True, but do they have standard diameters? The 5B Drumsticks, I believe, has a standard of .590"

I used the search function to see if anyone has thought of this and I didn't get any relevant results. So today I was bored so I decided to make some more ammo for my 1/2" barrel. And I got an ammo stuck in my barrel (disconnected from chamber) so I looked around for something to poke it out with. G...

I recall I heard that a ball valve and a 4:1 CB Ratio was good. The ball valve because it good flow and it doesn't have to be fast cause the water is heavy (probably more true if you have a lot of water like my cannon which was about half a gallon) and 4:1 because you need plenty of air to push the ...

Yeah, but I haven't been on for a long time. I do recall that this website is really close to instructables and super soaker central. How ever, I'm not currently working on projects that are limited to just liquids.

I've made plenty of water cannons. I've always just loaded the barrel with water O.o or just get a hose and a couple fittings to attach it onto a barrel? It's quite fun to shot this in water cause it keeps bubbling :) Here is the Peacemaker MK2. It was designed originally to shoot water, which I end...

Thank you. I'm planning to get some high rated tubing tomorrow so I can bring my chamber to 80 psi. I got my regulator at Harbor Freight. It refilled itself to 40 psi in about 3 seconds. I might make some nail darts but I haven't yet. I have an 8" metal rod (1/4" in diameter) and it has some tape at...

So I'm not too active on the forum much so Idk if I am copying anyone. In each cannon, I try to add in 1 new feature. In this cannon, I added in an air regulator in order to get multiple shots. I have pressurized this to 80 psi. Backpack: 3x 2" by 1.5' with fittings (~200 cubic inches) Chamber: 3/4"...

Well my barrel fits to my cannon (interchangable) by just pushing the barrel into the female.

Now that I think about it, you could just use a coupler, but wouldn't you be limited on the the length of the ammo by the length of the coupler?

I see in a way how my idea failed

I'm sorry if this has been posted before :( I'm not on too often here. My idea is to use a hot glue gun to make a breech. (1) So you get a sample of the barrel and you get a larger size pipe (2) Fill in the space (Inside the larger pipe and outside the smaller barrel [The barrel size you'll be using...

I don't know if reloading for a semi-auto has been a problem, but here is my idea. The picture will be able to explain better than I can in words. I'm sorry if this an idea already discussed but I was bored one day and was sketching stuff for a new cannon. The concept involves gravity and physically...

Dont fire directly at people. Just shoot it upwards and let it rain down on them. Have fun! Too late :P I got several compliments from adults and they asked questions. I met another spudgunner who made combustions. I did the opposite of what psycix said and no one got hurt at all. It was at 10-20 P...

Can't wait for sunday, it's gonna be a water war (For all the Thai people out there, It's Songkran)

Will, do it slides on the 2 T's and the piece between the two T's If it is scratching, I'll add padding

P.S.
It weights quite a bit (20lb+ probably):P yet I could run with it

How big was the cannon? I can't imagine this cannon breaking bones. Injuried for a few minutes/hours maybe but not breaking bones O.o The cannon had a 6ft~ 1.5" barrel and a 2.5ft 2" chamber. It was an over-under. The part that hit my foot was the two 2" elbows, which actually cracked upon impact. ...

This might help you
