LSDs Spudgun Of DOOM!!!

I have been planing this gun for a while now and got around to making it today.

Barrel: 100cm of 15mm Copper.
Chamber: 355cm of 22mm Copper.
Valve: Quick Exhaust Valve.

This Spudgun has the chamber running in 3 lengths to shorten the overall length of the gun. It has a QEV with a safty Ball Valve in front of it. To fill it up i used a car tyre Schrader Valvein a compression end cap, to not lose any pressure and set off the QEV I fitted a Ball Valve between the Schrader and the QEV. The outlet, and trigger, is a Blowgun which works increadibly well. The weakest part on this launcher is the QEV and the Blowgun which are rated for 10BAR or 140PSI.
The power of this gun is amazing compared to my older version with a Ball Valve trigger. It has not been tested for distance yet, or with very high pressures. The most I have took it up to is 40PSI as my compressor ran out of batterys, even at that pressure it can liquify a potatoe from 15m away.

The Whole Spudgun.
The Valves And Blowgun Trigger.
Gun From The Back.
Down The Barrel.
Front Of The 15mm Barrel.

Finally The Origanal Plans For This Launcher.

Any Comments Are Welcome.

The reason I like copper is I feel safe around it. I'm not fond of pvc with pnumatic or not, pressure rated or not, since my combustion blew up on me.

COPPER RULES!!!

ps Love your cannon demon very nice.

I'm the other way around. I feel safer around pvc than copper because copper bends really easilly and dents if you hit it with a hammer.

Nice cannon though it looks ultra sexy!

if it bends it won't break!! That's why copper is much safer.I use metal on all of my guns.

This is the new chamber design, its not noticably less powerful than the old spudgun even though it has half the chamber volume.
