Hey folks. Happy holidays and thanks for reading.
I’ve been pondering a couple of problems related to wood movement in regard to a prototype bookcase I recently completed. For reference, here are some pics (More can be viewed in my “projects” page as well as my website blog).
So, one regret I have with this piece is that the top molding is not keyed into the case in any way to allow for wood movement. I’m familiar with a sliding dovetail when attaching side molding to a lid, say, in the case of a large chest – where the tail would be routed into the edge of the lid and the socket routed into the back of the molding, then attached – simple enough.
But here, we have a dovetailed top. My first thought is to use a spline joint, glued into the molding, glued to the case at only the first few inches of the front, then shot with an inconspicuous nail or two at the back to hold tight.
What troubles me though, is the idea of a groove for the spline joint (I’m thinking 1/4”w X 3/8”d) cut right through the sides of the dovetails – It seems to me, the spline should be fairly close to the top surface of the case (hence, through the tails) to better insure a tight seem between it and the molding. Nothing would be visible of course, but structurally, it just seems weird.
Has anybody else dealt with this particular situation? Seen a good example of how others deal with it? I see pictures all over, of a dovetailed case wrapped in molding like mine but nothing where I can get a good look at the back to see how the molding it was attached.
Thank for any advice.
