K'Nex Crossbow

This instructable shows how to build a working K'Nex crossbow. Please be smart when using this, it can be dangerous. I suggest not using sharp projectiles and not aiming at anyone. I have a few dents in my wall from early testing.

Step 1 Key

• Build: build from scratch, unless otherwise noted.
• Attach: adding pieces to an existing thing
• Details: nothing new, just a different view

Here are all the parts and names used in this instructables.

Nice new trigger system. It looks like the black chain link pieces would be pulled out of the orange connectors if they were pulled so much though. Also I suggest making a new bow (the spring as you called it) such as one powered by counter elastic bands. Check IaC's cannon for reference. Good job.

I can see you at least tried to put effort in it but TBH it's doesn't really have a good design.

[AlexWillisson]

 I know, but this was something I made on a whim and decided to make instructions. I'm planning on improving the design when I have time.

Also, this is only my first K'Nex weapon. I don't have much experience in designing them.

[DJ Radio]

You could have improved the design before you posted it?

[AlexWillisson]

 Unfortunately no, I was on a deadline. I figured it was better to get good instructions for a early design, instead of spending forever improving the design. I'm planning on upgrading the design and revising the instructions when I have time. I already have a few ideas for that, also suggestions are welcome.

[DJ Radio]

It's actually better the other way around.

[AlexWillisson]

 It depends on how far you take it and how long you have.

very good first weapon!

 Thanks!
