I'm finally on the road to building my "final" work bench. I started with a workmate, then went to two sheets of MDF on top of a 2X4 base. My current bench is a frame and panel drawer base made of pine and baltic birch with a laminated SYP top. I've had three different vises in seven different positions and drilled dog holes all over the top and now I think I've finally settled on the final configuration. I'm going to build the base out of cherry and the top out of hard maple. It'll have end caps at both ends and the workbenches I've seen connect the caps to the side skirts with dovetails or box joints. Are these joints glued? It seems odd not to glue them, but if you did, the cross grain orientation of the end caps could pull apart the laminated boards in the top.
