Dear Dean,In general I try to make my table reasonably flat but the flatness of your substrate is the most important part, from my experience. I have observed that veneer is not thick enough to create a laminating effect on the substrate, so if the substrate is flat but the platen you press it up on is not, the substrate will bounce back to being flat after it comes out. Likewise, if the substrate is warped but platen table is flat, when the veneered panel comes out it returns to being warped. Now if the substrate is laminated with something thicker, like 1/8" material, then the flatness that it is when its pressed is the way it will stay.One thing I have noticed, is this, the longer the panel is left in the flatter is seams to stay. Panels I left in overnight always stayed the flattest.SincerelyDarryl Keil: : Darryl,: When veneering a relatively large surface that I want to remain : absolutely flat (dining table top), do I need to be concerned: with the flatness of my work table surface? I understand the: need to not work on sawhorses because of the problems presented : by a sagging vacuum bag, but if I am working on a "flat" table : top which has a slight arch to it, will that arch telegraph into: my platen / caul / veneer / substrate / veneer / caul assembly?: Thanks - love the forum by the way; excellent and fun reading.: Dean
