My largest cannon to date, it's a simple combustion really, nothing too dramatic.

For more detailed information on using epoxy, check out the how-tos here and here.

Nice simple design. Looks very well put together though. Is it painted black in the 2nd pic, or is it just how the picture came out?

Nice, like always FMJ - I mean jackssmirkingrevenge - looking good.

BTW, I see the pack of Marlboro Reds in your avatar's hatband, but what about the ace of spades? :wink: And the bottle of holy water?

I drew that when I was 16, my fascination with the Vietnam war had only just begun so I hadn't had time to collect all the relevant artefacts :p

This is the whole drawing:

I know, I know, the slogan has got more to do with the war in Iraq than Vietnam, but hey, I was young and foolish :roll:

As to the (has to be a Bicycle) ace of spades, well that's a whole new avatar :)

Some more Vietnam related avatars if anyone's interested:
