I will see if i can get a modded sprinkler valve off ebay. Unlikely, you're not at any great risk of finding them in a modded form on ebay - you'll have to do the modding yourself. However, if ebay fails for a basic sprinker valve, there are other online stores in the UK where you can buy them in t...

Yes make sure it has the markings NSF-PW or NSF-61, meaning its rated for pressure applications. You don't get NSF ratings in the UK, it's a US thing. It's probably worth referring back to the links in this post I made in the last thread... http://www.spudfiles.com/forums/viewtopic,p,211022.html#21...

^^ Yeh i had all the parts except the lighter... so cost = 99P. Dad said straight off he didn't want me doing a bigger combustion... so i will do a pnematic.... when i have the time i will work out a design. ^^ PVC pressure rated pipe is what i should look for isnt it??

My first cannon, yay!. I have only got 1 test fire so far... it was dark and i could only test one shot before i got cold. The potato i had in the barrel wouldn't move so when it fired the front end decided to shoot off... christ its powerful it shot the end accross the street.... i cant wait until ...

Ah ok, i get it. Well i shall start work on this later on tonight..... Im to busy nursing my toe nail which was just partially cut off. DAMN IT HURTS!

This is where if i had smoked when i was 13 i would be better off, lighters have gas???

Well mum will get me a lighter.... and i have my pill bottle and pen tube.... i have some drawing pins i will use to stick into the pill bottle. So.... do i just whack the lighter fluid into the pill bottle and put the cap back on and secure with sticky tape? How much should i put in? I don't want t...

Well i shall start slowly gathering parts for a 'ghetto' pneumatic cannon and i will make one of these mini cannons a bit later...

Damn.... i'm not old enough to buy a cigarrete lighter.... only 16 But all i need is a spark right? Hmmm.... i will see if my mum can get me one of those lighters..... spark hmm...... lol. we shall see.

So er, just to be clear on the little pill box one (which i might try in a sec) do i spray deodourent in the box and set it on fire with a match or spark or something similar??? *confused* .... im sorry, i am very new to this. edit - If you know of any instructions or can write some i would be very ...

I'm fairly sure i have nothing i can build a cannon out of.... Thanks for the links Ragnarok. Looking at a few designs combustion seems a little to big for my first project. Pneumatic cannons seem a better bet... Perhaps this or this if i am feeling ambishous. quick edit - Also, how am i going to pr...

Looks cool. I will see if i can find some instructions on the net to guide me ^^.

Thanks

Hey, i was flicking around the web when i came across this website. After looking at it a while i figured i should at least try to make a cannon. I don't really want to spend much money (i live in the UK). So what do you guys recommend as an easy or easier first build?
