Abstract: A sandblasting apparatus with an abrasive storage tank having a pressure conduit discharging a stream of air proximate to the tank outlet to propel fluidized abrasive particulate toward a Tee whereat the fluidized particles merge with a carrier flow of air for subsequent delivery to a sandblasting gun. The gun is equipped with a nozzle having components joined by silver solder in a manner protecting the components from abrasion.
