Yes I can get 4 shots without filling, and more.. but there are less powerfull. I loose 1bar per shot.

For sure, up the pressure would be great, but I don't think i need more power ( your reaction is typically american :D ) and it would be very risky to put it at 20bar.

The two air tanks are some Water boxes ( to travel ... ), There are not made to resist high pressure.

I think I'll replace them by a 2Liter fire extinguisher. Then I'll be able to get higher pressures :P

Hey Xtazz! Ton canon est super! Franchement ca va me donner du fil a retordre pour le prochain que je ferais...mmmh. Je vois que ta chambre principale est en acier galvanisé, ca tient facilement 30 bars.
Tu devrais creuser tes projectiles a l'arriere, ils perdront moins en précision, et le gain de vitesse sera cool aussi !
Le corps de l'arme es bien fait, peut etre un pti coup de peinture?
Salutations du val d'oise !!

English version :

Hey Xtazz, your cannon's awesome! hnnestly that's gonna give me a hard time for the next i might build! I see your main chamber is made of galvanized steel, that can easily hold 400 psi. You should hollow your rounds back, you'll gain accuracy and speed. The wooden stock is well made, maybe a little paint? Greetings from Val D'Oise ! (30 km north of paris)

Good job!
I like the corpse, erhm, body..eehh stock thing.
Very funny translational error :P
Spudguns are not meant to make corpses do they?

Clever system of opening the bolt and supplying the air at the same time.

Also, your projectiles would work better if the tail was hollow, as they are they will just tumble without the benefit of rifling.


i agree and you can see this because of the flat impressions on that wooden board you shot but vary well done. if posible could you get a picture of the valve

that thing would be the bomb with a paint job and scope.
nice work

Tres beau, j'ai envie de voir plus de fusils que tu ferai, tres beau encore, j'espère :wink:

Good job man, its a fantastic piece of work, and it looks like a great deal of fun, but those steel bullets look like quite the labor intensive ammo.

Hell yes

These steel ammos are hard to cut and shape with the "millstone" ( uh ? )
Need nearly 5 minuts per ammo

While you're at work on the "millstone", grab the peu de foret and use it to creusez dehors la queue for stabilité accrue pendant le vol :D

I looked at the video again, and I love the breech opening/chamber filling lever, it makes it so simple!
I had a look around the french forum (I speak very little french), and I saw a lot of chambers like yours. Several were just water bottles with three strips of duct tape. Yours may just be ok to 11bars, but I certainly would'nt go any higher!
I will test if duct tape does anything to help whan a plastic bottle explodes, but I don't think it will help much.

On a lighter note, wow! The cannons in france are all of this quality. Many of them are absolutely fantastic. The combustions are mainly advanced, and most of the pneumatics are very ergonomic with small piston valves.

The duct tape doesn't help when it explodes, but it prevents the bottle from exploding, because it's stabilizing the bottle's surface
