I'm currently working on something similar. :D

Sounds cool. Have you made up any plans or done any testing

I still need the parts. I can say that it will be a 3"; that way I can fire my shells (I have two design choices) and maybe those shells from the airsoft mortar. Also It will work like ...

Only problem to me is the tube is so light it shifts, and falls over when you launch so shots aren't that accurate.

Not to hijack or anything but what type of pressure do you think this is running at.
My inspiration and ...

I'm currently working on something similar.

I came up with a very simple way to get real mortar like action that should be legal.

Basically you have your mortar tube with the cap on the end and a glow plug in the center. Then you take your rounds (end cap + pipe section+ coupling) fill with fuel air mixture and cover with saran wrap.

You could almost get away with acetylene!

In my opinion any object that can be thrown up against another person with enough force to harm them can be classified as a weapon. That's why I think firearms bans are so stupid, because even if the people can't figure out that most robberies are done with weapons that aren’t even legal, they ...

All I can say is WOW! Great job!

Well first of all it would be launched from a pneumatic gun.

The whole idea is that instead of wasting a lot of energy moving the rocket from 0-45mph or so, the engine kicks in then and further accelerates the rocket. This could get it going fairly quickly.

I was thinking the same thing for an ...

Is there any difference by using brown sugar instead of white?

I am under the impression that it will have a parachute charge, which is explosive. There is also a limit of 4oz of fuels, etc.

Like I said, it can be inturprited as a legal device, or a DD, it just depends on who you are talking to.
All true. It's just that if you go by the parachute charge ...

You could also try using a two stage setup in which the first stage is the booster. Now what I mean by booster is you have a shell with one end closed off and then when the first rocket motor goes off the pressure will build & eventually break the seal sending the projectile flying. After a bit the ...

Well, when I say faster, I mean I don't want a constantly burning lump of really hot, well, fire. I paintball in some woods and there's a lot of flammable underbrush. I'm trying to get something that will more just poof instead of burn. You get what I'm saying? I don't want burn, I want a big puff ...

This would work good for paintball smoke screens!

Thanks! As you can probably guess I'm thinking of making one myself just for the fun of it.
