I got a really nice light put into my blast cabinet and have used it quite a lot in the last week or so on my wife's Gilson project.
Well today I was going to blast a really rusty rim and even though it was "light" inside the cabinet, I still couldn't see because of all the dust.
I decided to connect the shop vac to the vacuum port to expel the dust. This was a very good idea.
When I assembled the cabinet I used a lot of silicone sealant on all the areas that could possibly leak.
With that being said, I know my cabinet was going to be air tight....In fact, so air tight that the vacuum collapsed the cabinet bending the top piece of metal and busting the glass......Now it is really hard to see into the cabinet.
Note to self.....Remove the vent cap in the back of the cabinet next time I try the vacuum trick!
