Welcome sw5amped, I've moved your post to your own topic in the combustion cannon showcase section where people can comment on your cannon.

I've made a topic title for you but feel free to edit it and change it to what you like, just click 'edit' on your post and it should let you change the title.

If you have any other pictures/videos or information about the cannon, you can post it below or edit your first post and put it there.

Welcome to Spudfiles!

Now on to your cannon... Well, it looks like it functions well.

Where's your barrel?
What sorts of things do you shoot out of it?
I'm guessing that unpainted bell reducer contains the chamber fan?
What sorts of challenges did you face along the way?
You see what I'm getting at here?

The more info and effort you provide up front, the more likely you will receive the feedback you're looking for.

By the way, nice camo paint job. How bout some damage videos? Those never get old :D

This is another build of mine......

Has a chamber size of 3400mls and a 46" barrel that's not shown. It runs off of propane and has an on board tank. The ignition is pretty basic but I used a circuit board to createt multiple sparks inside chamber. Also had 40mm internal chamber fan to mix fuel. This gun shoots great every time. I'm going to add a few upgrades such as cosmetic things. Any ideas let me know. Thanks

Hey guys. Sorry took me so long to get back on line to spud files. Thanks for the help with everything. I'm going to post my latest few cannons. This time with all the info and details

This launcher has a 3997ml chamber volume with a 12KV step up transformer ignition. It's fuel is mapp gas with an on board tank. I used a rear clean out threaded cap for a service access opening. The barrel that is not shown is 52" long and 1.5 in diameter. I also used several pvc couplings to double up the chamber wall. The recoil on this cannon is awsome!!!! At 50' I can shoot completely through a concrete block. Ill post some pics.
