compact cannon
you will need
2 feet of 2 inch pvc and 2 feet of 3 inch pvc 2 inch valve and a 3 inch 2 inch coupler 3 inch plug and tire air stem [can be bought at automotive stores and pvc cement and primer.
procedure: [dont forget to glue each peice remember to primer everything or the pressure cannot safely go above 60 psi] together atach 1 foot of 3 inch pvc to the coupler, then atatch 3 inches of 2 inch pvc to the other end atach the 2 inch valve to the length of 2 inch pvc atach coupler to another length of 2 inch
part 2:drill a hole aproxamately 1/2 inch pull the tire air stem through ( this does not need to be glued it is already airtight
part 3 : atatch and glue on plug to back of pvc
ammo can be from model magic and by made by molding it to fit the barrel this is relatively cheap so expiriment a bit i found that cone like shapes with indents in the back fly straight and
i also plan to build one with a 3 foot barrel and a 2 foot air tank made of 6 inch pvc that would have about 4 pumps and atached to it i predict it would shoot about 100 to 200 yards
