Wood Movement: box bottom
I'm getting ready to finish making some chests. The original plan was to do mortise and tenon for the box bottom (solid cherry) and glue it in to keep the box from racking. Doug Stowe says use plywood for the bottom and glue it in or leave it free floating if its solid. This makes me thing putting the bottom in might cause the sides to get pushed out and tear the box apart if it swells. If I poly this is it really going to be that big a deal? The sides are held together by dovetails.
I've pretty much ignored wood movement. I know to make sure grain direction lines up, to sticker wood when storing it, plywood doesnt worry about movement and to finish all sides of a project equally. That's it.
