I like that idea, Hector.
There's a few people on here with machine tools (I'm one), maybe some community machining of specific parts? Maybe a design for a specific high performance hammer valve, something like that?

Re: Is spudding dead?
Quite. And to be honest, the addition of the little "thumbs up" icon at the top of every post does little to help. Gamification of social interaction, it fucking sucks.

I've been through this before, and frankly, it's an awful lot of work and a proper pain in the rear to do correctly.jackssmirkingrevenge wrote: ↑Fri Sep 16, 2022 10:51 amI don't suppose there's a way for PCGUY to automatically update all the broken links?

Re: Hammer & QEV Valve Questions
With a standard hammer valve the hammer has to open *and hold open* the entire valve that's going to be used to flow the air you're using for propulsion. As pressure and bore size go up, you'll need more and more hammer force to open the valve. A QEV + hammer valve reduces the hammer force required ...

Re: Youtube Changes Coming July 23, 2021
That's not entirely true, as I understand it Users with unverified accounts may only post videos less than 15 minutes long. Verified accounts can post videos up to 12 hours long. The cynic in me says it's nothing to do with reducing the amount of time people spend on the site, as that would be utter...

Re: 3D printed internal valve trial
Bearing in mind that I know bugger all about 3d printing apart from what Ive read on line, I think I'd probably be a bit worried about the housing splitting along the lines between layers. Otherwise, it looks proper good and very much the kind of thing I'd machine.

Re: Great video testing spud gun failure/safety (ThebackyardScientist)
Not sure if there was air in the line behind the water, but an interesting result. Definitely, he was pressurising with gas. So there was all the stored pressure of the gas in the line to deal with. Best way to do it is with a grease gun, they go up to stupid pressures (I've done hydroforming with ...

Re: Steel galvanized pipes as pcp rifle air chamber
1500 psi is above the rated pressure for the pipe, which is closer to 750psi. Although it *probably* won't unexpectedly burst at that pressure, but you've blown away any safety margin you have, so any minor damage could be catastrophic. But rather than the pipe itself, I'd be very worried about thre...

Re: I need of dire help (Air Solenoids valves)
Can't help you with solenoids except to say that they're probably orders of magnitude too slow for what you want. I can't even necessarily help with the latter part, but I can give some gut feel. Would like to find out about some new stuff if I can, maybe something along the lines of how much PSI sh...

Re: Convert a Gas refill cylinder to an air cylinder?
What I meant was I'd drill a hole at the end of the gas canister and then epoxy on the Schrader valve in the end for it to accept air instead of gas. But your saying that it's impossible? Nothing's impossible. But at a guess, the walls of that canister are no thicker than 0.5 mm or so. That's super...

Re: Convert a Gas refill cylinder to an air cylinder?
At a guess, that can's gonna be super thin, which would make modding it pretty difficult. I'd be more tempted to look at a discarded 60l oxygen canister or maybe a fire extinguisher CO2 recharge canister. Rather than modifying a canister, try talking to a local machinist, see if they can make up a t...

Re: Thoughts on my piston valve design
> Obviously the downside is the spring isn't variable so a different spring would be needed for a given mix.
A threaded boss at the rear can increase or reduce preload on the spring within a certain range, although this will also reduce spring travel.
