Hi all..

A few years ago, I went to the NEC to drool over some ready made CNC machines.. On one of them a vacuum bed was being shown with a MDF waste board mounted on the bed.. When I asked, I was told that the MDF was a 'special' type that was porous and allowed the vacuum to grip boards through it..

My local supplier thinks I had a too many sherbets that day and that such a thing does not exist.. Anyone out there share my hallucination and know what this MDF is called?

Thanks..
Steve..
