Yea i guess it is kinda "odd looking" lol but i kept it "abstract" or simple so that there would be as few bends as possible to improve airflow. Its designed to be held like a modern armyish/bullpup rifle, with a buttstock (the 90* bend portion in the rear), a handle (kinda obvious, but the piece in...

Well i got bored waiting for the parts for my 3" porting 3000 cu in mega cannon, so i decided to build a copper sniper rifle. my first venture into copper mind you... [albumimg]276[/albumimg] Chamber: appx 3+ feet of 1.25 inch copper pipe (i say 3+ cause of all the FRIGGEN EXPENSIVE copper fittings....

Here are updated pictures of the valve, the chambers im still unsure of. valve sealed [albumimg]260[/albumimg] valve open [albumimg]259[/albumimg] better view of whole assmbly. [albumimg]261[/albumimg] let me know if theres any obvious flaws with this design, and ill ellaborate later. The design sho...

OK the time to order the parts is coming soon and i need a definate answer on this. Sofar i'm confident with the 3" porting piston, but design one has me using about a 1800 cu in resevoir, design 2 has a 3000 cu in tank. obviously i want to make design 2, just because it will be... bigger? haha why ...

Yea i definately agree about the "cooler looking" aspect, but wouldn't a larger port area equate to more power? I've also got a 3" port barrel sealing "X" or cross style valve on paper that looks very promising and cheaper, and thanks to some reading on the spudtech forums, pretty easy to make. so w...

Is there a need to syncronize dual barrel sealing "T" valves (i.e. "mauler"ish in design)? I'm planning on making my biggest cannon yet over holiday break and it will be rather big. to launch it efficiently i could either make a 3" chamber sealing "T" valve or dual barrel sealing "T" valves. I guess...
