This is a copper piston cannon, made from 22mmm and 15mm pipe. it mainly uses solder joints but there are some compression joints that are used to access the insides of the valve.

The barrel is 1.5 meters of 15mm pipe, it has a "barrel extantsion" "for looks". The chamber is 1.5 meters long and made from 22mm pipe. I pump it up to 120-150 psi, with a potato at 150psi it can split 1/4" pine sheet.

According to GGDT with a:
potato at 120psi, it fires at 630fps
lead slug at 12opsi, it fires at 368fps

lead slug calculated max range:1270feet
potato calculated max range:530feet
