(Model III pictures shown in intro)
Hey fellow iblers'! Today i decided to post the only remaining pictures of project Nerfrocketeer. This is a semi auto nerf gun completely built out of knex. It featured a magazine lock that worked with any standered nerf magazine and a single motor as a power source. Unfortunately like most semi autos range is a problem, which was also a problem in my first two prototypes. This model had a maximum range of a pathetic 1 to 2 feet. I figured with a little advice from Nerfocketeer, an experienced ibler' in anything that shoots foam, can't hurt so he hped me brainstorm what i could do to increase the range on the gun. The only thing I could figure out is more speed=more range. And with more speed=more gears. I could get that, but that also increased friction and the amount of torque I will need to get the wheels spinning. My largest prototype II was used many more gears and required three engines to spin the wheels just to get 3 feet of range. A foot of that range was before it left the gun so really only 2 feet of range.

Model V (two wheel model)
Well Nerfrocketeer's idea to use tape on the wheels to increase the contact area on the nerf dart spawned a whole new brainstorm. Nerf gun Model V has larger wheel on it, a tad more gears (2 to be exact) and now a slightly less pathetic range of 5 feet. I was the most happy with this model so far because the nerf darts acctually appear to be launched instead of dropping out of the gun . I enjoyed what I built for the project, but I'm not quite happy with the complete picture of it. Not only does it not look good (more like a cardboard box with a handle and trigger) the range just isn't, well.... threatening.  The only option I see now is more speed and I'm not quite sure how I would execute this, but I'll see what I can do maybe sometime in the future. To be perfectly honest this project and concept is very fun to work on and there's a heck of a lot of potential in this system so feel free to give it a try or suggest things. I'm planning for my next attempt to use a more powerful motor so I won' t have to use so many gears and maybe it'll bring a bit thinner.
 
Anyway please try or suggest things for this concept. If I like your idea I may dust off the old idea myself to give it a try.
Thanks for reading!

<p>can you make a video</p>
<p>Good job, looks good!</p>
<p>There is a a video of Model III on youtube if you want a good laugh. I never got around to making a video of model V though.</p>
<p>Saw the video, and lol.</p>
Yep XD. The model V was so much better just didn't have a video.
Hey, nice! I wondered when you would post this. Too bad it didn't do everything you wanted. :( Thanks for the mention! Hopefully project (Insert Name Here) works better!
Oh that project will deffinitly work better. Again to be perfectly honest this system is works well it just doesen't have the range to compete with a real nerf gun. I have a more powerful motor but to put it in the gun would require me to change the entire thing. So I kind of lost intrest in the fact of having to undo three weeks of work for one possible solution. <br><br>I'll deffinitly try this again when I am inspired to do so.
Indeed it will &gt;:D Good luck if you retry it!<br>
<p>I wondered when somebody would try this concept, I always have wanted to &quot;make&quot; my own nerf gun. Sorry I t didn't work out but, nice attempt.</p>
Thanks! I always wanted to make my own nerf gun as well. I did make one as you see here but it just can't compete with an actual nerf gun's range.
Yeah, well, nerf guns aren't made from knex :)
I'm suprised it doesen't say when I started this ible'! Well just so you know I think me and nerfrock started this around summer last year? Not sure but this thing is far from new.
