Attaching Crown to Built-In
Building a full-wall frame frame style bookcase that spans inside corner to inside corner. Was thinking about going with crown at the top, coling it to meet the other two walls.
Having trouble deciding height. Was thinking I'd place the top carcass piece so that its at the right height to nail the crown to the edge. But that's an awfully exacting height on wavy floors, walls and ceiling.
How can I cheat that? Lay a scrap piece or two of ply on top to act as a nailing strip?
