Re: Sketchup Model Library

Bollocks. Dewey put them out in the hope that, and I quote some of you can make use of these! There's absolutely nothing wrong with using them, especially if you give proper attribution if you eventually publish them. They were made public, with the above commentary. If it's for your own use, and yo...

Re: Sketchup Model Library

Cobblers. And if you don't understand what that means, check it in a cockney rhyming slang dictionary. You don't arf push some pony out yer gary, geezer. If it's for your own use, just take the model and modify it. If you're going to publish it, either post it in this thread with attribution, or pub...

Re: Couple quick Noobie Questions and advice.

As D_Hall says, PVC is a bit sketchy*, and (as with all pipes), pressure rating goes down as diameter goes up. Schedule 80 is better than 40, but it doesn't mean twice the pressure, you get maybe a third as much again. With a longer barrel, you're going to be exposing the pipe to more pressure, and ...

Re: Hybrid velocity

I'm not sure that the speed of sound is an overly useful measure. As I understand it, and I've probably totally misunderstood, even in a "conventional" firearm, the combustion is subsonic even though the actual projectile velocity can be at least supersonic; and that it's pressure and the time the p...

Re: What valve type to use for medium-pressure (12-30 bar) long barrel system?

Yeah, but they are pretty (read "very") expensive, especially in the sizes you're looking at. Expensive enough that it's maybe worth talking to a local machine shop.

Re: What valve type to use for medium-pressure (12-30 bar) long barrel system?

How about piloting a QEV with a smaller solenoid? That should provide a useful boost in performance without having to build your own valve.

nice gun and great work How, in the name of all that's holy, could you possibly know that? The photos are dead, the videos are private, and apart from one post in 2019 the whole thing hasn't been touched since you were literally in diapers. SpudFarm themselves haven't posted since 2017.

Re: P.A.C. 6, Semi-Auto Air Cannon

The website does not work because the entire xinventions site is dead. the page, including photos, is available through the wayback machine, but as they were selling plans, and the people who ran xinventions are not the people you are talking to here , you're unlikely to get the plans by asking here.

Re: pnumatic spud guns

OK, I'm gonna hit you again, perhaps less gently. Quinn. What you are doing is not polite, and at best is creating cleanup work for the moderators. Generally speaking, forums have their own rules, the ones for this one are found here , but there's a more general set of rules that are assumed to be g...
