Thats a hell of a cannon you got there. Muzzle break looks awesome too. Some pics would be cool though. 8)

That looks like something out of starwars. That is a pretty neat gun!

Impressive, good job! Is it accurate and consistent enough for the scope to be useful?

@marcin: I merged your picture topic with this one, minus the pictures. Please repost the pictures either in your original post here with the edit button or as a new post below. If you edit your original, your pictures will show up top with your YouTube video.

Awesome combustion project! Great paint job and general layout and construction. It would be nice if you could write up a basic description talking about cannon specifics, spark source, c:b ratios, ammo, fuel system, etc. Also a few more detailed, close up pictures would helpful. Some of your others were somewhat redundant.

Starman - pardon my poor forum etiquette I will repost some pics to this thread soon.

Thanks for the compliments guys!

The scope is real but the accuracy just doesn't hold up with a spud and a rifled barrel. Better ammo might be prove otherwise.

Potatoes are just about the worst projectiles imaginable for both accuracy and destructive potential.

Our benevolent sponsors have shown that with properly engineered projectiles, rifled barrels are not needed for scope-worthy accuracy.
