Introduction: Knex High Power Crossbow

About: I have moved on to better things...aka YouTube. So I will most likely not reply to any comments, sorry for any inconvienience. If you have important questions, you can go to my youtube channel (MagmaRhino) a...

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.

    Actually I used to play Runescape and I traded accounts. That was the name of the account and I stuck with it ever since.

    Well that is true BUT the heavy cannons use 2 tracks and the Dragonfly actually doesn't have a track. Sorry but I'm not building any more crossbows of this version. I may build other ones though so keep your eyes open.
