man that is .....awesome. will you be presenting us with a video ?

what drill head would you recommend ? Any special kind ?[/quote]

Hey guys, I was just wondering if, when making my breech loader i could use a ball valve ? You know when you drill a whole through the side ? Yeah well i was wondering if you would be able to drill through the side of a metal ball valve. The reason why i ask this is because im not sure how i would d...

hey guys, Just got my first air cannon up and running with a 1" by 5ft barrel with a 3" by 3.2ft air chamber with a ball valve. Very happy with it and fires very well. but unfortunately for some reason the cap of the chamber began to leak air and cannot be fixed :( . so i've decided to buy a new cap...

hey guys, Im 100% stuck on working out the c:b Ratio thing in terms of how long my air chamber should be with a 1" by 5FT barrel ! Would someone be kind enough to work it out quickly for me i its not too much trouble ? And by the way the dimater of the chamber is 3" . thanks guys and i'll be sure to...

it makes perfect sence

just got ma pvc pipe for my 1st cannon of which is about to be build and i was woundering weather or not with the barrel being 5ft long should i have a long conbustion chamber or a short one ? or does it even matter

thanks guys

nah that was a diffrent design which apparently had no hope in hell

quite complicated lol to explain but here goes....... a 3" by 3.2m chamber with end cap leading to a 3" to 1.5" reducer, then a 1.5" by 5" piece of pipe leading into a 1.5" elbow then more 1.5" pipe then into another 1.5" elbow 90 degrees in total making a 180 degree bend lol........ then a 1.5" by ...

kk thanks. but im affraid sprinkler valve in the uk is a no no due to the fact that one one i need costs 100 pounds which is nearly 200 bucks.

ive got a 2.5" ball valve for about 40 bucks

well if ive got ..... 3" diamiter chamber which is 3.2ft long ( 1 meter ) then a reducer down to 2.5" then a 180 bend which leads to a 1ft of 2.5" pvc pipe then a ball valve ( 2.5") then a 4ft barrel. and pressure would be 100psi

would that work

lol no offence taken my dad has no idea what he's talking about

so ur saying it would work if i just had an extremely long chamber

diameters thanks

My dad tells me that to gain power ( pneumaticly) if ur chamber is say 3" u have to then have something like a 2" barrel otherwise it will have no power behind what so ever ? is this true ?

And if it is true would a convertion from 3" down to 2.5" be enough
