That is a nice looking job.
To get the initial grab for a large piece of material you could try installing a vacuum reservoir and a ball valve between the reservoir and the table. This way you can pump the reservoir down and when you turn on the vaccuum to the table you get a large suck that helps snap the material down against the O-rings and give the final tight seal.
