Introduction: Knex Crossbow
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!

Hi, here is the best arrow design for this. It's not knex, but it's super easy and flies 10x farther than I could get the shown one to go. You take a skewer put two pieces of duct tape on the end, one front one back, and then trim the duct tape. the arrow goes in with on fin sticking up, which is what the rubber band catches on.

A much better bullet is three horizontal orange connectors stacked vertically, connected to three white horizontal sticks, connected to another three orange connectors. You tie them together on each end with a vertical white stick. This has four advantages: (1) the bullet doesn't fall apart upon hitting something, (2) it runs smoothly down the track, not tightly like the bullet featured in this instructable, (3) the elastic band always catch the tops of the two vertical whites, and (4) the acceleration is down the full length of the track, not only half of it.

Going to make this. Looks awsome and range is good for a crossbow.

I like it, although maybe in the future, you could have your camara focus on the thing you want to present, like in how step 5, the rubber bands where out of focus

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.
