Marble Combustion Gun

[douggie]

Firstly hi everyone this is a great site plenty of info and everyone seems nice enough.
i have made some simply spray and pray pvc tennis ball guns 100mm chamber 65mm barrel (sorry for those using the imperial system).
but i am quite intrested in making a marble gun just wondering what would be they maxium chamber size but dont be riduclus and say 160 mm with a 10meter barel it needs to be resonable sized.

Can be any size you want! Download HGDT (http://thehalls-in-bfe.com/HGDT/) and have a play aout with the settings in that.

I would go for something around 2L, anything more than that won't give you much increase, but you'll need a nice long barrel to accompany it.

Take a look in the combustion showcase and use the advanced search to have a look at guns other people have made for ideas.

Also, do proof-read your posts after you write them, I somewhat doubt a tennis ball gun needs a 100m chamber, and I think a 65ml barrel is a little small.

Nice to see you are using metric though
