I have been using a medium size sand in the blasting cabinet but after reading some articles on silicosis I am looking for another media.

Aluminum oxide looks pretty good and should last quite a bit longer. Probably 80 to 120 grit size.

Looking for advice and opinions.

I use #80 aluminum oxide in my cabinet. Tried a few other things, including straight sane and beads, but the AO is the best in my opinion. Lasts a really long time too! I get mine at Harbor Freight, but now TSC carries it here as well.

I have two differnt cabinets, one i built with a completely fold down front door, flood lite on the walls, and is powered by a pressure type blaster using either white or brown sand. It has a 5" exhaust blower hooked up to the back to remove most of the dust and blow it outdoors.

My second one is a factory built unit, that has a rotarty table and vibrator inside. It uses steel shot and is suction feed by stepping on a foot pedal. I like the steel as it isnt as hard on sheet metal as the sand one is. There is very little dust when using the steel shot, but you have to clean it more often as the fine parts clog up the feed tube.
