@saefroch
Ohh, i understand what he means now.
Yes, i do think also that the pilot air flow would be restricted also.

Thanks.

@Gun Freak
Hmm, i like that idea.
It's like "MRR" 1" piston valve.
I will try next time when i head out to the hard ware store.

Thanks.

@metalmeltr
Not to sure....
Sounds about right though.
8.25mm lead balls to be precise.

Thanks

@lockedandloaded
Not to sure what you mean?
Do you mean the "core" inside the fill valve?
or .....

@lockednloaded Yeah, it's quite comfortable lauching this cannon. i hold the cannon with my left hand on the "Tee" bit, and support it on my Right Shoulder. this way i have a right hand free so i can actuate the pilot valve. Btw, chamber is 500mm long Thanks. @saefroch Ive taken the gun up to 160PSI...

@MrCrowley OReally? Im in Casterbay near Milford. Well Plans are that i Build a 2" piston cannon made from Metal also. And after MUCH research i hope i have all the knowledge i need to build a decent hybrid..Like yours :lol: Noise is o..k ... As long as i dont fire the cannon at my neighbours (i hav...

@jackssmirkingrevenge
Thanks for the nice compliments
And yes always room for improvement.
Thanks.

@MrCrowley ahh, yeah that was what i was thinking about the ball valve and also seems that the ball valve opens the piston faster. you can also hear it opening faster. Blowgun is like pppsstttPOWW Ball valve is like psPOWW Yeah, im up at Auckland also, im in Northshore. Good to know my idol was a NZ...

@Gun Freak Thanks for the Nice compliments :wink: Yes, there WILL be future improvments starting with the Sealing face port... Yes, i am aware that the pilot vavle is large, but when i had the blowgun connected to the gun it didn't give as much "recoil" as the ball valve... I very much enjoy the "re...

@jrrdw Thanks for the advice, i have now reuploaded the pics.

And it's good to be here.
Thanks.

@Gun Freak Hopefully i fixed the links.
Thanks.

Greetings ! This is my first pneumatic cannon. After much research on this fourm on how piston valves work etc. (credits to "MrCrowley" and "MRR" on their helpful resouces.) Although, the gun isn't perfect and has it's pros and cons. I believe it works quite well. SPEC Vavle: 3/4" Piston vavle. Seal...

WOW ! looks Really awesome.
Love your homemade trigger system.
Must of been expensive to make with all that brass parts.....
Where did you get the "bayonet couplings"?
i searched all over the pumbling store and they didn't have it.

Again awesome gun !!.
