Loading and Firing

Step 8: Loading and Firing

WooHoo! This is the fun part. Firing is the fun part to be exact.

1: Make these two bits
2: Another view of that one
3: Put them together like so
4: Your fuzzy Cannon. Pull the bottom two strings of elastics back and latch them on the back.
5: What that looks like
6: Pull the upper two back and hook them on the top
7: Same as the other ones
8: Slide that ammo down the barrel. Pull the trigger, so that the rod moves out of the way
9: Push the red connector into the vacated spot, and let go of the trigger. If all goes well, the rod will go through the hole in the red. Be sure it does before proceeding.
10: Take the elastics off of the back and put them on the ammo like so
11: Loaded Cannon!

Booyah! Now all you do is fire. You do that by pulling the trigger...

Use super glue or hot glue

I'm having a bit of troubleshooting. With 2x 4 tied 62's, the barrel will break in half. This is not supposed to happen, since you use even twice as many bands.

How do you mean the barrel breaks? Rails come off? Snaps in half?

Make sure you are using 64's, and stretch them out real well.

Sorry for my late reply. The top rail breaks off, the bottom rail breaks off, the trigger assembly is propelled towards the bow. I fixed it now by adding a huge amount of supports to the bottom and sides, but still I do wonder if this is normal.

I did use 64's for sure. Not 62's.

i love this cannon!! only the trigger broke so i duck-taped it. any stronger ammo, it explode every time i load anyway, thanks!

Alspolde when you load it or when it hits an object?

vlerky in reply to I_am_CanadianAug 6, 2010. 12:15 AM

load

is there any way to make the bullet stronger so it can withstand the power of this beast of a gun?

I_am_Canadian (author) in reply to Tug999Aug 4, 2010. 8:23 AM

Sure, just beef it up a little. It'll sacrifice range though.

just built the hand held cannon and i love it!!! i designed a larger, more powerful bullet for the gun and im working on a "shot gun" round for better accuracy. also for better accuracy, i built an atachable scope that looks dece on the gun. the only thing i dont like about the gun is the piece count, i had to destroy 4 of my knex guns to make it and only just reached the amount for the gun. i give this gun a 4.5 out of 5. keep up the great work kid!!!

I_am_Canadian (author) in reply to lphillips094Aug 3, 2010. 5:41 PM

Thanks! I'd love to see any and all photos of your version!

lphillips094 in reply to I_am_CanadianAug 3, 2010. 6:34 PM

i made some other attachable parts for your gun such as a bi pod, a stock, and a mono pod on the handle also i have built many new rounds that work differently i will try to post them all this week

i built this and it kicks butt!!!! I got mine with 8 strings of rubber bands to shoot 283 feet 11 inches!!!!! and trust me it took a long time to measure that. I also built the v3 nano. I gotta feeling that i screwed up though because i only got 16 feet 5 inches with that thing. anyway this rocks, u rock and your knex skills are da bomb!!!!!!!! and so r u. Peace out!!

Thank you!! Is it possible you have a video of that large distance being achieved? I'd love to see it if you could, I wound't have thought that distance possible. Thanks again for building!

NICE!!!!! i set up one of those mancalla things and shot at it and it knocked it over. havnt tried shooting anything else yet.

cecool says: Dec 18, 2009. 12:06 PM

I decided I would start off making the smallest one, to test it out,
it's power was... BAD
it's range was ... BAD
it's accuracy was... average to good xD

I've used double rubberband, as the single ones were just, worthless. I had to pull quite hard to load it, tough still it went about... uhm 25feet sais my converter(yes I'm european)

Rated this 2/5 because the trigger was really nice, and the system was tought out well, i guess it's range and power sucks because of it's size, imo it's not worth building.

Going on a vacation now, so maybe I will build the v1(everybody says it's awesome).

thanks for posting anyways

I_am_Canadian (author) in reply to cecoolDec 18, 2009. 2:14 PM

Power and range are really the same thing...

Sorry this didn't work out for you. I'm sure you must have done something wrong however, because this gun got over double what your getting with no trouble... Are you convinced you are using proper elastics?

cecool in reply to I_am_CanadianDec 18, 2009. 10:05 PM

I'm adding more rubberband, but I'm leaving in 4hours to the airport, altough adding more will be quite difficult
