I finally figured out why my media blasting was creating so much dust inside the cabinet all of a sudden. Through the repeated clean-outs of the cabinet, I was also recycling all of the dust created from the cleaning process. I decided to filter my blast media to remove the dust. It worked splendidly.
Here is the solution:
I poured the media from a height of about 6 feet into a plastic tote on the floor. As I slowly poured I had an oscillating fan blowing on the stream of media. This caused all of the lighter dusty material to be blown away as the heavier blasting media fell into the box. The trick is to not pour your recycled material too fast. I also ran the media through this process about three times. It came out looking like I had just bought it.
Who Knew?!?!?
I also replaced the window in my cabinet and taped clear plastic onto the inside of the fresh plexiglass. This prevents the media from contacting the surface of the glass itself. When the clear plastic becomes hard to look through, I just replace it. I am using clear 8 X 11 sheet dividers for this instead of purchasing expensive blast cabinet laminate sheets. I made another improvement to the box by sawing a dado into my glass mounts. This allows me to slide in and out replacement glass very quickly.
What's Next: More blasting.
