The Pipe Dream: I think it's going to happen

[D_Hall]

Man, you've been looking forward to this a long time D_Halls, I can tell. Is this what got you interested in combustion guns?

Yes, the Pipe Dream is why I'm working in the combustion world these days. I need the hot gases to break Mach. Were it not for that requirement, I'd just make it a Very Large Air Gun.

[D_Hall]

And pipes. We have pipes!

[SpudFarm]

those pipes does not look suitable for a hybrid.. what is the wall thickness?

[D_Hall]

IIRC, it's 1/2" wall. Correct in that it's not much, but then, I'm not planning on putting much through it. It's good to 200 psi with a 5:1 margin. Totally adequate for a 2X gun.

just don't "ride" it as Adam did with the chicken gun

Are you finding combustions interesting enough to become a permanent convert? I know (or think anyway) your first love is with pneumatics.

@D_Hall

By the looks you have a vast open space to shoot this thing, that means you have a vast open space between you and the cannon...I think you can go more then a 2x

[SpudFarm]

mrcrowely: mabe it can get DDT

[MrCrowley]

You'd probably need 100' of chamber that size to get DDT

[SpudFarm]

BTW how long is the chambers?

[D_Hall]

By the looks you have a vast open space to shoot this thing,

I have access to a military gun gun range (and I'm not talking about small arms). Ironically, said range is about 1/2 mile beyond the horizon in the "pipes" picture. So yeah, I have vast open spaces available to me.

I think you can go more then a 2x

LOL. Yeah, but if the gun WORKS, then I'm a dead man if I push it too far. Too, IF the gun works, it may be a lot easier to get funding for something "nicer" if a need is identified.

[D_Hall]

BTW how long is the chambers?

10' long. Total volume is on the order of 170 ft^3.

[OuchProgramme]

I think you should build a house, and then shoot the 250 pound projectile at it .


Ultimate damage pic.
I'd pay big money to see it

[bigbob12345]

Mind if you take a pic of the pipe with some other thing for a comparison of size.

@D_Hall just wondered what type of place you work for? If that's too much information, just don't answer. I am expecting a little $$$$ soon myself and would like to maybe start a company(in the air rifle/ spud cannon business).
