Depending on the funds you wish to spend there are more then a few options for a vacuum table. One item most folks miss IF not using a vacuum cleaner to generate the vacuum (yes it can be done but requires adapters and still gives a lot of noise) is to not only seal the board if using a wooden structure, but to also put a dust/SWARF trap in between the the vacuum unit and the table. How you place it is up to you. Also IF you set up zones you can decrease the area being used by building a manifold for the table. IF building your own vacuum pump please remember that you REALLY want to have a reserve tank set up and a manifold switch. Otherwise you will burn the motor out way to fast and you will not get a good solid grab as the vacuum is applied via the manifold point.

Those are just points I have learned along the way. Using the design in the video works as long as you SEAL the wood and are able to remove the sacrificial bed once it has been used up (thick means less need to change for loss of depth, thin less loss of depth and more change out). Have fun. -Michael
