Introduction: Project a V2

Picture of Project a V2

This is the improved version of project A. V2 has a better handle compared to the original(it was not that good) a better pin guide, a better trigger and better arms. I never did figure out how much power it could hold because I was using project A's rubber bands but it got about five more feet than the original =D

I like this design quite a bit, do you find the crossbow limbs increase range? I find they seem to with slingshot designs, but I've never tested them with a firing pin base.

I use it on pin bows because it is easier to change the power that is the main reason I use =D(forgot to mention it but im planing on maybe using your drum mag in a bullpup =D )

I would like to see that very much! I've done quite a few things with the drum mags myself and they work pretty well, they do take some tinkering though. I would love to see someone finally use them though. Make me proud!

LOL WHY ARE THEY SO COMPLICATED TO MOUNT ON A GUN.......I've been trying to make a gun that models a calico liberty 100 but it's so frustrating that i've had to take a brake for a while and work on other things, still thinking though.

Vortus (author)Johnhall442012-11-22

What I've done to mount them is essentially extend a standard blue rod mag into the round mag, so as they spin out they're forced up the blue rod mag. I'm working on something else right now, but when my pieces are free next I'll build an example and take pictures for you. May be a while though.

For the gun im working on every now and then, it has to have just a normall drum on top due to the design.

Vortus (author)Johnhall442012-11-23

Woah, looks challenging, I wish horizontal mags were easier, they'd be ideal for that gun. I worked on the idea for a while but it's a rather tough one to work with.

Johnhall44 (author)Vortus2012-08-15

I agree that they take tinkering to put on a gun, im thinking about how to make a removable mag style and have some ideas but i cant find much time to build due to school but i slowly make progress.

Thanks =D

PotatoCoffee (author)Johnhall442012-08-24

No problem!

TheAwesomestDude (author)2012-08-04

i would love to have instructions for this

im thinking about it =D


Vaetheon (author)2012-08-05

Dude this is really cool and looks better than the V1

Johnhall44 (author)Vaetheon2012-08-14

Thanks =D

Vaetheon (author)Johnhall442012-08-15

Your welcome =D

If i were you, I would add a credit to Zak for at least the handle and trigger area. I say that because they look very similar.

Johnhall44 (author)beanieostrich2012-08-14

sorry about the late reply(I just finished a trip)but i think i will do that now as of some how I couldnt remember who made it. Thanks for the comment =D

beanieostrich (author)Johnhall442012-08-14

No problem man. This gun btw looks pretty good.

Vortus (author)beanieostrich2012-08-13

When I started K'nexing many things I produced ended up being similar to something someone else has produced, that was 6 months before I discovered K'nex Innovation, and 9 before Instructibles. I find that the assumption that he would've seen any of Zak's older guns a bit preposterous.
On a less personal note on the same subject: Many K'nexers are leaving this site, or moving on to different hobbies than K'nex. By making comments implying "giving credit" it takes away from the potential feeling of achievement that can lead to more inspiration, and thus to better inventions. Yes I agree that stealing credit from another person is wrong, but if you're heckling someone's lime light over something as simple as a handle, which anyone could produce, it's downright degrading.

TL;DR => Ask for credit to be given when mech's have been copied, not bodies, handles, or simple design similarities.

beanieostrich (author)Vortus2012-08-13

Meh, that's happened to me many times. I'm sorry if the comment sounded "degrading" but it's the truth.

Johnhall44 (author)2012-08-14

I have been thinking about doing that sometime,but im making V3 of my mp5k =D

Johnhall44 (author)2012-08-03

thanks, i need to rebuild it some time to see what I can improve on it and maybe put a mag but without a mag it seems to shoot farther so its either ammo capacity or range. I also posted another crossbow that doesn't have a pin and has a folding bipod.
