Introduction: Knex Crossbow

About: ╔═╦╗╔╦╗╔═╦═╦╦╦╦╗╔═╗ .........║╚╣║║║╚╣╚╣╔╣╔╣║╚╣═╣ .........╠╗║╚╝║║╠╗║╚╣║║║║║═╣ .........╚═╩══╩═╩═╩═╩╝╚╩═╩═╝ I'm 18 and love to build anything. I love to share what I make and see how people mod it so please...

this is my first ever instructable so please excuse any hard to follow directions. this is my "piece conservative" crossbow. it has a range of about 30ft shot flat and 40-50ft angled. it also feqatures a new type of trigger that works really well.
p.s. please rate and sub!

also check out my combat/tactical knife at; https://www.instructables.com/id/knex-combattactical-knife/

Step 1: Bow

make/gather two of every thing although when assembling make in reverse
pic 6 make four 
pic 10 flip to under side

Step 2: Rail

pic 1 make three
pic 2 make two
pic 3 gather nine
pic 4 assemble like this
pic 5 add the two other rails
pic 6 add these snowflake connectors
pic 7 dont forget the blue clip
pic 8 attach to bow like this
pic 9 another veiw

Step 3: Handle+trigger

Step 4: Fore Grip

i know it  is too simple please elaborate and show me your own versions
pic 1 make two

Step 5: Main Bands

do exactly as the pictures show and you should have no problems

i used two 8in bands that r broken but u can put two 6 or 8in bands together and just anchor them in the same places as shown
pic 4 it is crucial that when loading, that the band(s) r placed higher than the notch in the connector

Step 6: Your Finished

now go out and have fun

Step 7: Who Else Made It?

First picture is of the creation by Blackhawk7992. The second picture is by mrknex3000 as well as the third being his new grip. If you build it please post a picture of it and I will put it in the instructable ASAP with credit to you of course, HAPPY BUILDING!

These instructions were confusing and hard to follow, please make a better one, because I can't make it with these

Make a video!!! I really want to see it working cause I think I don't have enough parts.

I will first apologize for being untimely in my response, and then I will tell you that I may rebuild the crossbow and put up a video. I will first need to do some pretty serious posting of other instructables of various sorts.

This is sick looking........I would build it but I don't have very many yellow peices

Great Bow but I couldn't make the firing slot cuz lack of pieces, I added it onto a design I had made earlier and improved it quite a bit, thanks

thank you very much, I appreciate your positiveness. The trigger was my own idea and I hope to build more innovative things, I would like to see more of your stuff as well!

Alright robin hood. lol this is epic. totally great instructions.

Better arrow design: Connect a red connector to the end of a grey rod, looking like an arrow. Then, connect a green connector to the other end of the arrow. On the green connector's other side, connect a white rod. This makes the arrow able to stay on the "runway" the whole time, and still have the rubber band grab the arrow.

sorry crazy late reply, could you post a picture of what you are talking about for some reason i cant see it in my head ':/

In order: Red connector. In the middle slot, put a grey rod. Then 4-slot connector, on the end slot. Then put a white rod on the other end of the 4-slot. Sorry I don't have a camera.

Well not to put you down or anything because I know how cool it is to get featured, but I think "Raz1r Knex Bull3t" has a point. I am a little surprised this got featured too. But I don't think telling him to make a good Instructable, get featured, then come back was really in line. He has made several good Instructables too. But congratulations on being featured, keep the Knex world going!
