The combustion provides constant gas pressure to push the bb's, the combustion does not stop,it continues, keeped on with the 1.5 volts bb-sparqer.

The constant combustion you're describing has a technical name I believe...


It's either a blow torch or perhaps a flamethrower.


I'd definitely be looking at metal pellets for that :)

Even with the constant combustion you are talking about, you're not going to get anything close to full auto. Also, you have to be extremely careful when you're dealing with pure oxygen tanks. If it backfires (if that is the term), that gun would blow up with horrendous repercussions. But if you are really want to make it, don't let me stop you. If you can get it working, it would be awesome. Just be careful.

Edit: Plus the flames shooting out of the barrel with the bbs would look awesome, too.

Something tells me the combustion chamber and everything attached to it will become a puddle rather quickly.

Not to mention the intense heat could cause your barrel to lose its shape, which in turn might cause it to jam...then something is going to go boom somewhere.

Sounds cool(hot?) in theory, but somehow I think its more dangerous than it's worth.

Hmm, how about just scewing a blow torch to a iron chamber and having an air flow of soem sort, the air expandes form the heat and propells the bbs, kind of a hybrid BBMG!!! :D

good idea to make a combustion bbmg :D
maybe try to feed a pulse engine with a barrel mounted on (slightly different concept)
where is the topic about that?

Why not just use a pulsejet or a small IC engine, and modify the location of the exhaust ports for more power?

The only problem with that is that you need a considerable amount of pressure to be able to shoot the BBs with any force.

@John: A blowtorch would most likely just melt the iron. They get incredibly hot, and anyway, it would seriously burn your hand if you were to touch it.

This whole topic just seems like a bad idea, and an explosion waiting to happen. Please don't try this, unless you have considerable experience with this kind of thing.

The thing will get hot.
And hotter...
and hotter...
and hotter.
And you know what happens next?
It becomes even hotter!

When it becomes so damn hot, bad things will happen, there are so many danger hazards and probabilities of failing; its not worth it to sum them all up.
You would be better off to use a combustion engine driving a compressor. ;)
