Well thats as ghetto as it gets. Quick thinking, i wonder how strong the melted joint is? I also wonder if anyone has made a conbustable out of a coke bottle??

soda bottles have been tested to almost 160 psi before bursting. anso if the class 18 says its rated to 110 psi you can take it higher because ratings have a huge safety margin

The standard pressure for class 18 is 260 psi(kinda lame compared to sch80)so running it 110 is fine.
