re: Bench design

Edges are chamfered and more sanding done. I think I have the needed pieces cut to fill the gap under the top. Tired so will attempt the glueup tomorrow so I don't stumble here with the finish in sight. Sat on it and it feels very solid, even with no glue yet. I think glue in the dadoes should be all that's needed? Not sure what other fastener to add anyway.
