This unit sits inside your blast cabinet, plugs in thru a rubber grommet on the top that goes to an outside receptacle. So you just close the cabinet door and turn it on and walk away.
Allen, the head bolts are large enough to hold in your blast cabinet glove without doing too much damage, so that wouldn't be justification. But don't sandblast your head bolts. They just need a good solvent bath since they are hardened and have no chance of rusting.
No blast cabinet? It WILL change your life. They are amazing and I couldn't do much without it. The Zinc plating process is something I just go to a Plater and have them do. Its about 20 cents a pound.
