Re: My Homemade Sandblasting Pressure Pot
This is a detail pic of the top showing the 3/4" loading valve, a shutoff for the air inlet and a third valve to the bottom to control airflow. I will admit that the airflow valve is almost always wide open. Just a warning, some of the valves may seem to be unnecessary, but they are really needed to
prevent backflow of the sand when you depressurize the tank. I put a gauge in the top in an existing fitting, but it's really not necessary, for safety reasons it might be a better idea to replace it with a relief valve.
