I am building a large, expandable dining table using solid quatersawn white oak. 80"L x 46"W when closed without leaves. The grain in the top will run width wise so I have wood movement to consider when installing the slides to the bottom of the table. I am concerned that if the slides are attached solidly with tight screws that there will be issues with the wood movement. If they are mounted "snug" with oversized holes to allow movement, the slides will not be rigid when the table is opened. The slides will attach to 34" of the top on each side, which I figure is a 1/4" of movement I have to allow for.
What is the best way to attatch the slides securely?
You're right to worry about screws and wood movement, but this is a fairly easy problem to solve. Leave the screw hole nearest the center of the table at its normal size, and enlarge the remaining screw holes.The smaller screw hole prevents the slide from moving, while the enlarged holes allow the top to move.
When you install the slide, rub two 2" long triangular-shaped glue blocks onto the slide and table top, near the center of the table. This further prevents the slide from shifting.
