to lose in an indoors setting. And they're a misc piece, so I don't know how practical this would be for the everyday K'nexer, but it still sounds interesting, so I look forward to whatever you got coming that isn't -as- focused on range.

Also, curious, have you tested white rods with fins? They'd be pretty neat, like little darts. I imagine you tested different rounds with fins before, but did you go this small?
