I plan to build a coffee table following plans in Fine Woodworking. In the article, the author uses a plywood top, but I already have solid lumber that I'd like to use.
Source: me, based on plans in Fine Woodworking #242
The author of the article simply screws the cross rails (blue) to the top (yellow), but for a solid top this is not ideal.
How can I attach these rails to the table top in a way that allows the wood to shrink and expand with changes in humidity?
