Well, I know how but I am open to new ideas. I want to 'UPgrade the bench top on my big bench. I want a flat surface for assembling things. I am very tempted to build another traditional wood top complete with dog holes and vices. But I have a small bench like that the thoughts of building and then spending hours hand planning it flat make me realize that it's just overkill for what I need. I just need a flat surface to work on, not another cabinet makers bench top.
So, tell me how you have built one. I am sort of thinking MDF might make a good flat surface? Maybe a couple layers of MDF? I guess what I am really looking for is ideas on how to build a good frame to support the top and keep it flat.
What ever I build will be covered with tempered hardboard and then waxed so glue doesn't stick to it. When it get damaged it's easy and cheap to replace.
