Many years ago I was involved in routing about a bazillion shutters for Pizza Hut from 1" MDF. Long story short - this was at a machine tool manufacturer, not a wood shop (we were building their router). The machine was set up with multiple spindles making as many as 4 shutters at once. The volume of dust/chips was absolutely rediculous! I filled a small dumpster with MDF dust every day for about 6 weeks. It was almost fun, actually...I was usually covered with carbide and HSS laden coolant as I was grinding tools at the time.
I guess you guys know the dust MDF can create. It sounded like a good contribution at first. Sorry.......carry on.
