I was going to make enough small projects that it would be cost effective to spray the finish. My I was wondering..... If I built a booth about 36"HX36"WX24"D and put the connection to the cyclone in the top of the box, I could stack 3-5 pleated furnace filters on top of each other to capture the over spray. I am pretty sure no material would get into the dust collector. It shouldn't take long to know if the material would penetrate to the top filter and enter the cyclone.

To be clear, the box would have a place to put 3-5 pleated furnace filters between the booth and the blast gate. I could pull the bottom filter and move all those above down, then insert a new one at the top as needed. The power of the dust collector would certainly have enough power to move the air needed to acomplish the task.

I guess my question is "what do you think?" (And we're off!!!)
