I figured that out already. I got everything now except for the 6" pipe for the chamber.

the 4"sch-80 fittings I got were expenmsive, I can only imagine for the 6"
Only reason he wrote STR is because we've been discussing this cannon through speech, not over the internet where you can see spelling.

Yes, it will be pretty expensive. Only reason it won't break 200 is because I gave him the pneumatics as a Christmas gift.

Also, why'd you get SCH-80 fittings? Just normal SCH-40 will do for a combustion. Even the 6" we got was SCH-40. Rated to over 100 PSI.
My gun will have hybrid capabilities.
