clide's take on semi-auto (now with animation)

Post questions and info about pneumatic (compressed gas) powered launchers here. This includes discussion about valves, ratios, compressors, and anything else relevant to launchers powered by compressed gas.

Thanks boogie. Yeah that is just the stock. It seals with orings inside the bushing and there is a piece of pvc rod glued inside it at the end. Oh, and if anyone is wondering, it will remind you in an unkind way if you forget to pull the stock out before pressurizing.

For the sprinkler valve thing you could just mount a slide valve on top :mrgreen:. They have some 1/8" ones on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 12677&rd=1 cheaper than mcmaster

Wow thats a great idea! Clide, would you mind getting dimensions of all the parts e-mailed to me ( Spudinator@gmail.com )? With a lathe and mill I might just have to try this, though maybe to a smaller scale. I may make it all aluminum. This, as stated by everybody else, is probably the best semi-auto set-up we have ever seen.

WOW that gun is amazing. Could you perhaps draw in your diagram where the pressurized areas are? also maby materials in your valve assembly. Awesome gun. Great video.

sure thing, incarnate.

--edit--

It would be better if I explained it to you online...do you have AIM or MSN?

I just saw the diagram, neat!
I could make an animated gif of the operation, if you get me a gif version of the drawing (JPG sucks for drawings).
[edit: Animated gif included. (If it becomes annoying I'll link it instead)]

GalFisk: Sent you one to your email

incarnate:Thank. Do you have access to a lathe? If not then you wouldn't be able to build it with the same materials I did. It may be possible to build it but you would have to be creative with choosing parts, but as you noticed, Mr. Plow's would probably be easier.

Spudinator: also sent you an email

Absolutely, after I figgured it out, the one I made was not hard at all to fabricate, just getting it to work was the problem! I have no access to a lathe, so I make all my cannons using only basic hand tools and an electric drill. Kinda sucks for me. Clide, your stuff ROCKS! I wish I could be half that good!

BTW- I havent messed around with my semiauto since I moved, but right before I did I fiddled with it some. I can now get reliably 2 shots a second, and I just found a cheap 3 way valve on ebay, so if I get it then I'll be able to update. I AM going to make it a tri-chamber design, like I originally intended...it'll be a while. My current project (2 completely customized AR-15s)is kinda sapping a lot of funds right now, though.

Awesome idea, very much props to clide for this design and influence... just a few questions...

1. Is this pneumatic compatible with portable air compressor?

2. Is it compatible with a silencer?

3. What is ideal ammunition, and/or could you fit a smaller calibre object/round in it?

Thank you, if you answer, doubble thank you:)

1. Sure, anything is compatible as long as you get the right adaptors. The ROF wouldn't be as high, but the gun would still work.

2. You should be aware that you could get in huge trouble if you get caught with a silencer. Even though it is not for a real gun, they will still come down hard on you. That being said, same as above, as long as you build it to fit then it will work.

3. I use paintballs because they are cheap and a nice size. You could use a smaller ammo, but you would have to scale the barrel design down. Like any design. It is scalable to whatever size you want.
