THE BEST AMMO FOR THIS CANNON IS PAPER DARTS. they are even simpler and cheaper to make than the cannon. I cannot take credit for this because i found this from someone else but i will put a link for it.Paper Darts
P.S. yes, i did use a few images a couple times.
Step 1: Materials
1- long piece of 2/4 inch PVC piping, buy enough for your standards; longer or less depends on you
1- ball and socket valve 3/4 inch
1- 3/4 inch end cap
1- tire valve replacement from autozone or pepboys etc.
1- can of PVC cement
hacksaw or radial arm saw
bike pump WITH PRESSURE GAUGE
DISREGARD THE PIECE THAT IS CONNECTED, THE TWO ELBOWS AND SPLIT PORT, it was for an add on but i messed it up =/
Step 2: Measure and cut the pieces
measure the height from where it is comfortable to hold the barrel at to fire to the top of your shoulder so you can shoulder mount this.
cut the barrel long enough but don't overkill this.
leave the rest for the compression chamber.
Step 3: Cement!
glue all the pieces together and push together with a lot of force for about 2 or 3 seconds to get a good hold.
DO NOT CEMENT THE END CAP YET! IT STILL NEEDS THE TIRE VALVE!
Step 4: Drill!
you will need a bit that is slightly bigger than the bore of most of the tire valve so it sticks out but gets the other end caught.
drill the hole and make sure the tire valve is facing out the exit side of the end cap and clears it.
super glue the valve into place. (I've tried to glue it on the inside but it's very difficult and glueing just the outside works just the same.)
