Step 2Barrel
Begin by cutting your barrel and piston pieces. Whatever length you choose, simply cut the barrel and piston pieces exactly the same length.
The 1 1/4-inch end cap needs a hole drilled in the end to become the nozzle. I prefer 1/4" or 3/16". To center the hole, I predrilled a smaller hole from the inside of the cap. (The end of my drill fit nicely into the cap, which centered this little pilot hole almost automatically.)
Use PVC cement to glue the cap onto the end of the barrel piece. I used sandpaper to knock off the sharp edge of the other end of the barrel.
