Another thread discusses using cleats to keep a table top flat. How do you attach cleats while accounting for wood movement? I am thinking you screw one end (or the middle), and then use some slotted holes on the other end? Is there a special slotted washer or other attachment that is used? I am perplexed because I looked at a few commercially made tables and photos of cleats online, and they all seem to be screwed directly into the solid tops all the way across the top.
Thanks.
