This is the Barrel Adapter assembly.
I made my gun with a 2" barrel with the intention of having
the option to add other barrel sizes. I have a 2" coupler on
the end of the barrel with a female adapter that I can attach
other barrels to. The smaller barrel go down inside the 2"
barrel to about 2" for the stopper. I also put a stop in the
smaller barrels by drilling a small hole into the pipe and across
and out the other side. I the treaded it for 1/4-20 all thread.
Then I installed the all thread through and out the other side. i
added glue to the threads and screwed the rod in till the glue
was in the threads on the pipe. I let the glue dry and then cut
the rod off flush with the outside of the pipe on both sides. At
this point I wrapped electrical tape around the pipe covering the
all thread. I kept wrapping the tape till it would just fit
inside the 2" the barrel to help keep the smaller barrel
centered in the larger pipe and to help direct the compressed air
into the smaller barrel insted of some of it going into the space
between the two barrels.
When making a smaller barrel the "downsizing" bushing must have the stop ring removed from the inside of the bushing so the pipe will pass all the way through the bushing.
Larger barrels obviously will not go into the 2" barrel so they just attach with a male adapter and a bell adapter onto the end of the guns 2" barrel.
