Please have your mother call me!! My phone broke long time ago and had her cell # in it. I figured she would have called me by now. I hope all is well with you guys.
i have a question did u pack the flash powder in or just put your fuse in pour in the powder and light it off? i wan to know how to light off this cannon safely with flash powder without creating a giant pipe bomb =P
@mw2isforpwners No you do not need to pack the flash powder! Due to the high combustion velocity of the powder, it is virtually unnecessary and possible dangerous to pack the powder. You will gain the desired effect without packing it.
@martyn347 depends on the cannon. if its solid metal bore, as long as its strong (and I mean really strong), flash powder would be good (and don't pack it! but if its something weak or very thin metal like pipe use black powder and pack it. black powder is safer but it won't give as loud of a boom. flash powder on the other hand will give and earcracking bang and you don't even need to pack it. hope this helped. if you need more info just feel free to ask and i will do my best to help :D
ok i dont think you understood my question, i was wondering how fast you think it can shoot a projectile in fps, not how fast the powder burns! i know flash powder almost explodes when confined and black powder can push a bullet out of a gun around 3000 fps for a high powered rifle, so im wondering if you were to put the flash powder in a bullet or cannon or something, and something with the strenth to keep the barrel from exploding, then how fast do you think it can propell a bullet?
A small correction, it is nitrocellulose(not black powder) that can propel a bullet to 3000 fps or more. Flash powder burns at around 2500 to 3500 fps at best when confined. Flash and high explosives react so fast that they will waste energy in deforming, exploding, or otherwise damaging the barrel instead of devoting its power to pushing the bullet. Hence it is not used. There is something called a explosively formed projectile (efp) I recommend for you. It is an ingenuous idea related to yours
i read somewhere that flash powder detonates or burns at 25,000 fps, so if you put flash powder in a cannon or bullet can you get a bullet to travell faster than the normal 2500-3000 fps in a high power rifle, or would the gun just blow up, but sy your rifle was extremely strong,can it shoot 10 times faster than a high powered rifle rounf that only has black powder in it?
Probally, but i have a feeling that it will explode. 25,000fps, i don't think that's true because, if it was this fast. On nearly everyones Youtube flash powder videos, the flash wouldn't be visible. Or, it would be a non powerful flash as not all of the light would be let in and that most cameras record at 30fps. I would say it burns at around 20 fps. If you want to measure in fps.
The easiest thing to do is instead making your own cannon go to Pyrocreations where Nathan did and buy the same one in the video!! I believe this the "Big Daddy Thundermug"???
This cannon was initially designed to be shot with black powder but like Nathan I've used Flash in it as well.
I used to pack it when using BP, but NEVER with 7/3 flash!!! I've shot it with 65 grams or just over 2oz. of 7/3 and YES the report and shock wave is AMAZING.
Hmmm, my best guess is that it was the initial shock wave. The mixture you used tends to have a denser and slower moving shock wave which creates more stress on the cannon. The mixture I use tends to have a less dense shock wave and moves at a higher speed thus damage can be reduced it not eliminated. Whichever way, it seems to be a structural problem.
I see the advantages of the powder you used though. You can gain a lower more "boom" like sound that many pyrotechicians strive for. Cool.
for one thing how much grams is 20 or 22 cc as u put it
second i have tried making a cannon with flash powder and i used 1-2 grams with a solid metal pipe 3/4inch wall and a 3/4 inch back plate welded on the dam thing blew apart the back plate went through the chair it was setting on also it was a neutral shot nothing in it no projectile
Hmmm, you make a good point, i should have remembered to add the gram amount to the description. When the flash powder was taken and put into the cannon it was very aerated or "fluffy" if you will. If I remember correctly it was slightly under 6 grams.
With the design of your cannon I'd say it was a structural problem. In many cases, with the amount of flash powder being used in proportions to the area of the inner chamber of the cannon and the thickness of the cannon wall it is easy to overload. To fix this look at the structure of the material being used, don't use fasteners or welds, and extend the thickness of the cannon wall.
Also when firing the cannon make sure it is placed firmly on the ground. The backfire from the cannon can be VERY powerful. DO NOT UNDERESTIMATE THE POWER OF THE CANNON. Also out of curiosity: What type of flash powder were you using? Was it the same mixture used in mine?
Amazing. Knocked the leaves off the tree!

Result: One hell of a shockwave. Probably would have set off ANFO.
