All metal shotgun

Unread postAuthor: frankrede » Sat Nov 22, 2008 5:41 pm

This is my latest cannon, it is very powerful and compact for its size. Lots of fun to shoot and ergonomic.
Chamber:1 1/4" sch-40 steel
Valve: 3/4" QEV
Barrel: 1/2" sch-40 steel
Favorite ammo: 4 marble scattergun shot

Now for some pics

I really like when it comes to simple designs. You manage to do it and you add the extra fun-factor to it. Simple, effective...what else? lol

Well, it looks a load of fun to play with. What PSI do you use on this thing? what do you use for a wadding? those QEV's are a lot of fun eh? I like how you cut off the bottom of the blowgun to make it smaller. I really wanna see some good damage pics. I think you should try about 50 BB gun BB's behind whatever wad you use, should be cool.

I am thinking a shotgun is on my future plans. I wanna build a gun that I can shoot clay birdies with.

I like to play blackjack. I'm not addicted to gambling, I'm addicted to sitting in a semi-circle.

I don't need wadding with the marbles, but for BB's I use a bit of shop rag

Getting those projects wrapped up huh Frank... :wink:

A workmanlike model you have here, simple and effective...and should last you a life time. Makes me want to throw one together.

Are you pumping this thing with CO2 like your recent PVC/sprinkler model?

You can tell how awesome a cannon is by the pressure used.

simplicity, hard to beat it... i was thinking of taking the 3/4" QEV off my PVC cannon and shoving some metal on it so i can use higher pressures.

My regulator goes up to 800 psi with co2...haha, I will probably only take this beast too 350 psi tops and probably run it at 200 psi most of the time.

You mean the threads?
Those are sealed by Teflon.

Nice little high pressure plinker :P

It reminds me of the one I built, I originally had the chamber backwards, but then it got too awkward to hold so I turned it around:

Can't wait to see those damage pictures :)

Not likely.... :roll: Where are you suggesting using duct or electrical tape on a high pressure pneumatic cannon?
