This is the kind of work I do, I design pneumatic launchers, and me not having any money, I give the design to whoever wants it.

This is my most recent design, for a coaxial marble gun with full stock.

the chamber was imagined with 1.5 diameter pipe, and the barrel with 3/4 inch pvc

The design was inspired by the delisle carbine, pictured below

Normally I would make these in autocad, but for simplicity's sake, and so they would be visible by everyone, I just made a simple paint drawings

Enjoy!

I used a one inch diameter barrel for my bolt-action pneu. I got bored one day, took out a shooter marble and discovered it fit the barrel perfectly. Is this just gonna be a gun for sh!ts and giggles?

It is pretty much for "shits and giggles" it wouldn't be too expensive, being made of mostly plastic, but it would be decently powerfull, seeing as it has a relatively large chamber, and for more power just add a longer barrel.

At lower pressures it could also potentially be used for paintball...

Seems simple enough, I'd go for it.

But yea just about any idea we think of these days has been attempted or accomplished by somebody else. These are sad days... :cry:

Haha jook, i meant your gun when i said that.
Sad, but inevitable. All online communities have their creativity peak, then it levels, and everything from then on seems repetitive and boring to the experienced people. The unfortunate result is most of the older members lose interest and leave. I'm one of those members who's interest has dropped significantly in the past 9 months or so. The once highly intriguing forums do not appeal so much anymore.
We all just need to get ourselves machine shops in our garages and it would fix that. Then, the possibilities would be endless. :cry:

Yea we definitely do, but personally I don’t really have the time or money to buy a CNC Mill and Lathe or even better... Water Jet Cutter. Then learn how to operate the darn thing. You know there are people who have owned a Mill for 5 years and can't even produce a worthwhile product for the life of them? I can safety say 99.99% of the board members don't have the time or the money either.

But yes, I constantly dream of heaving a multi million dollar metal shop instead of a garage filled with a car I'll never get to run or crap I'll never need. :P

It might not be accurate to 1,000 yards and more like its full bore brethren, but to say that the DeLisle is a peice(sic) of crap is a bit rich. It was by far the best suppressed rifle made during WW2 and the fact that it continued to be used for much later after that, a testament to its design and performance.

The irony here being that the DeLisle Carbine WAS a modified Short Magazine Lee Enfield Mk III.

One of the first really decent suppressed weapons, and still one of the quietest, even today with advancements in technology.

Far from a "piece of crap".
Does that thing kinda look like a big cat to you?

No, more advanced fabrication of the same techniques will not result in any kind of advancement. It'll just be tidier, heavier and more expensive.

The kind of innovations needed are the ones that only come along because you're thinking about a problem in the back of your mind for days maybe weeks at a time.

Sometimes you end up with the solution to a totally different problem...


I've just come up with a cunning idea in the last few days to produce more power for a pneumatic while still using the same volume and pressure of gas.

Unfortunately it's not a free lunch in the energy department, there are trade-offs in other departments but its still worth the time spent imagining it up.
