im trying to make a micro launcher out of about 4" of copper pipe my previous attempt was that i put a plastic barrel on it and a silicon end plug but i had to place a bbq sparker wire in the middle of the copper pipe with the other wire rapped around the pipe and loading it with hair spray was hopless.
any advise or criticism would be helpful

I am also working on a marble launcher with a meter of 15mm electrical pipe as the barrel and i was thinking of a combustion chamber around 40mm wide and about 6" long with a bbq sparker as the igniter my largest problem is finding reducers.
and advice or criticism would be apprieciated.

Advice: Don't use the hairspray... find a cheaper fuel source that wont gum everything up. Trust me in the long run it'll work out better.

i have always used antistatic spray. its pretty clean too. and the only thing cheaper is propane. hairspray is like a dollar a bottle.

oh ok i will give it a go im workin on a whole new design for my micro launcher at the moment so wen i perfect it enough i will give it a go thx

make a pneumatic damb you!

i like combustion better

Pneumatics rule this planet!

combustion all the way

Combustions are old news go with something pneu and powerful... haha

good one lol.combustion has a few advantages.....fire....muzzle flash....flames.......combusting

Both hve there own advantages and its all wat u r into i spose but i like flames and combustion myself and if u like pneumatic good for you

use a pneumatic please. much more power. plus u get smoke that comes out the barrel and makes it look like a real gun yea

im making my marble launcher combustion but im thinkin of my micro as pneumatic gun so ill see
