Problems with glass bead blasting.
I am taking my first shot at glass bead blasting and running into some issues. Poor visibility inside the cabinet, dust escaping everywhere, and trouble getting a vacuum cleaner to help with the visibility.
My blast cabinet is a small table top model that loads from the top.
The cabinet instructions say it has a dust port. There is a hole in the right side of the cabinet ( no attachment for a vacuum cleaner though) with a cone shaped paper filter on the inside of it. Then there is a foam filter over the paper filter. I am assuming this is the dust port. I rigged a vacuum cleaner connection over the outside of this hole. Maybe that wasn't the right thing to do.
There is also a vent hole on the back of the cabinet with a dense, what appears to be, cloth or cotton filter.
When the lid is closed and I turn the vacuum cleaner on, gloves get sucked in and stand straight out like an inflated balloon. When you put your hands in them, they are too stiff to be useable. If you take the filter out from the vent hole on the back of the cabinet, it lets air in and you can use the gloves but they are still stiffer than if the vacuum wasn't running.
When the vacuum cleaner runs, there is no difference in the visiblity inside the cabinet..... It also seems like when the gun it is working, it is pressurizing the inside of the cabinet and can feel the air blowing through the seals of the door.
There is glass bead dust all around the area of the cabinet. Top, front, sides, and back. Is this normal? I know some gets out. I checked the cabinet to see if all the joints were sealed and they seemed to be. I put masking tape on the outside of all the joints and it actually seemed worse afterwards.
Did I set this up the right and what do I need to change to improve the visibility, keep the dust from escaping, and stop the gloves from blowing up?
