My new "sniper like" gun

Unread postAuthor: sssssbooom » Mon Apr 13, 2009 5:12 pm

I have been working on this gun for a long time now. And I think it turned out really good. The main chamber is sch 40 2in and about 20" long all of the rest is sch 40 1". With the paint job I was trying for a red tiger stripe look, and to make it tougher I put a couple layers of epoxy on it. It was the first time I have ever coated something with epoxy so it was kind of bumpy but that gives it a nice texture. If you have any questions I will do my best to answer them. Thanks for looking

Nice gun. The paint looks good. In front of the blowgun is that a fake magazine/clip or a handle? It's nice to see another person who takes time and pays attention to minor details. Did you block of the stock? I usually like to tell everyone what they did wrong, but I can't seem to find anything wrong with this one. If I was grading this gun I would give it a 10.

Edit: The damage is pretty impressive. How long is your barrel?

the fake mag thing was just for looks but it is a great grip when I stand up and shoot. I did not block the stock :oops: but I try to be really careful. and the barrel is 46" long (just measured).

In listening to it, it seems to honk a little. I would recommend a blowgun mod to improve the valve speed and maybe moving the trigger up to the "magazine" to shorten the length of the pilot hose.

Awesome looking job. Well done. :)

Beautiful gun, It looks nice, and It looks like it shoots nice, I especially like the bi-pod. I need to make one of those for my gun too. What kind of pressure are you using in that thing?

Yeah, I had trouble with the bi-pod. I used epoxy at first but it broke off and I gave up on epoxy so I used some zip ties and they work great. I am only going up to about 125 psi for right now.

My first cannon I made was out of copper. I like copper a lot better just because I like using a torch, and I plan on being a pipe fitter when I graduate. But for this one I did not have much money so I just did pvc. my next cannon I am thinking about is a copper co-axle with a wooden stock but that will be far in the future.

well copper is better than PVC but still I preffer malleable iron fittings... using them is cheaper in the long run.... you know you can reuse every part, mod the gun in several seconds or replace the main valve etc.

I know I say it all the time but malleable threaded fittings are the way to go

I had no idea when I was making it, but now I think maybe like an 1" of epoxy in side the pvc where the stock meets the tee's to the sprinkler valve. You know what I mean? But it would be hard.
