Welcome back to part 2 of my Vacuum Table build.
In this Video I investigate 2 tabletop designs for their holding ability, and talk about the vacuum I purchased for this project and if I get time to clean up my workshop.
I also I have links to the cad files for those who want them.
In the last video I built the table base from a piece on Melamine coated MDF and sealed the edges of it to prevent air leaks. The one thing I learnt for sure was that MDF is a very porous material and when it comes to air you need to seal it. I sealed mine with several coats of acrylic paint though you could also apply edge banding to the MDF as well. In that case you might want to keep the outside shape square for easier banding.
I also made a top that was plain MDF on which I skimmed 1mm of material off the entire back and 1mm off the vacuum area on the front. This is to open up the MDF by removing the compressed surface to get access to the less dense material for greater air flow. I made the tabletop as easy to make as possible as it is the part that will be damaged while in use and a new one can be made quickly once it has no more life left in it.
