Where do you work that you have so much funding and materials on hand?

This will be an awesome gun if it gets built, taking spudding to a whole new level.

Good Luck

In the old thread I said I had the trailer; that there was an old hulk rotting in a field that I was laying claim to.

In this thread I say I have the trailer....


....but it's a different trailer. The trailer I now possess was (a) procured especially for this project and (b) is in magnificent condition.
Hmm thats one step ahead :)
Now do the rest, and realize your dreams.

You should contanct the guiness book of records, maybe theyve got a spot free for you :D

The materials are "free" in that they're stuff left over from past projects. You know, you're building something... You order 1000' of pipe. At the end of the day you have 60' left over. What do you do with it? Well, we hang on to it in case we ever have a need for it and.... Well, that's where all the materials are coming from: the spare parts left over from the past 30 years or so of work around here.

You know, something means I somehow doubt many spudders have ever experienced that...

... but of course, I order hundreds of yards of pipe all the time, and I always wonder what to do with that last few dozen feet because it has me completely stumped every time, but now I have the answer!
:D

Man, I'm in a silly mood.

D_Hall I'm glad to see you still after this cannon! I forgot about it until now.

Ho Lee Crap.

I'm beginning to think that fate is on my side and this thing may happen. In my original post I referenced a requirement for a 100 mm gun that can do 800 m/s. That was based on a conversation with management.

Today, management turned over the actual customer request.

I don't know where he got 800 m/s from. Maybe there's a gun out there that will do 800 m/s and he took that as the requirement? In any event, the actual doctument states a requirement for 333 m/s (1093 fps).

The Pipe Dream can do that!

So now I've got an actual customer requirement and a design already fleshed out. That REALLY greases the wheels for this sort of thing.

Wow 100 lbs at 1k fps?!

Well you don't think a gun that size is designed to launch golf balls, do you?

Well you could fire a grapeshot of ~1000 golfballs. Would be a bit over 100 pounds, but that would be an area roughly 17" long of the 19" barrel full of golfballs.

I'm assuming most ammo will be saboted in a low density material, since a 19" OD x 24" long ice slug would weigh 227 pounds, well over your set projectile mass.

That aside, if you get this built, I REALLY want to see what a 225 pound ice slug at 700 fps with 1 700 000 ft/lbs of muzzle energy will do to, say... a house :twisted:

I have one and only one question- What in the hell would you use this for? And where do you work? :shock:

Thats two questions brogdenlaxmiddie.
And you should make a 1000lb slug aim it at some big tree and see what happens.

Where I work has already been stated in this thread (hint: it's even on this page!).

What I would use it for: Dynamic testing of missile components.

Well, this is the kind of thing that Military PR guys dream of. Something that's big and makes smoke and fire but something that everybody thinks is fun and cool (ie, the anti-military types can't get too up in arms about). So yeah, I see a press release in the future if the gun gets built.

And in that press release? How does, "World's Largest Spudgun" sound?

And if it's gonna be a spud gun it's gotta shoot spuds, right?

I'm thinking that shooting a gunny sack full of potatoes would be appropriate (purely for public relations, of course).
