I have basically roughed out and completed one wall of a library system. I was at odds on how to get the crown to come together on each module. While talking about this with a friend, he gave me the idea of setting the crown out about .25″ on each end. It was a great idea and also simple. I had imagined a corbel or something in between each section. This works out much nicer. Thanks for your input Doc!!. Now to finish sand, stain and clear coat . After that I will attach the rails for a ladder system then put them in storage so I can make room in the shop for the second wall. Oh,I have to make a ladder and put ambient lighting inside the top also.
