I am planning to build a bookcase/shelving unit on top of my existing unit, however I'm trying to get my head around how I can best adapt/scribe this to the walls on all 3 sides...
The left wall appears to be plumb, however the right wall has a slight lean to it (represented in the image below). I have not yet checked the back wall for how true that is both vertically and horixontally.
The plan was to not use a backing board as the Mrs has painted the wall behind as to show through and contrast with the wood (emulsion for the wall that "wouldn't" work on a backing board apparently).
I have a few general questions but any other advice is welcomed.
- How much of a gap should there be between the walls and the bookcase for adding a filler piece? If any at all.
- How would I best go about scribing to the back wall if it is off? Each vertical and horizontal would need scribing and that surely would be a lot of work? It's going to be birch ply, so would caulking and painting be out of the question?
