projectiles, and you want to fire a whole range of objects from large potatoes, to tiny nails.Maybe you even want a lot more pressure and safety. This instructable will tell you how to do all these stuff and so on and so forth.
And it's mostly recycled, thus keeping the cost down to buying only the plumbers' tape
Oh wait, right, I almost forgot the disclaimer!

P.S. If you want it permanent, use epoxy to seal it up.
and don't forget to rate :)
Step 1: Miniature Barrel Extension
-metal pipe(smaller diameter than the dia. of the PVC)
Just wrap one end of the pipe until it's wide enough to get a snug fit into the PVC pipe.
Step 2: Large Barrel Extension
-Large bottle w/ the bottom cut off
Same thing like before, only you put the tape on the PVC and insert the PVC into the bottle.
Use the picture below.
Step 3: Larger Air Resevoir
-bicycle air valve
same sealing action w/ the large barrel extension.
you must first remove the end w/ the pin. I suggest using the saw because if you just remove the pin you would be left w/ a hole to patch and from my experience its hard to patch up holes when your using pneumatics. Now drill a hole slightly smaller then the valve. If its larger than the valve then use the plumbers' tape to seal it up. It should be really tight when you put it in, that'll mean its airtight, and put plumbers' tape on the spiral groove to make sure its REALLY airtight. Please refer to the picture below.
Step 4: Safety System
-anything that can cut the 'sturdy stuff'
Its simple: the bottle is weaker than the PVC pipe so the bottle would explode, not the PVC.
All you need is something that will protect you from the explosion. I don't have any specific plans so you
can make any sort of protection. Anyways, here's my suggestion: look at the picture below.
Step 5: Operation
You can remove it, you can add it, you can do whatever you want w/ it.

One good reason is because my parents has freedom of information. Thank you for reading this instructable:)
