Damage pictures woudn't be innapropriate either. For learning German in school, you have pretty sweet English! Either that or our foreign language programs in Chicago just flat out suck...
By the way, welcome to spudfiles!

Wow... That's awesome! I've never seen a trigger like that, but I don't build combustion cannons much. Do you use aerosol cans for propellant? Also, how do you attatch the different parts of the barrel in the second one? And the big question, how's preformance? :P
P.S. Where's the video? I can't see it...

What is with the name 'Kiwi'? Is it named after the fruit, bird or New Zealanders like myself?

In the second, does the barrel just connect like Legos?

BTW: These are nice. Welcome to Spudfiles.

I learnt German in school too, and when I stayed with a French family for two days, earlier this year, they didn't seem to happy :wink:

Oh and for the video, try http://www.youtube.com

Get the URL of the video, e.g and then copy into your post.

Highlight the youtube link, and click the youtube button on the top right of the post window so the link is put into youtube brackets.

Sorry if you don't understand, not sure how else to explain it.

Your gun looks okay to me, I like your igniter alot!
BUT WHOA your C:B ratio is not good.

C:B ratio means the size of the chamber compared to that one of the barrel.
You should shorten your chamber.
Its too big compared to your barrel.
Till the day I'm dieing, I'll keep them spuddies flying, 'cause I can!
