Air2theBrain too, and its starting to crop up on airgun forums. I bet Western manufacturers are a little nervous of this thing catching on, compared to their own wares which sell for 2-4 times the price.

And can I recommend a 3kpsi pressure washer gun plinker. More satisfying than you think.

Show us! Something like the one I had cobbled together?

Almost exactly, except I modified the trigger so it was a one finger affair, but left the whole guard intact. And used a small cobbled together chamber. 12" barrel tosses .22 air rifle pellets at 900fps, so I'm happy.

That's pretty good for a footlong!

I do have a uhhh, 3:1 CB ratio, so good "performance" is guaranteed.

Incidentally, thoughts on a good pilot valve for such pressures? I'm playing around with a lapped HDPE seal for a piston valve, but the lack of convenient pilots is difficult. I don't want some plumbed nightmare linking a pressure washer handle to the pilot.

I'm grappling with the idea myself. Gippeto had used a PCP style hammer valve for his awesome project, I'm torn between that or a balanced spool along these lines that would vent the pilot chamber into the barrel:

Like I said, me getting one isn't really earth-shattering news.

Still, as far as spudding overall, it's pretty cool. For the price of a decent track pump, you're getting something with quite a lot of volume per stroke, but with an insane pressure ceiling. It certainly makes high pressure launchers (or even moderately sized medium-high pressure launchers like HEAL) a lot more viable.

I have to admit that I'm a little guilted by the ethics of purchasing something that's plagiarising someone else's design work (China as a whole does not exactly have a particular reputation for integrity on that front), but I suppose that it's not something I'm going to lose much sleep over.

On a note not very related to any of the above, I may at some point try discussing one of my current art/story projects with you lot, as it does have a strong element of experimental weaponry, advances in warfare and international laws of war, and such things are somewhat within the idiom of this forum.

The premise is that computing and robotics technology leapt forwards dramatically during the 80s and 90s, meaning that the technology deployed in their version of things like the Kosovo, Iraq or Afghanistan conflicts was rather different.
(There is also a second premise, in that magic and monsters are real, although most of the world doesn't know that. Okay, it's perhaps a bit of an odd combination, but you should be under no illusions that my brain works normally).

That's not for here though - if I post anything, I'll put it in the non-spudgun section.

Eh, I'm sorry pigs have to die for ribs and bacon but that doesn't make me enjoy it less.

We've seen cellphones and google maps being used to target mortars in the middle east, eBay drones dropping explosive munitions etc. but I don't think it's radically changed the way such conflicts are fought so far. Even today we're still some distance away from this sort of hunter-killer drone

Well? Inquiring minds want to know...

We may be, but in the setting, they're not.

Developed nations were deploying autonomous drones (drones here covering a range between aerial, humanoid, walking and tracked) by the mid-to-late 90s. Then once international law caught up, it made it all much more complicated regarding how governments and corporations could be held accountable if such a system was to commit a war crime (most likely things such as mistakenly engaging a civilian target or surrendering enemy), so it mostly ended up with operators back in the loop.

Still, it lead to some rather different technology deployed in conflicts like Iraq and Afghanistan - and there is a rather large loop-hole in that emanicipated AIs, albeit very rare, do not count as autonomous systems within the wording of the conventions.

Anyway, something for another thread.

Ah dammit I knew I had seen it before but the Lahti didn't immediately spring to mind...

Sweet! Stumped me... :bom:
