The tube wich is up is the magazine.There are the balls.In the front handle is the ignition(it gives a continius spark write in the comb. chamber), you can see the battery.The pipe coming out of the combustion chamber is for the air.In the camber there are 20ml of alkohol.Whin I push the triger the fuel (not all ofcourse) burns and a ball is fired.Another ball quikly take it's plase.The air already riched :idea: the mixijure and the alkohol ignite's again.And the proces repeats until it run out of air.With 5L of air it can fire about 20-30 I didn't count them....

simple drop in the chamber design
what kind of pipes are those?

The walls of the pipes are 3mm tick.The gun don't overheat so it's not inportant what is the material.

Oh right I get it now :D , thats a relly good idea. Any chance of a video? I really want to make one, do you think zippo lighter fluid is alright instead of alcohol :?: . Do you have anything blowing in to the pipe to ventilate it or does it do it naturally? Sorry for all the questions but this design is PERFECT for my thompson gun. Thanks a lot and great design :D :D !

Ofcourse it's not naturaly ventilated, why else should I insert comprest air in to that shlank coming out of the combastion chamber?.I think that the alkohol is the best fuel because it can be between 7,5% and 37%(for metanol) to ignite.The nossle for the air shuldn't be very big or it may turn in to a rocket motor :D :D .

Auto-Combustion? If so we need some diagrams, cause I cant see shit in those pics. Rambo I also fixed your posts. You triple posted the gun so I had to delete one and merge the other two, very aggrevating.

The spark is from a "kotlon"(=cooker or hot plate or brazer i don't know just the right word) ignitor.It is very unrelaible.The spark is big as from a piezo kristal.
I just tried it again, you better don't use in non ventilatad room.Yesterday it didn't wan't to egnite with acetone.
the wires should be tick or during the time they'll become a crap.
