True, if something has the right properties, SHOOT IT AWAY

That will decrese performance ALOT
And sometimes it may be so much the projectile will be stopped in the barrel or even sucked back in the chamber then.

It looks awesome!
Build a gun around it as fast as you can!
And then build a BIG gun eh

I bet it will be one hell of a monstergun.

that looks really nice

What kind of projectiles you shoot?

I recommend a ratio of .6 to .8 for a quiet gun, the lower the ratio, the more quiet the gun. Though dont drop it too much or you will lose performance really quick. Take a look at this test result: http://www.burntlatke.com/jpg600/15cb-graph.gif a .5 ratio could also be done for a quiet gun but don...

Use acetelene!
Not everyone knows that thats an "explosive" gas.

Do take PVC pipe, not ABS coz of the cool schrapnels.

Ah so you will be going to create an uber design in the next few years and then come out with some sort of nuclear powered particle accalerator?

k... cool

I like... -Things that can cause alot of destruction in a very short time or launch things with insane speeds. -Doing stuff with friends -Being in a insane hurry -Annoying people (sorry, its just so funny) -Everything that belongs to my style of music (180 BPM gabberhouse and stuff) -Constructing th...

That vid is very very nice! My idea: Havent tried yet but I was thinking of a foam sabot with a small but long steel pointed and sharp pin in front of it. The idea is that the sabot gets pushed VERY hard by the pressure on the whole back surface and the pin gets almost all the kinetic energy since a...

It looks nice and harmless
Wire a small piezo through the hole and put duct tape over it.
Then it will perform better i think

Getting the parts is easier than assembling them.....
Look around, go to every store you think they might have it.
That includes all home improvement/DIY-stores or however you call that.

It is a bomb, but you need to make your parents believe its all not very dangerous. I suggest you building a pneumatic. And then i mean: a POWERFUL pneumatic thats WAY WAY WAY more powerful then any of your combustions. Show em that and let them choose: -Burning Propane, launching a spud fast -Relea...

man arent you angry now? i mean, just having to stop spudding is a HUGE restriction.... and unfair and the penalty from your school is the same unfairness Go on a rampage! Rain chaos and destruction!Show them the power of potatos! :twisted: no, but cant you just hide the hobby from your parents and ...

Try venting it for an hour, and then put VERY LITTLE fuel in. I think you got too much fuel. A rule of thumb is that when a combustion doesnt fire coz of fuel problems, you got too much fuel, never too less. I dont know how small your chamber is but on mini guns it can also be useful to spray little...
