Is this your first pneumatic? I think it's a pretty nice cannon! :) It's a shame about the DWV fitting on there, if that's what it is. Besides that, it's awesome for something built before you found Spudfiles. I'm loving the paintjob too. Very nicely done! I'm looking forward to seeing more of your ...

That would be amazing to see installed in a clear chamber :P If I could find the correct electronics without spending a fortune, I'd totally try to make one, since the schematics aren't very complicated at all. Or, if you happen to have an insane amount of cash lying around, you could order a Marx g...

Here is my collection :) Going clockwise from the top, spring-powered UTG AK-47, two spring Smith & Wesson 4505's, KWA Mac-11 (green-gas powered), spring UTG M3S Multi-Shot (shoots three rounds per shot), and a green-gas glock (not sure what model exactly). <a href="http://i119.photobucket.com/album...

I like the idea. Were the empty cavities in the grip for wieghts that were taken out? It'd look pretty nice if you still had the "grip cover thing" (excuse my lack of knowledge) and made holes for the ignitor wires so that you could keep the grip on it. Either way, I like it

Looks great for a first pneumatic :) Only thing I can think of; it looks like the reducer on one side of the sprinkler valve is a bell-reducer, and is probably DWV. But you most likely know about that stuff now, so I won't ramble on about it. I like the aluminum shroud around the barrel and chamber....

My story's the similar to Starman's. I heard of tennisball mortars from a friend back in 6th or 7th grade, from a book called Backyard Ballistics. There were also chapters in the book on two simple combustion and pneumatic cannons. From there, I just started surfing the web for potato cannon website...

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 ma...

If you live in the US, you can get it from Baskin Robins. That's where I get mine

Yeah, I thought of gluing the two halves together, but I didn't because I didn't want to have to wait for the glue to dry

With a nailgun, of course! The nails are really small, and if you look at the picture that's a close-up of the grip, you can see little divot things where the heads of the nails went in.

Thanks for the feedback

@ Ictchamp - I made the wooden handle myself. It's made of two pieces of plywood that are nailed together.

I didn't bother making some kind of breech-loader for this one. Just a muzzle-loader. I figured that the shroud was too robust to be threading on and off.

This one's been like, 95% complete for a month or so now, and all I had left to do was attach the handle to the body of the gun. The chamber is 2" x ~6" and the barrel is 1/2" SDR 13.5 x 16" long. I've been using a ton of the 1/2" SDR 13.5 pipe lately because I have a bunch in the basement that I fo...

Thanks for the feedback :) To keep the barrel centered, I cut off the top of a 3/4" plug and dremeled it down to fit inside the 3/4" pipe. I just cut out sections so it wouldn't restrict flow, and then drilled a hole in the center for the barrel to pass through. The support is epoxied onto the barre...

I just finished this recently, and it's a bunch of fun to plink around with in my yard. This is also my first (working) coaxial. :D The chamber is made from 3/4" pvc, and the barrel is a 12" long piece of stainless steel pipe. I'm not sure of the exact diameter of the barrel. I just went into Ace wi...

I like the stock! Did you make it, or salvage it from something? Looks cool 8)
