Something I've been pondering, a .30 cal pump pistol based on the Crosman 1322, so I put a couple of potential variations to pixels approximately to scale (10 pixels = 1mm) In both cases the hammer valve is replaced by a piston that is slightly biased forward. The second one has a bit less volume bu...

7A310B0F-7133-45BD-850D-6A43AFB70666.jpeg Hello all I appear new to the forums, but I’m really not! I have been on here since dial up internet, and the spud tech site forums. Anyhow I stop in now and again to see what’s new here, and what badass things you creators have made! With that being said, ...

I really like that weapon and I had planned to buy it but they don't exist around here, at least for a long time, when I had the intention of doing so. Yes, the 13XX and 2240 series are probably the most popular and modified air pistols in history. A question that is interesting, to improve these w...

Hey everyone! Been lurking here for a while after discovering this place while doing research on a pneumatic cannon, finding solutions to problems, etc. Now that it's been designed, built, and tested a few times I figured I should post here. I'm going to break this down into parts/chapters to make i...

I want to show a test of the system for my new hybrid to repeat. I finished building it today, and it works fine. I have to sort a little all the elements that are currently scattered on the work table. I'm working at 5X for testing, and it will be at 8X when the gun is finished. The valve I use is ...

I leave the GIF here, to better explain the design. You have to open the image to see it as a GIF. Feel free to ask me what I want, if I can't be clear. Slowly, I will describe each component, those that are commercial and those that I built. 8-) The references are: A- Loading mixture into the combu...

Project update. 8-) I built the hybrid's wooden stock, I think it looked nice. I also finished everything about the machine itself. In the photos you can see the parts, the .25 caliber barrel, the bolt system, the piston valve with automatic pilot opening and closing of the pilot, which I described ...

Here's something a little unusual that I acquired a while back, it took me some time to play with it as I needed to make an adapter for a new chamber and it's only recently that I was able to cut non-standard threads on the lathe. I bought this one without any accessories and with an air reservoir t...

No sé sobre tu abuela, pero la mía definitivamente habría sido un peligro mayor para los peatones inocentes si le hubieras dado uno de estos :rollo: :D Well, I'm going to drop my black humor mouth. I'm actually going to build two of these to give to my father-in-law and mother-in-law, once the gift...

Sorry to go to the sewers, and divert the topic of the publication a bit. ;) No need to apologize, I'm here for the humor as much as I am for the ballistics ;) How finely have you tried adjusting the distance between the barrel and valve body? The problem struck me while looking at the photos, if y...

Hello people. I would like to share a project I've been working on for awhile. Its going to be an air cannon designed as an artillery gun for paintball games. Below are some 3D images I've done of the final vision (I do 3d modeling). Its going to shoot groups of water balloons at the opposing team. ...

Hello, I am looking to build my first combustion spud gun. I have found everything with a nsf-pw rating except for the bushing/reducer from 4" to 2" and the cleanout adapter and plug. I checked multiple hardware stores around me and websites and could not find anyone who carried these items with a f...

What do you think... What will be the next step in airguns? Maybe more pressure to achieve more power, or more autonomy? I think that the boys of 60 or 70 years in the future, they are not going to shoot with the same thing that we shoot. In aviation, they went from propellers to turbines, from ther...

What will be the next step in airguns? Maybe more pressure to achieve more power, or more autonomy? An interesting thought, one can compare to firearms where in spite of the march of technology, there is little difference between the cartridges fired by the guns used today compared to those used in...

I agree with JSR. I wouldn't expect any major revolutions in the airgun world, but instead continued incremental evolution and possibly changing popularity trends. You can already buy a PCP semi-auto that will shoot the wings off a gnat. What would really get me excited is the commercialization of S...
