Shop Vac Sucks Dust Out Of “Glass Blaster”
![]() |
![]() |
“The beads shatter and make a lot of dust, which ends up airborne and goes everywhere. When the cabinet is pressurized, they blow out from every possible hole and you end up working in a cloud.
“So I hooked up a shop vac to the side of the cabinet to turn it from positive to negative pressure and stop the leaks. I made a bleed valve so I can easily regulate the amount of vacuum in the chamber. If there’s too much, I can’t open the lid and it will pull the gloves off their mountings. I adjust the valve as I work because the filter in the vac gradually clogs up.
“I made the valve from pieces of tubing with large holes cut in them. By turning the outer pipe I can open or close the holes to control the amount of vacuum.
“This setup works well in my shop – but you do want to have the most quiet shop vac possible because you’re standing right next to it.”
