So I want to use butane. I'm using ABS, and I want to fill the chamber with out opening it. If I cut a lighter in half can I use that if I mount it correctly?

so it's abs I went 4" for the chamber 2" for the barrel. I used red hot blue glue for the pipes. I used a weber igniter and Sealall to hold it in.

Use the lighter to fill a syringe so you can put in the right amount of gas precisely.

if you look around there are many hybrid desines that have a valve that is connected to a valve that is conected to a propane tank that you fill the chamber with. but if you are gonna do that you should install a chamber fan(computer fan attatched to a 9v battery) it woll stir up everything and cause a bigger boom. also i think that you may have to open the chamber still so that air get inside. :D

I can't even imagine that even a lighter can be use with this one. Is it not dangerous?

Remember that part of filling the chamber includes both a fresh charge of fuel and the proper amount of fresh air. How do you plan to purge the chamber of burnt fumes if you don't open the chamber? Air compressor?

Why would it be dangerous?
