OK, here's my thought ... my worktable is frequently scarred by working blades across its surface. So why not a dual layer worktable? The expensive piece would be the bottom layer due to the necessary machining required, but couldn't the top layer be a thin (say 1/4 inch) layer that gets replaced when all marked up? It should be far less expensive to make and could sell at a much lower cost as it would simply be a rectangular piece with four countersunk holes. For now, I periodically run my circular sander w/ 120 grit discs across the worktable to keep it smooth. Hmmm, maybe I can make this modification to my existing table??
