Breech-Loading Pneumatic Sniper
Posted: Sun Jan 18, 2009 9:33 pm
I'm stuck at my aunt's house, which is usually pretty boring, but thanks to wireless internet connections (using the neighbor's right now :laughing6: ), I decided to upload another cannon that I built a short while ago.
It has the standard sniper stock layout, using 1" fittings instead of 3/4" to make it more sturdy and for a little less flow-restriction.
<u><b>Specs</b></u>:
<u>Main Air Chamber</u>: 2" x 16"
<u>Barrel</u>: 1/2" SDR 13.5, sleeved inside 3/4" pvc for support (36" long)
<u>Fill Valve</u>: Rubber valve stem that I bought at Ace hardware
<u>Firing Valve</u>: Pneumatically modded 1" sprinkler valve
<u>Extras</u>: Breech loading ("bolt-action"). Again, another cannon with a paintball barrel lol
This thing was a pain in the a** to paint, mainly because I painted it with the sprinkler valve already on it, so I had to tape the hell out of it with painter's tape.
Overall length of the cannon is just over 5 feet long, and it's pretty hefty to carry around. I'd like to make a bipod for it sometime soon, but I'm currently in college and also working a part-time job, so my schedule is pretty much filled up lately.
Personally, my favorite part of the design is the elbows that I used to go around the left side of the blowgun to the chamber. It works out great as a way to keep the blowgun out of the way, and is still pretty slick looking. It makes the configuration of the trigger pretty comfortable, and provides sort of a trigger guard on one side so I can set the gun down without worrying that I'm going to accidentally fire it. Not that I walk away from loaded potato cannons, but in case I need to grab something really quick or whatever.
Ammo consists primarily of frozen paintballs, but shooting bolts wrapped in duct tape is pretty fun. Got the bolt idea from others on this forum. Simple, and has great penetration abilities
Anyways, I'll try to get some damage pics up tomorrow, but until then, hope the following photos tide you guys over
