Hello,
I'm about to start making a free-standing bookcase. When finished, it will be 20cm deep, in four separate sections, each about 70cm wide, and separated by vertical supports 250cm high. I was planning to cut slots in the five supports with the router to take the ends of the shelves. When finished, the bookcase will be screwed against a wall.
My question: is it a good idea to glue the shelves into the support slots? I was thinking from the point of view of the expansion/contraction of the wood during the year due to moisture changes. The room is centrally heated.
Many thanks, Paul
