i was thinking of changing the back end piece from a reducer to a threaded coupler as show below

That seems a tad tricky, and inaccessible if something were to break
but what direction would it point? im guessin toward the back.

thanks for you thoughts. i'm thinking i should still go through with this. i'm too much of a fan of the game not to :wink:
i'll cope with the lower power. :?
as to the part with the fan, i'm a little skeptical about how effective it'll be. seeing the best spot to but it is right behind the barrel ...

humm ok i'll keep that in mind...
But back to the combustion cannon, with all of your vast knowledge about spuddin, about how less power full would my idea be compared to a regular one. (maybe % wise) just some sort of quick estaminet.

and just another idea, what if i make the barrel in the ...

sorry for being vague.
i meant filling the bottle with propane, then igniting it.
right now i'm thinking that's more complicated than i'm willing to go for.

do you think making the rocket's propellant be combusting propane work like or better than the water/flour?

One other option, is to ditch the whole cannon idea, and turn it into a sort of shoulder mounted water rocket launcher. This gets rid of a bunch of problems in the design, and turns it into a genuine freakin' rocket launcher .

Oh, and if you use flour instead of water, it will look über cool ...

It's really the wrong way round for a full length barrel.

However if you accept that you can't get a long barrel in you can have a reasonable short barrel coaxial launcher and stuff the cannister of gas in the rear section of the launcher.

ya, but it'd be cool to have a gun like the game.
i did ...

So you're going to be setting it up as a coaxial combustion cannon? It looks workable, but not with that barrel placement... There is a severe flow restriction between the walls of the barrel and the narrower part of the chamber.

Is raw power a real goal with this, or is it more for the novelty of ...

here's the gun i hope to make soon. It's supposed to turn out as a replica of the Direct Hit from the game Team Fortress 2
any suggestions or pointers would be helpful 8)
