I really like the frame/stock. looks clean. Is it just a long aluminum strip? I was planning on making one myself

Edit:

The rail is just 10mm aluminium flat bar.

Sorry I missed this comment.

since that is electrictal conduct pipe, is the OD the same as regular schudule 40 2 1/2"?

Hey,
I found online that lowes sells 2 1/2" schudule 40.But it says 2 1/2" rigid schudule 40.heres a link. Will it work to shoot tennis balls?

the only thing i dont understand is, can i still just hook up the fan to a switch and a batteray? Why do people have to put a bunch of stuff on a circut board

hey, Finally!!! My first combustion. Pretty plain and simple. A pezio grill sparker. A ghetto chamber fan :wink: (made from a 9v battery, a on off switch, a brushless moter from a r/c car, and a fan blade from a free handheld fan i got at a fair) . here are the specs; barrel: 26in. paintball barrel....

hey, :wink: i am happy to anounce that my first spud gun was a sucess :) .The chamber is a 2L pepsi bottle.My barrel is a 14in. paintball barrel. I have a coupling for a breech load system. This project took 5 min. to make and 24 hours to dry. My operating pressures are 10 to 50 psi. The tire valve ...

a really tight fit is good. right?

there is a store almost a mile from my house that sells 2.5 in. pvc.... but its schudale 80. can i still use that?

ok i also forgot to post this but i came back from lowes and discovered that the bell reducers are dwv. and so are the bushings!!!!!! so what do i use?

i bought SDR21 from a supply shop. i checked it and it said... 1 1/2" crestline SDR21. i dropped a golfball in it and it rolled down the barrel. is it supposted to do that? or does it have a firm fit?

ok so i'm making my golfball cannon after i found a supply shop near my house that sells SDR 21 (20 feet for 10 bucks :wink: ).my chamber is 3inch dwv pvc. BUT.. it's gonna have pressure rated fittings that are almost glued directly together.so it's almost a double layered chamber. in this order... ...

my next project is to make a stirrup pump. i wonder if i can get it higher than 150 psi. my compresssure cuts off at 80psi

ok thanks. ill just make a small steel cannon

hey im kinda new to this hobby. i have finished my first combustion cannon. it has a 1/2 inch barrel and a 2" chamber. but here is the question. the parts are all pressure rated, but in the winter (it gets around 30 degrees feirenhient here) is it still safe to shoot it?
