Picture of Knex Heavy Cannon v3 - Nano
Introduction 002.jpg
Introduction 003.jpg
Well, this is the instructable for the third of the "Knex Heavy Cannon" line.

Anyway, this cannon is quite similar to the v2 in many ways. The differences are that the bow is smaller, the barrel slides are shorter, smaller and more piece efficient, and the trigger is a tad smaller, there are no wheels on the back (they are still on the front, though), and I got rid of a few unneccasairy bits. Range is 70-80 feet.

I hope you all like it! Feel free to ask any questions.

Enjoy!

I have made a few other versions of this gun. Check them out!

Wow. Just wow. This thing is amazing. I haven't gotten to test distance yet, but it tore a giant hole into a thick cardboard box, and wedged itself in the backside of it. Great Instructable, and great gun cannon thing. Great work yet again. Keep it up.

Thanks! I'm glad you liked it. Cheers!

You might try 4 chains of *6* rubber bands. I used five and on my second shot my gun completely and totally blasted into pieces... :( :( :( 6 worked much better, and my gun works great! :) :) :) :) :) 5 star work, I_A_C
I_am_Canadian (author)  JSF5213 years ago
Good idea, thanks!
I thought nano was small o_o
I_am_Canadian (author)  shoopdawhoop134 years ago
I hadn't planned on going smaller :-p

I_am_Canadian (author)  Brad G4 years ago
Yep, just tweak with whatever you have, and air on the side of caution, always :-)

What's a Emb Video code?
I_am_Canadian (author)  Pizzapie5004 years ago
Hey, Thats a very well made video! Best of luck selling!
Pizzapie5004 years ago
Well i'm going to try to sell it ok? I'll tell you if the copyright people arrest me. This isn't a copyrighted item and I doubt i'll get any issues. If i do, I won't blame anything on you.
I_am_Canadian (author)  Pizzapie5004 years ago
Okay. I might ask for a penny or two if it actually sells :-p
Pizzapie5004 years ago
Hey can I make a video of this shooting and stuff and post it on youtube? Possibly sell the cannon on ebay? I will give you full credit and link the instructions to this page and your youtube page. I might not even do it (Unless I have some time).
I_am_Canadian (author)  Pizzapie5004 years ago
I might want a bit more info on selling my models, we might bump into some copyright issues there...

But, go right ahead and make a video! If its good, I'll add it to the instructable.
Ok i'll make a video but it'll take a while. But you can get copyright issues on ebay?
I_am_Canadian (author)  Pizzapie5004 years ago
Selling Knex models? I'd imagine the actual knex company might disagree.
I wouldn't call it a "model" I would just say knex cannon or something. On ebay they sell ferris wheels or rollercoasters made already but not by the knex company's instructions. On pretty sure they didn't get copy right issues.
