I live in the south of the UK and am looking to build a second cannon using pvc but in wickes and BnQ dont seem to show any pressure rating on the pvc pipes

and two. the pipes are usually not as large bore as the ones i have seen on here.

any comments of websites or places , or something im missing would be so helpfull

I've never had anything to do with plastic launches but I believe this place may be useful to you.

cheers
ill check it out now

and it just to get an idea of a larger cannon
as i dont have weilding equipment or milling or lathe equipmetn so metal is harder in some ways

For a larger bore cannon, it might be easier to make a combustion, which only needs to resist pressure at the time of firing so you can get away with unrated pipe, and also it avoids the issue of valves which tend to get quite expensive as size goes up.

true
i just have a metal thing about combustion and the cost of the fuel and i know its cheap but just that something about it

and maybe the fact it runs out whereas air doesnt

maybe a future cannon tho

In the UK, if you want pressure rated pipe you'll have to go online.
pipestock is kind of expensive, but it does sell pressure rated ABS if you're really serious.
I would try uk irrigation (formerly TRS supplies) first.
kiowa is handy if you want some big pipe like 4" as you can buy just a metre at a time, fittings are a rip off there though.

I'd second Jack, big combustions are a lot cheaper and possibly easier to build, do you have a compressor? either way make sure you've got lots of room for shooting before embarking on a large build of either a combustion or pneumatic. I made the mistake of building a tennis ball hybrid and not being able to fire the damn thing anywhere it was so loud.

ok thanks ill check that out

and i think combustion is not quite up my street as it were yet.

and well im in the deciding stage of small paintball size launcher or tennis ball size

i can decide between the two

MaxuS has a rather nice UK built tennis ball launcher but it seems to have cost a pretty penny, he says the valve alone was 80 quid.
