Introduction: Knex High Power Crossbow

Check out my new gun.Check This out.This is one of the most powerful single track crossbow on this site. It can go through 4 layers of cardboard and shoots over 100 feet straight. My patented ammo rarely twists or turns while it can still pierce very well. Please comment and rate. Look for version 2 in a few months. It will be even better than ever. The second video went through balsa wood and the cardboard.

Step 1: Barrel

A super strong and sturdy design.

Step 2: Handle

I couldn't take this apart but it shouldn't be too hard to build. Look carefully.

Step 3: Bow

The longest step.

Step 4: Support

This gives you an area to hold and strengthens the handle.

Step 5: Rubberbands

Use 2 strands or if you are strong and daring, 3.

Step 6: Final Assembly

Finally you are done with my best instructable.

Step 7: Destruction

Go crazy. Here is a picture of the ammo. There also is a missile and night shot. Do not aim a people as it will hurt.

Step 8: Grappling Gun

Shoots 30 feet and it is recommended to build multiples and then replace the whole thing instead of winding it up.

now, mine isn't as good as your version, but my crossbow that i made uses less pieces and fires pretty darn well. I might post some instructions on how to make my crossbow.

but nice one man!

Cool. Send me a message if you get around to making the instructable

dude last night i almost finished it after an hour and a half, and then accidentally pressed cancel...sucked.

i built it i made a mod to it and used 10 strings of rubberbands!!!!!!!!!!!!!!!!!! ;) :) i used a arrow in it and it made a hole in the trash can lol

do you have to use the blue spacers?

I notice the wood had a pre-made hole in it as well as the cardboard...

Yes but still, how did that hole get there. I only have enough pieces for this and it took me a month to build.

well it was worth one month

Yes it was. It was so hard for me to perfect the reinforcement. That took up almost 3 of the 4 weeks.
