It's been a while since I made a combustion cannon, so I decided that I would make a remake of my cean combustion with a couple changes. They both have the same chamber size(3x12), and barrel size(1.5, not the same lenth), but this new one breech loads with a 2in chamber outlet. It also has a change to the handle, which makes it somewhat more difficult to hold, but it's quite sleek.

I took a piece of 3/4 inch, and used screws to mount it to the chamber. It's pretty sturdy.
