hello

I'm looking into building a semi auto pneumatic of small caliber. Has a semi auto been done recently for a reasonable price?

I've been looking threw the pneumatic show case but I haven't found any thing like what I'm thinking of.

So if any one could kindly point me in the right direction thanks for the help.

Edit:

I'm assuming that the answer will be a "No" met with a touch of criticism. I realize a pneumatic of this nature is going to involve a fair amount of hand fabrication requiring the use of tools more advanced them common power tools or exotic parts.

I have a few ideas but thats for the pneumatic section. I'm just doing a little reckon with this post. I hope some one has built one or some thing close.

i literally just saw a blow forward semi auto 6mm gun less than a week ago check the bbmg strafer section

Please just at least TRY to find stuff yourself.....................there is a SEARCH button, you know.......

Chimera, there is a touch of criticism, but because you didn't even look around much first. There are plenty of semi-autos that could be built in small-caliber, and-most recently- jackssmirkingrevenge's 6mm semi.

this is what Singuarity was talking about, although it shoots bb's, you could scale it up.

Happy Spuddin'

Windshrike, shut up. He did look by himself and he said that he did as well. He wants to make a pneumatic, so he looked through the pneumatic showcase. Unless I'm mistaken, which I don't think I am, Jack's gun was posted in the BBMG/strafer section.
Chimera, there have been a couple of pneuamtic semi-autos. Click the link "Home" at the top of the page and there are pictures and a link to Clide's new (ish) semi-auto golf ball gun. He has also made a very cool semi-auto paintball gun, which you can find by searching. Search for "Semi Auto", posted by PCGUY, in the Pneumatic Cannon Showcase and in the Showcase Area.

*sighs* Sorry about that, chimera, a couple of seniors were being assholes; theyre older but that doesnt mean theyre better. I had just logged on to Spudfiles and I.......snapped. noname, are you on Theopia?I recognized your AIM. Anyway, chimera, what is your intended use for this gun? What kind of projectile? Do you want rapid fire or simply less pumping? How are your machining skills? Have you ever built spudguns before? If so, what kind?

Thanks every one.

I was just looking at jackssmirkingrevenge's 6mm semi; very cool it's kinda what I had in mind.

I found a lot of cool ideas in the showcase but nothing quite in the size range I was looking at (that I found any way their too much to look at in a single night).

I'm actually thinking of using nerf darts so I really don't need much pressure at all. but I do need a loading system thats preferably not gravity fed.
I saw a "True semi" posted by PCguy but he never went on to elaborate on the mechanics of it if I remember... I've looked at so many in a short amount of time its hard to remember now.

I also saw the golf ball cannon very cool.

I used to be a member on the spud tech sight back years ago. Strafer were pretty new when I left I think lucky13 was one of the big developers of the design if I remember that long ago. They didn't really catch my eye never thought to look at them for semi auto ideas.

Actually when I left Joel's Rapid Fire Carnival Cannon was as close to semi auto as it got.

WindStrike Thanks for the apology very decent of you ...... ignore my PM.

I have built several guns. I was a member here back when PCguy put the sight together. Actually one of my guns is still here its the first hybrid in the show case and its the one pictured for the hybrid section. http://www.spudfiles.com/forums/cannons ... html#13305

Iwould like to make a semi auto pneumatic nerf dart shooting gun... kinda lame but I said I'd try to do it for someone.

As far as machines go personally I have a 12" swing Hendy lathe and a wesburry vertical mill a small metal shaper and a furnace for melting and pouring aluminum.

For nerf darts you could probably afford to use a simple blowgun as your primary valve to keep things simple.

As regards to magazine feeding, you might want to consider a spring loaded version of this design Spudinator had shown on SpudTech three or so years ago. He uses shotgun slugs but since they're not spherical objects the idea might have some merit for your nerf darts.

gp tp nerfhaven.com or nerfhq.com, they have some semi auto nerf guns there, homemade, and cheep, like 20 bucks, i have made a few, my user name is nerfer909.

...then surely your nickname here should be "spudder909" hehe

he did keep the 909 though, don't want to know what "blind" stands for but...

Anyway, that's a decent idea of Spudinator's, it's practical,relatively simple and looks as though it has the potential to do some damage.

Lead slugs in a 3/4" pneumatic with a long enough barrel are certainly nothing to be laughed at, I believe he managed to get them going in the 550 fps region with his hybrid.

, that's pretty good, but his hybrid wouldn't have been semi auto though.

Apparently the pneumatic wasn't too bad either, from his original post:

The power of this gun is purely bliding, it'll sling a slug through 2 peices of 1/2" plywood. It reloads (well, the chamber repressurises) in one second.
