1. A method comprising:
- attaching an air supply to a longitudinal passage in a manifold assembly, the manifold assembly comprising a plurality of outlet passages and a plurality of material passages, the plurality of outlet passages being serially connected to the longitudinal passage, wherein each of the plurality of outlet passages are oriented in a different direction relative to a remainder of the outlet passages;
providing a supply of abrasive material;
attaching a respective first end of a plurality of material supply hoses to a corresponding plurality of material passages, each material passage of the plurality of material passages being in fluid connection with a corresponding outlet passage of the plurality of outlet passages, wherein each material passage intersects the corresponding outlet passage at an angle to generate a venturi effect;
coupling the material supply hoses to the abrasive material supply at a respective second ends of the material supply hoses;
pressurizing the manifold assembly with the supply of air; and
sandblasting an article by drawing abrasive material through the hoses and out of the plurality of nozzles using the pressurized air.

Abstract
A method and apparatus is provided to simplify sandblasting processes while increasing applied coverage areas in sandblasting operations. The method and apparatus provide a manifold assembly having a plurality of nozzles and that is rigidly attached to an air supply. The manifold is supplied with abrasive material via a plurality of angularly attached sand supply hoses which are coupled to an abrasive material supply. The manifold assembly is pressurized with the supply of air. An article is sandblasted by drawing sand through the hoses and out of the plurality of nozzles using the pressurized air through the manifold assembly.
