Pneumatic Snowball Cannon

Step 10 Modify the PVC cap

Drill a hole in the cap with the 7/16th drill bit, make sure its in the center, otherwise your snow ball will spin. After that, tap it, and thread your second 1/4 to 1/4 male coupler through it, making sure that you're threading from the side that will end up on the inside. Once all the way through, attach the female to female connector to the male to male one. This will connect the PVC pipe to the air tank. The picture is of the finished connector, I forgot to take pictures of the process.

The part you're showing is a pipe PLUG. If you use a pipe CAP, which is much thicker you will have much more material so it's much stronger. A cap fits on the outside of the pipe.

I figured that out on failure, hah. In version 2, it's a real cap, cemented on.
