Dear Brian,Good question, which I get asked a lot. There is a general misconception that white and yellow glues need air circulation to bond which is not true. They need it to cure but not to bond. Wood glue achieves is intial bond through pressure and capillary action drawing the water in the glue away from the glue line and pulling the glue into the cell structure. This process does not require air to work. This is why you can remove the clamps from glued boards in as little as 5 minutes provided you dont try to work them. This is the bond phase. The cure happens when the water in the wood finally leaves.In a vacuum press the bond phase takes place in the press and the cure phase happens after its removed. Think about a conventional steel platen press. There is no more air circulation in one of these presses, except maybe a 1/4" around the edge, than there is in a vacuum press. A vacuum press also draws the glue into the cell structure where conventional presses rely on pressure only. SincerelyDarryl Keil: I am thinking of purchasing a vacu press,and I would like to know if : standard wood glue(tightbond,tightbond extend) will work in the vacu : press and how it is able to setup.
