It's been better. . .But I was force fed water before I slept(passed out)so that helped a bit.Cheap Australian made vodka :roll: . . . .Nuff Said. . . .

Got a rough Idea on how long until you start this project?and cold castable?I don't no to much about polymers,so I'll just agree :)

I am not quite getting just how you make your porridge Pizlo..
RNA, the poly is simply a two part mix- Part a is like a clear syrup whilst part b is more like thin honey (and the same colour). You mix the two in varying ratios (90a duro is a 50/50 mix whilst 95a is a 100/15 mix, the composition of the part b is the only real change). It sets hard in about 2 hours and full cure (90 percent cure) takes around 7 days. It continues to further toughen with time, however it does get cloudy also..

95a is a 100/15 mix


Interesting how you've got 115% percent there, isn't it? :lol:

A spherical tank would yield optimal combustion speed once detonated in the center.....
There is no reason for pneumatic.
Combustion or hybrid, or maybe bbmg cloud as some1 alsready suggested.

JSR can you make a prototype for a gun that shoots its chamber off the gun at something,instead the projectile in it?

That would make it a rocket if I am not mistaken.

You mean the spudgun equivalent of the Gyrojet?

While this is practical for solid propellants - that store a lot of energy in a small volume - it's less practical for pneumatic or combustion spudguns, where in order to get enough practical energy you need either a large volume (and correspondingly massive projectile) of compressed air or fuel-air mix, either that or high pressure that needs a very strong container and would therefore be heavy and impractical.

The closest practical thing I can think of is using a CO2 capsule as a self-propelled projectile, that or a water rocket ;)

Hmm, what about some sort of 10x mix high pressure water rocket...

The Gyrojet hey, is there any other information available?
J. Edgar sucked ass- literally. Why would the FBI have a chief of staff equivalent to Mr Mackey is beyond me (not really, bloody lacky), he even said that the mafia didn't exist. :lol:

You can have a look at the wiki entry. As it fires a rocket, it's useless at short range because it doesn't have time to accelerate, but this seems to have been the only disadvantage - but this same property would make it a killer long range anti-material round. Since it's accelerating, not slowing down, as it travels further from the shooter, meaning the trajectory would be exceptionally flat and make aiming easier.

Kinetic energy rockets are nothing new, the Line Of Sight Anti Tank weapon has no warhead but can kill any modern Battle Tank by sheer impact (the whole missile weighs 80kg and screams along at mach 5):

Also, in WW2 the British 3" rocket was sometimes fitted with a steel head and used to good effect against both tank armour and U-boat pressure hulls.
