Blast Cabinet Visibility

I built this one. obviously some idiot did. the windows went where the raw wood is. It had a two stage sloped wood cavity in the back that lead to where I hooked a shop vac to at the bottom. It had rabbit wire as a floor above the slope to lay my parts while I blasted. I ran my pressure blaster into it. But it pissed me off because the slope was not steep enough and like 50 pounds of sand filled up in the rear chamber and it was too cumbersome to use. So I burned it to the ground.
