If you find yourself in need of a blasting cabinet, it is not a difficult venture to build your own to suit your personal needs. The cost is nominal and the benefits are great. Follow these instructions and you will find that in no time you have your very own custom-made blasting cabinet.

Step 1 - Prepare Assembly Parts

After determining the size of the blasting cabinet you want to build, measure and cut all the pieces of wood. You will need six total—four for the sides, one for the top, and one for the base. Drill pilot holes in each of the edges to attach and assemble the box. Cut a rectangular hole in the piece of plywood that will be the lid of the cabinet and attach weather stripping around the edges of the hole. Place the plexiglass on the weather stripping and attach to the lid using bolts and washers to hold the plexiglass tight against the weather stripping in order to keep the blasting material from coming through. You can cover the plexiglass' internal surface with an acetate film that can be replaced when it gets pitted from blasting. This can be easily found at most art stores. Screw hinges onto the edge of the lid. Cut two holes to accommodate your forearms into one of the sides of the box and one smaller to accommodate an air compressor hole; take note whether you are left or right handed for the hose hole. Attach grommets to each hole to help reduce sand leakage during blasting. These will be armholes, which will facilitate blasting.

Step 2- Assembly

Run a bead of wood glue along the entire edge of the plywood, put the pieces together and screw in place. The glue will keep the blasting material inside the box. Attach all the side pieces together first with glue and screws. Attach the bottom of the box in the same way, using glue and screws. Glue weather stripping around the top edge of the box. Attach the top of the box by the hinges. Connect the hook and eye hasp to the lid and the box to keep the lid tightly down on the weather stripping for a good seal.

Step 3 - Finishing

Use the sand paper to smooth any rough edges around the blasting cabinet. When you are blasting, you will be in close proximity to the box, so in order to avoid unnecessary injuries, sand the arm entry holes smooth. Put the sanding gun into the box and run the compressor hose through the small hole and then to the blasting gun. Be sure to wear safety goggles and gloves when using the sand blaster to keep yourself safe from harm.
