Since this is largely a woodworking site, I am sure I will be speaking to the choir. If it is an exotic board, be very careful of the dust. Allergic reactions to wood dust is common. It is of no...

I'm speaking from the viewpoint of total ignorance, but: My impression is that a vacuum system pulls vacuum through the entire spoilboard. When the sheet to be cut out covers the spoil board there is...
