well this is my big advanced combustion. it has a 4' by 3" barrel and a 2' by 4" chamber. I painted the whole gun black and painted the handle and propane bottle holder red. I have not had a chance to shoot it because i finished putting it together at 9pm. hopefully you like it :)

Looks pretty good, you don't see very many large bore combustions much it seems so its nice seeing one.
Any ideas as to what your primary ammo will be?

Powerful :)

I just have a question. What did you use to connect the meter to the chamber and what did u use to tighten that piece.

Also can you take a look at my cannon and see if you have any reccomendations.

You mean the street elbow?

Well you just attach your meter pipe to it, and start spinning it round to thread it in the chamber. Though you may have to take everything off if you want it to get it off again.

Nice cannon BTW.

Yea i see that now (Thx) but i was just wondering cause my meter leaked a little by the threaded are and my street elbow is 1/2 and i dont have a 1/2 inch drill bit (or whatever you use) So i had to go with using a pipe nipple. I just wanted to know if his leaks by that area at all.
