I want to make a router table top. Most plans for router tables show the tops as one or two layers of MDF. A few show plywood. Plywood is not usually dead flat like MDF. MDF is flat, but doesn't hold screws well. I was wondering if a combination of the two would be good. I am thinking of using plywood for the bottom and MDF for the top. The bottom plywood would hold screws well and the top would be dead flat. What do you guys think? If the top is covered with plastic laminate, should the bottom also? What kind of glue would you use, yellow or contact cement? Thanks for your help.
