Knex Heavy Cannon v3 barrel strength upgrade

Check out my Heavy Cannons ammunition strength mod too!

Hi there! Here an 'ible to show you ho to make a Heavy Cannon V3 barrel strength upgrade. I heavily modified my Knex Heavy Cannon V3 barrel and some other things and the cannon is more than 2 times stronger! I actually added a second barrel on top of the normal upper barrel and lower barrel. This way I can extend the barrel over 20 cm (7.8 inch, 0.65 feet), and the most important thing is: The cannon is amazingly two times stronger so will not slap you in the face while loading what happened to me... This thing is just an amazing piece of work done by I_Am_Canadian, and I modified it :-)

PROS:
-Ultra strong.
-Amazingly powerful, effect and range.

CONS:
-High part use.
-Difficult to make.
 
NOTE: you can only use the mod in combination with my modded ammo , or els the red thing at the end of the ammo will break or come loose and also some other problems like that the cannon breaks in half and slaps you in the face, what is annoying and painful. 

You will change the barrel from part to part, until your whole barrel has been changed/modded.

Step 1: Remove a part of the upper barrel

You are going to change the barrel from part to part, until your whole barrel has been changed/modded.

You will take a 20 cm part (like below) from the original cannon each time, change it, and put it back and do this like 4 times for each barrel until your whole barrel has been modded. (See next steps) 

Pic 1. Get this part from the original v3 cannon.

Pic 5+6. Click off the two yellow connectors and do the same at the other side.
Pic 7. Get that thing off.
Pic 8. What you should have left.
Pic 9. The removed part.

Well, go to next step!!!

He's deleted his comment now, but someone with the username STAN followed by a number (Can't remember) but he was spamming and has spammed many instructables with his shotgun.

The newer versions of the Heavy Cannon aim to reduce piece count. This one increases piece count instead?
H1T4TCH1 (author)  TigerNod3 years ago
Yes it does.

Lekker boeiend ik heb toch genoeg stukjes (meer dan 13500) en hij wordt 2.5 keer sterker =)
Lol, okay.
