I'm planning my bench as I've said. The top will be flat sawn boards standing on edge and face glued together, butcher block style. My question is about the aprons. I see these pictures of these nice dovetailed or finger jointed corners, but what about the movement of the wood? If I dovetail the front corners and glue them, then on the ends use a long M/T joint kind of tongue and groove style (not sure what that's called really) and pin it similar to bread board ends I think I'll be ok... but what about the back corners? If I dovetail them too then the top won't have anywhere to move. I could finger joint them and leave them unglued. Anyway what have you seen or what would you do?
Most of the pictures I've seen are amazingly unclear on this point.
