I posted and asked what was the best method to attach a hardboard top to MDF for my assembly table. Brads was the method I felt best about and used.
The table is 4x8 with laminated plywood legs and rails with 2 3/4" MDF sheets and a hard board top wrapped with red oak.
The top turned out to be 1/8" out of level just on one end with the rest almost dead flat. The end that is a little lower sits across an expansion joint in the concret floor so I'm hoping that maybe thats the reason.
Here are a few pics of how it turned out.
