Intro: Life Size K'nex War Cannon
Here it is the best of the best life size (or almost life size) war cannon. Yes I know there are lots of knex cannons on Instructables but this one is different from the rest. It looks like a cannon. It will shoot 60 - 70 feet with 2 rubber bands ,and will shoot though 4 pieces of paper. This does use ALOT of parts so I took the time to take a part count so you don't waste your time. It uses a more simple trigger Then IAC cannon but it(kinda) uses the same mech.
wonderful distance 60 - 70 feel with 2 rubber bands
will completely destroy 3 pieces of paper
uses a lot of pieces
Step 1: Part Count
4 gray clips
8 small gears
I can't give a number of spacers. Because the number will differ for each person.
18 black hands
2 rubber bands
Step 2: Wheels
Okay you might recognize these wheels they are from IAC's cannon but I enlarged them by 5 times.
Step 1: build 2
Step 2: add rods to one of them
Step 3: Build 8
Step 4: connect both sides
Step 5: add rods with spacers to all of the spaces
Okay now do this whole section again.
Step 3: Barrel
Okay I tried to do this as good as I could but it was very difficult for me to make this part of the Instructable.
PIC 1-2: build this part (it is the front of the barrel) PC 2 is of the same part upside down
PIC 3-4: build this. It is the middle part of the barrel.
PIC 5-6: build . This is the back part of the barrel and the firing mech
If you can't follow any of this Instructable let me know on my orange board and I'll try to help.
Step 4: Connecting the Barrel
Okay now we are going to connect the three parts of the barrel we just made.
Pic 1: connect the 3rd part with the 2nd
Pic 2: now connect the front with the rest.
Pic 3: you are done with the barrel it should look like this. ignore the bow thing we will make that in a bit
onto the next step. >>>>>>>>>
Step 5: Body
Okay this is more easy.
Step 1: build 2
Step 2: build this little thing ( both rods need to be black)
Step 3: connect the last 2 parts we made together
Step 4: connect both sides with the red rods
Step 5: build
Step 6: add last part
Step 7: add gray rods
Step 8: add gray rods
Yay half way done!! onto the next step >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Step 6: Stand
okay. We are to the stand.
Step 1: build
Step 2: build
Step 3: connect both sides
Step 7: Connect the Parts
It is time to connect all the parts.
Pic 1: connect body and stand
Pic 2: add 3 spacers on each side.
Pic 3: add wheel and put however many spacers needed to fill the rod (will be different on each side)
Pic 4-5: now we are going to connect the barrel to the body.
Pic 6: Build
Pic 7: tie 2 rubber band together
Pic 8: add "bow" and rubber bands
Pic 9: build
Pic 10: build
Step 8: Loading & Firing
This is very easy
Pic 1: Load it like this.
Pic 2: pull rubber bands back and hook onto the ammo.
when you are ready to fire just pull out the pin.
You are done!!!!!!!!
Have a lot of fun!!
