I am in the process of building a chest of drawers with two drawers side by side and am using mechanical soft close draw slides. One side of the slides will be screwed to the solid cherry side of the chest. the other side will be screwed to internal dividers. I know that I have to plan for wood movement. For the slide on the solid wood side I was planning on putting a screw in the middle and elongating the screw holes in the metal bracket on each end to allow for movement (why the screw holes aren’t already elongated bothers me somewhat). Assuming that that approach is ok, my problem is figuring out how to connect the other slide bracket to an internal divider. the divider is built on a rail connected to front and back stretchers. the traditional approach when using wood runners is to have the rail free floating via non glued mortise and tennon. If I connect the slide to a divider riding on a free floating rail I am concerned that the drawer will become skewed. If the rail doesn’t float than I am not allowing for movement.
Hopefully the above description explains my concern. Perhaps a simplier way of asking it is : what is the correct way to install metal drawer slides in a solid wood chest? The installation instructions with the slides are solid on this.
I appreciate all thoughts on the subject.
