Re: Benjamin Model 30/30 CO2 Carbine Repeater "Hot Shot"
I hope it is something simple the problem of your machine. Surely it is so.

Re: A brand-new ignition method
That sounds like it would work, but what sort of mix numbers are you thinking about? I was able to ignite mixes up to 16x using a simple piezo from a cigarette lighter, and about 28x (the highest you can go using just compressed air and not oxygen) with a high voltage stove ingitor . It seems like ...

Re: A brand-new ignition method
Why can't a compressed air-propane mixture burn at more than 28X? I didn't know this, and I don't understand why... It will burn at much higher mixes but if you are fueling with the propane at atmospheric pressure, then 28x is the highest mix you can achieve. If in a closed chamber I manage to intr...

A brand-new ignition method
Hello, everyone, I am from China, and I don't speak English, so the following content comes from Machine Flip: In my country, gun control is very strict, but there seems to be no clear definition of incendiary gun, so I decided to make it. I've been in the forum for a long time, and this is my first...

Re: Can you make a pneumatic cannon shoot snowballs?
Yeah I thought about this too but it would have much more friction and sharp corners would make it unstable in flight. It possibly could even desintegrate in air. Friction for any reasonable projectile is negligible in the "does this thing even work" sense. As for unstable flight, you're going to h...

Is there a more active website than this?
I think I'm late. Most of the posts were made 15 years ago. I missed the most active period of the forum. Is there a more active forum now? Or a telegraph group or something?

Re: A brand-new ignition method
I would like to focus the conversation on the possibility of turning on a high pressure chamber with a lower pressure one, which is the subject of your publication. what you explain about increasing the pressure with two connected chambers, I know well, because I have already talked about it here. ...

Re: A brand-new ignition method
[quote = hect marr post _ id = 390501 time = 1668124175 user _ id = 18293]nI希望将谈话的重点放在用低压腔打开高压腔的可能性上,这也是您出版物的主题。你解释的用两个相连的腔室增加压强,我很清楚,因为我已经在这里讲过了。为了简单起见,我更喜欢使用一个低压点火室,尽可能小,和一个单向阀校准打开需要。我认为它会工作得很好,你必须做一些测试。8-) n[/quote] Well, actually, my secondary ignition device is almost finished.

Re: Is there a more active website than this?
I think the fact that this forum is slightly active at all is because it's more or less the only such forum left, at least in the Anglosphere. There is also the Francophone "Patator" forum that used to be very active but it's even more quiet now, there is a post from more than 5 years ago lamenting...

Re: A brand-new ignition method
You can use my mother-in-law as a target... JOKE! What I'm dying to know is if the whole concept will work well. In my opinion YES! she will do it.

Questions about pressure and flow rate
Assuming that there are two combustion chambers A and B, the volume of A is twice that of B, and the initial pressure of B is twice that of A, then theoretically, A and B should use the same amount of fuel, so their calorific values should be the same. Then the question comes, which one, A and B, ca...

Re: Hpa Dump valve ? Discussion points.
Hi Maybe someone with more experience with the GGDT , Can explain why in the Dump ( 9999+ ms ) of valve . In the results section : the pressure drop is not equal to the pressure in chamber . ( Train of thought if volume of chamber is completely dumped , it would equal the pressure Drop .?) Outside o...
