i need to know whats the best way to make a piston for a 3/4 inch brass "T" im not getting a good seal with my current one. Also im not sure if its the spring being to strong or if im not testing it at a high enough pressure but i cant get the piston to seal the pilot valve and vent through the barrel. Any help or trouble shooting is greatly appreciated thanks

You can tell how awesome a cannon is by the pressure used.
