Zip2 Final Prototype





Introduction: Zip2 Final Prototype

About: Hello. I'm JonnyBGood! I'm a college student who now has a degree in Mechanical Engineer Technology. (MET) (excessively worded to mean a person who builds stuff).I enjoy building K'nex guns and many other th...

Well this took awhile... 270 pictures on my phone later and I'm ready to post the Final Prototype of Zip2. Zip2 has changed a little since you've seen the preview. The changes were: preventing an epic fail from occurring (as seen in my youtube video) with a mag pusher, and reinforcing the rod that connects the pump to the barrel. More elastic means less rate of fire, but with each pump you can shoot twice so you aren't really losing any rate of fire. If you want more info about the gun, check out the preview.  Now for the main event; let's make Zip2!! Also check out a review by lucas_the _boss!  Note: This gun does not use any broken pieces, so please ignore any in this ible'.

Step 1: Body Layer 1

A relatively easy step, just follow the pictures and you should be fine. Make sure the black hinge joint is attached as shown. Notice how the white rod is attached in between the two snowflake connectors (a trick I learned on this site).

Step 2: Body Layer 2

Zip2 is an unusual gun made for a right handed shooter, so if you are a left handed shooter please build the parts you see in Layer 4, The main difference is (as shown)  trigger size. I built this gun so you can fire the closest barrel first and than the further one second. You can always modify the gun to your liking but this is suggested to get the full enjoyment out of the gun. Make sure the tan connector are placed as shown in the pictures. Any questions and I will be glad to answer them for you.

Step 3: Body Layer 3

Layer three is pretty much a dividing wall in between the barrels. Nothing two fancy here just continue on through. I hope Layer 2 wasn't to difficult because you're going to making something strikingly similar to it in Layer 4.

Step 4: Body Layer 4

Realistically this is the same as Layer two except for two little changes. Build the parts and continue on.  Note Left handed version uses the smaller trigger on this side! 

Step 5: Body Layer 5

Yeah! Add the final body cover and a couple of small connectors to keep this thing together and you're done.......with the body. Now on to the Handle. (I was beginning to get tired of taking pictures after this step so if anything is confusing please ask and I'll clarify.)

Step 6: Handle

A easy little step here. Attach this to your Body assembly. Note: I accidentally forgot to add a white rod to the handle. It's not structurally important but feel free to fill it in if you would like.

Step 7: Stock Layer 1

Oh, here it goes, here it goes, here it goes again. Here it goes again. A simple panel to start this off. (Note: I think this gun can be built with 5 rods but I'm not sure.)

Step 8: Stock Layer 2

Pretty easy. A few parts here and there. I was running short on green rods when building the stock originally so if you feel this is a bit primitive feel free to change it.

Step 9: Stock Layer 3

I found some green rods! Can you tell? Anyway this part was added to fill in the gap where the ramrods and support rods are. Continue following the pictures.

Step 10: Stock Layer 4

An exact copy of Layer 2. Easy!

Step 11: Stock Layer 5

Layer 1 all over again. The other thing you are making is the rear slide (thing that attaches to the pump). Make sure to build and assemble as shown. Finish by attaching the two small blue connectors to the end of the black rods that have the slide on them.

Step 12: Pump

I didn't break this down too much because it's really simple. Just build the parts and move on to the final assembly.

Step 13: Final Assembly!!

Now lets get this thing together. Start by putting that black and red rod through the hole in the back of the body as shown. Then attach the top of the pump to black rod, and of course, then attach the bottom of the pump to the top. Next move the stock close to the body but don't attach it until you attach the rear slide to the red rod. After that all you have to do is connect all the rods to Body and you're done! I added pictures on where to attach bands to you gun, but if you have any questions fell free to ask! Please enjoy my Zip2 and review it if you have time! I'd love to hear what you think about it.

    Thanks everybody for making Zip2 my most viewed and built gun on instructibles!

    I'm always interested in what you'd like to see in the next Zip so feel free to leave a comment on my orangeboard and I will definitely consider it!

    Also check out Zip3's official Preview if you haven't already.

    Thanks! I made this in response to be more war practical. I wouldn't use it in an outdoor knex war, but inside this will be a beast!

    Yeah I get it totally , if it weren't for my shortage of yellow connectors and green rods I would have built the Zip3 but soon I will get more and bulls the Zip3

    Sweet! When you get around to building it, check out KILLERK mods for it he posted on youtube. It greatly improves the performance.

    Great build , I think though I found the best ammunition , it greatly improvez performance

    First off, thanks for building! Zip is my favorite series of guns that I build.

    The ammo probably does better due to it mainly being made of connectors which lowers friction. I prefer yellow rods just because I have a other of them and they fly good enough for me. Plus I have a hard time firing any munitions that require green rods because I need those too build more guns.

    Hey man, I updated the review! Hope It's better than the original one.

    Oh it's much better! I was very, very thrilled at your review update for Zip2 and I'm glad you liked it as much as you did!

    Also you were right about the stock, the gun was mainly aimed at performance so the stock didn't concern me. Although the main reason was, I was running short on pieces, because I still had six guns at the time..... Anyway thanks again for the updated review!

    I have an approximate piece count a little lower in the comments. Its a pretty do-able piece count.

    Mine shot comfortably up to 30 ft. If you strain it you can get 40feet but it will feel like something is going to break. I'd still recommend building it!

    Ohhh! yeah it shoots yellow rods. Theres a video on how to load it on my preview of Zip2 so check that out too.

    Well that's interesting! I sized the ammo holders for yellow rods but as you can tell it's kind of multi tasking ammo wise. You can insert a pair of red rods through the top as well and use it like a breech loaded gun! I'm going to work on finishing our project tomorrow and I'm contemplating Zip4 or maybe Zip3Light (Zip3 with fewer pieces, a couple less features) Anyway I'll be building something, as always.

    Just a thought, wouldn't it be cool if Zip2 could shoot spread like a shotgun?=P Just a thought....
