thanks for th photos pookydarts, they helped alot. I have just used a schrader an drilled a hole and expoy-ed it in place from the inside out. the epoxy is quite thick so im hoping it wont blow out when its dry :? anyway thanks foall the help fella's ill set up a new thread in the showcase whe its f...

Ok, i kinda understand, but not completely, have u got any pics that you could show me?

I will look around the showcase, thanks for help and patience mate

hmmm, has it ever blown up, and what psi did you take it to?

haha yeah i know that... but my 2 layers comprise of, 40mm pvc and an endcap, how do i put it through both without them being stuck together?

what if the fill valve is at the end of a chamber that is like, 80cm long and 40mm pvc?

thanks for the help, one last question, when you installed your valves with epoxy, did you drill the hole, then push the in from the outside and epoxy around them or do it form the inside out?

the threaded ones are the ones im after... how would i install an un-threaded one to a pneumatic spudgun?

EDIT: oops sorry didnt read the whole thing properly.... would epoxy be alright for a gun going no higher than say 120 psi?

Does anyone have any idea where i can buy a schrader valve in australia? and also.....how do i install it? thanks heapps

this is mad! one question tho..... if i was to use a 1 inch modded sprinkler to pilot this gun, what would the valve coefficiency, seat diameter, open time, dwell time and dead volume be?

yeah, i have already decided on my design, but what i wanna know is if there is anything that i have left out or any ideas you have to make it better??

I am looking to build my first pneumatic some time soon. what i am am thinking is this: a 40mm golf ball gun with a modded sprinkler valve. It will have a 1m long barrel will be an over/under design. I am not sure on the length of the chamber yet, but i want it to be the same diameter as the barrel....

ok, thanks for that. probaly better to not shoot myself.v

ok sweet as, also are there any dangers in pressurizing the chamber first? and any other ways u would recommend to load a pneumatic spud gun?

just like to say hi to the community and have a question. i have owned a couple of combustion guns before and have always loved pressing a spud over the barrel and slicing the potato to the exact size, just wondering, is it safe to use this same method on a pneumatic gun?? also, can someone point me...
