I have never seen 6" pipe at any hardware store so thats why i couldn't wait to ...

i made the chamber by cutting a piece of pipe and glueing the couplings and reducers on the ends. the only piece that i cut down length wise was an extra piece of 6" pipe i had then i sliped it over the chamber for some added strength

I found some 6 inch abs sch40 cellular core pipe at work the other day and decided to use it to make a huge potato gun. the chamber i built with it is propane injected and is 32 inches long. I double layered it buy cutting a seam down the side of another pice of the 6 inch pipe and glued it over the ...
