Knex Contest Entry: Concept 38F23

About: i like to mess with knex, i think they are a very creative kinda toy for people that like to build things of all sorts. i have a youtube account. its potpieism, yes its a dumb name but its hard to get a name...

Well here is my semi - failed attempt for concept 38F23. It looks good, but i ran out of pieces at the end so the stock is a little weird, but i tried, and i mainly tried to focus on the actual concept, so here is my attempt, i hope you guys like, i did this to the best of my ability and knowledge. I hope in round 2 we get a concept that works a bit better for me :P well, here it is!!!

-Looks good
-Tried my best
-Comfy handle
-Easy to pull trigger

-Doesnt shoot too far (Approx. 30 feet)
-I almost used all my parts (Mainly green rods, those were all used)
-Im scared of adding bands, because i dont want the mech to blow up, im currently using 4, and the bottom section bends a little, im trying to fix that still.

One more thing, I forgot to put this. But Credits to Oblivitus for the concept. And I'm still working on this, so it's not complete.

    its great, but at least u tried ur best and i give u credit for that. check out my semi auto vector!

    Actually not really. it shoots really good, but the range isnt too great. But oh well. Im not having any problem with mine, show me yours.

    I dismantled it to try a different rail mechanism. Hopefully it will cut out some of that friction. It's designed to hold 3 sets of 3 yellow rods though, so gives a decent spread but range suffers.

    Looks awesome man! You sure put it together quick.

    So did you ditch the hopper-feeding plan? That would be very hard to get working with this concept. Hope to see you next challenge!

    Haha, im quick when it comes to exporting ideas from brain to knex. Even though this isnt "my" idea, like using the concept required a little thought. And yeah, there was too much friction for it to work right, so i tossed it.

    And the size of this gun shows why I like Tr style and illogic style guns. And they get a 40ft range with 4 yellow rods. It's a cool gun but it doesn't have much bang per buck.

    Sweet. Does the slingshot box squeeze the ammo at all? Because that could be decreasing the range. And I know that TheDunkis didn't mention it on the contest but I'd like a quick mention in credits at the bottom of the page. Thanks!
