cutter.

chamber pipe (Fatter, sorter one) Make sure you don't get glue into the threads.
-
Take the 3" to 1.5" reducer and glue the 3" end
to the other side of the combustion chamber.

Next glue the female treaded coupler on to the barrel, and the
male onto the reducer (you may need to use a small piece of pipe going from the reducer to
the coupler.)
