im new to making combustion guns. i have make a big pneumatic, mini pneumatic, and a mini combustion. i was wondering if the combustion chamber has to be pressure rated as it isnt holding pressure, just directing it. i was also wondering whats the point of removing the sparker from the bbq ligter ...
