Glue for dados and sliding dovetails

[Todd Zucker]

I am getting ready to glue up a solid wood credenza and angsting about it.

The middle shelf is attached to the case sides with sliding dovetails (about 17"), and the vertical dividers are in dados (about 14").

Is it a bad idea, from a wood movement standpoint, to glue the entire length of the sliding dovetails and dados, versus just the front few inches? The grain all runs in the same direction, and it's all the same species, but the components are all different thicknesses (top and bottom are a little less than 1", shelf is about 5/8", and the dividers are anywhere from 1/2" for the curved ones to a little less than 3/4" for the others).

For racking strength, I am intending to glue in the back, which will be 1/4" ply.

Since the grain is going in the same direction and is the same species gluing it would be fine, however it only needs glue at the front.....Rod

+1, I glue the front only.
